- 00:00(ambient chatter)
- 00:08- [Sten] Good evening.
- 00:09My name is Sten Vermund.
- 00:10I'm the dean of the School of Public Health
- 00:12here at Yale university.
- 00:13I wanna welcome all of you
- 00:15in the Winslow Auditorium this evening,
- 00:17as well as those of you joining via live streaming.
- 00:21Thanking in advance our speakers who
- 00:24have joined us this evening on short notice.
- 00:27My only duty this evening other than
- 00:29to quiet the crowd is to welcome
- 00:33this evening's moderator and introduce him.
- 00:36Dr. Saad Omer is director of
- 00:37the Yale Institute for Global Health.
- 00:40He is an infectious disease epidemiologist,
- 00:44a vaccinologist, and a physician.
- 00:47He's also a professor of medicine
- 00:50in infectious diseases at the Yale School of Medicine.
- 00:53He holds a Susan Dwight Bliss
- 00:54Professor of Epidemiology of Microbial Diseases
- 00:57at the Yale School of Public Health
- 00:58and also has a secondary appointment
- 01:01in the Yale School of Nursing.
- 01:03We are lucky to have Dr. Omer here.
- 01:06He is the inaugural director of our
- 01:07Yale Institute for Global Health.
- 01:09And without further ado...
- 01:11(audience applauding)
- 01:19- [Saad] Thanks Sten, and besides being
- 01:23the dean of the School of Public Health,
- 01:25we at the Institute for Global Health
- 01:28are privileged to have a true pioneer
- 01:30in global health, Sten, as one of the deans here
- 01:35as the dean of the School of Public Health.
- 01:39And he's one of the founding fathers
- 01:40of the Institute for Global Health.
- 01:41So it's a privilege to be here
- 01:44and talk about this important emerging public health issue.
- 01:49And, just to outline what we'll be discussing,
- 01:52we'll be discussing the academic response
- 01:56of the various parts of the university, not university,
- 01:59the University and the hospital as an institution
- 02:02which is located in New Haven, et cetera,
- 02:06and interacts with its communities.
- 02:08It is a part of it, but our focus here is
- 02:10as an expert panel covering various issues
- 02:14from an academic and research perspective.
- 02:17And there have been other panels in the past few days
- 02:23and in the last week or so in the university,
- 02:26but this one has a focus.
- 02:28We want to do a comprehensive focus
- 02:29on a few issues ranging from epidemiology,
- 02:32to communications, to virology, to some aspects
- 02:35of preventive measures
- 02:38and the public health response, et cetera.
- 02:41I wanna, before I start, I will start with
- 02:45a few overview slides.
- 02:48And then, I'll welcome our distinguished panelists.
- 02:52And most of the session will be based
- 02:55on questions and answers.
- 02:57I'll go through a couple of rounds of questions
- 02:59from the panelists then we'll open
- 03:01this forum for discussion.
- 03:04We have a really good and solid, rich base of faculty
- 03:08and students who have a lot to contribute.
- 03:12So please, feel free to contribute.
- 03:14I wanna thank, in terms of organizing this, specifically,
- 03:19YSPH's Department of Epidemiology of Microbial Diseases,
- 03:22especially, Albert Ko, who was very instrumental,
- 03:25I don't know where he is, I don't see him right now,
- 03:27but I'm sure he'll come.
- 03:29And he was instrumental in choosing the panelists,
- 03:33et cetera, and was very helpful in organizing this.
- 03:37I also want to thank Global Health Justice Partnership.
- 03:41Gregg Gonsalves, who's one of the panelists,
- 03:43and Amy Kapczynski, and a few others
- 03:51who have been really helpful.
- 03:53Yale is very privileged to have long-standing collaborations
- 03:57with our colleagues in China.
- 03:59And there are a lot of efforts going on,
- 04:02especially, for example, there's a coronavirus
- 04:06working group focusing on a few research questions,
- 04:09which is very driven by our Starlight Fellows.
- 04:13And I would encourage colleagues with connections to China
- 04:18and of Chinese heritage,
- 04:19to contribute in today's discussion.
- 04:23So without further ado,
- 04:24I will start with my introductory slides.
- 04:33So we know that the initial cases were identified
- 04:38and reported from Wuhan City in China.
- 04:43And it is an unfortunate aspect
- 04:44that some people call it a Wuhan coronavirus.
- 04:47I'm very uncomfortable,
- 04:49and a lot of us are very uncomfortable,
- 04:50labeling this virus with a place
- 04:54and adding to a little bit of culture of stigma
- 04:58that sometimes evolves.
- 04:59But it was identified, it's appropriate to say,
- 05:01it was identified, initially, in that place.
- 05:04It has now, as of this morning, it's spread to 28 countries.
- 05:13And this is a map, but there's also,
- 05:16there's some sobering reflection
- 05:17on the status of the outbreak in the sense
- 05:19that the major chunk remains in China,
- 05:23and the major chunk remains in mainland China.
- 05:27There have been over 28,000 cases reported.
- 05:33There are model-based estimates that go
- 05:36much higher than that.
- 05:37But, in terms of reported cases are 28,353,
- 05:43including, unfortunately, 565 deaths.
- 05:47And that's a very sobering reflection
- 05:52on the status of the outbreak.
- 05:54But when it comes to emerging diseases,
- 05:56it's not just that we are concerned
- 05:58about what has happened so far.
- 06:00And can you imagine that, during the holidays,
- 06:03most of us had, in fact, yes, I was looking
- 06:06at the reports,
- 06:07there were emails circulating in early January,
- 06:11starting in late December there was something percolating.
- 06:13But we didn't know about this major outbreak.
- 06:16Certainly, it wasn't common knowledge.
- 06:19It wasn't a major concern and how quickly this disease
- 06:23has become a major concern.
- 06:26We think the family of viruses it comes from,
- 06:31it sort of tells us that it is likely
- 06:33to have the more prominent host as a bat virus.
- 06:38You know, when you use icons sometimes,
- 06:41they look closer to Batman symbol.
- 06:44(audience laughing)
- 06:44But, you know, take my word, it's a bat.
- 06:46But there is a possibility of an intermediate host.
- 06:52Having said that, there was a lot of rumors~
- 06:54and sort of preprints that were shared.
- 06:57Someone looked at the receptors and had some speculation
- 07:03that we have a snake intermediate host.
- 07:06And, no matter what you guys do,
- 07:08don't call it a snake virus.
- 07:10There was a headline, not in the Baltimore Sun,
- 07:15in the Scottish Sun-- Baltimore Sun is a much better paper
- 07:18that the Scottish Sun --that had this snake flu headline.
- 07:24But, obviously, it got transmitted to humans.
- 07:26And what really concerned us,
- 07:28was the well-established human to human transmission.
- 07:32Because when things come from zoonosis,
- 07:36when there's a jumping of a virus or a pathogen
- 07:39from an animal host to a human,
- 07:43that happens with some frequency.
- 07:45But what really concerns us is when
- 07:47there's human to human transmission established.
- 07:51Just to give you a little bit of a big picture estimate,
- 07:54so one measure of transmit-ability
- 07:57is the so-called basic reproduction number.
- 08:00Some people call it basic reproductive number.
- 08:02That's not a preferable term.
- 08:03Basic reproduction number, meaning,
- 08:07one way of conceptualizing it is that in a naive population,
- 08:12where everyone is susceptible to this infection,
- 08:17if there is one case introduced of this disease,
- 08:21on average, how many cases they would infect?
- 08:25So that's one simple way of understanding this.
- 08:27And this is a measure of transmit-ability.
- 08:29This is not the sole predictor of how big,
- 08:32how dangerous the outbreak will be.
- 08:34But it is an important measure.
- 08:36There's some uncertainty about the magnitude of it.
- 08:41But we do know that it is not as transmittable as,
- 08:44let's say, measles, which is one
- 08:46of the most transmittable common diseases
- 08:50which has this R0 Number of 12 to 15.
- 08:53In certain outbreaks, it has gone up to 17.
- 08:56Ebola had this number of two.
- 08:58And this is, the novel coronavirus is comparable to SARS.
- 09:03It's more than the flu.
- 09:05And so, this is some perspective to keep in mind,
- 09:08with a caveat that our information is evolving.
- 09:11We certainly know a lot more about this virus
- 09:14than we knew a couple of weeks ago.
- 09:16But our understanding is evolving and so keep that in mind.
- 09:20Now, this is a natural phenomenon in all outbreaks
- 09:25that are emerging.
- 09:27So what can we do?
- 09:29So I have thought about it a little bit
- 09:30in terms of the big picture policy response,
- 09:33and we will be, so the implicit focus will be,
- 09:36the response, from an academic and research perspective
- 09:40for the rest of the panel.
- 09:42But one of the things, those of you who don't know,
- 09:44that the writers have
- 09:45very little control over the headlines.
- 09:50So there's separate editors who do the headlines.
- 09:52So my op-ed was a little bit more nuanced
- 09:55than the headline would suggest.
- 09:57But we certainly have, I certainly didn't go,
- 10:02for a call and response kind of a framework.
- 10:04"Are we ready?"
- 10:05"No."
- 10:06(audience laughing)
- 10:07But we did talk about certain gaps.
- 10:13First of all, what I postulated was, and this was,
- 10:18I wrote this a few hours
- 10:19after the first case were identified.
- 10:21The government hadn't formulated its response.
- 10:25So some of us were concerned about the response
- 10:30being handled by the political leadership.
- 10:34Look, it's not an unreasonable thing
- 10:35to say that our elected leaders who we elect in a democracy
- 10:39could be at the helm of a major emergency.
- 10:43But this is slightly different
- 10:44and it should vary from pathogen to pathogen
- 10:47and emergency to emergency, and here's the reason why.
- 10:51When you have an outbreak with substantial uncertainty,
- 10:55we should acknowledge that uncertainty,
- 10:57but the decision-making process should be structured
- 11:00in a way that the assimilation of ever-changing
- 11:03and ever-evolving information, and the decision-making
- 11:07should be very proximal
- 11:09and ideally led by the same set of people,
- 11:12who have the detailed, nuanced knowledge,
- 11:15intuitively of these things.
- 11:18They should be calling the shots.
- 11:19And who are those people?
- 11:20Fortunately, those in this country
- 11:24who are leading our major public health agencies,
- 11:27the NIH, the CDC, FDA, even the HHS,
- 11:32various entities within the HHS,
- 11:34are mainstream, well-respected scientists
- 11:37or public health professionals.
- 11:38And so, rather than sort of having this outbreak,
- 11:42irrespective of the political perspective,
- 11:44in this kind of a situation,
- 11:46being handled at the White House level, for example,
- 11:49it would be best for the agency heads to tackle this.
- 11:54So similarly, let the scientists
- 11:56and public health professionals lead.
- 11:58But, look, it is hard, it's highly unsatisfying.
- 12:03I was on an AMA Reddit half an hour before I came here,
- 12:10where a lot of questions, it's easy to speculate.
- 12:13It's very tempting to say, provide certainty.
- 12:18We certainly know a lot about this outbreak than before.
- 12:22But we owe it to the general public
- 12:24to convey what we don't know.
- 12:26But also, what is knowable and what will never be known.
- 12:31And so, therefore, yes, saying that what
- 12:34is happening right now, you shouldn't be walking around
- 12:39in a spacesuit on College Street,
- 12:42it is reasonable to say that.
- 12:44But on the other hand,
- 12:45we don't know the future risk of this outbreak.
- 12:49We have some things to go by,
- 12:50and we'll flesh that out a little bit in more nuance.
- 12:53So don't provide false assurances, don't alarm, certainly.
- 12:57And the other thing that has happened,
- 12:59as look universities have a unique space in our society.
- 13:04Which is we are the guardians of evidence.
- 13:08Lux et Veritas is not an accident.
- 13:11And when we are guardians of evidence,
- 13:16we should think about not just what knowledge
- 13:19is being generated and how it's being implemented,
- 13:22but the quality of that evidence.
- 13:24And so, the preprint server movement,
- 13:26where open science requires
- 13:28and nudges us to share our data and our academic output
- 13:33very quickly on these preprint servers without peer review.
- 13:37Overall, is a really positive development
- 13:39when it comes to speed of sharing knowledge
- 13:42and can serve us really well.
- 13:44The genomes were posted very quickly and very robustly,
- 13:48in the sense that, in terms of the number,
- 13:50obviously there was a proportion there was a lag.
- 13:52But we should also be careful about
- 13:56how valid that information is.
- 14:00So one way to thread that needle,
- 14:01and there have been incidents that things
- 14:03have been retracted, even in the New England Journal.
- 14:05So it's not just the new preprint servers
- 14:08that have been vulnerable.
- 14:09There have been other things on preprint servers
- 14:10that have been revised, et cetera,
- 14:12and people have changed their perceptions
- 14:14around the outbreak based on that.
- 14:16So one of the proposals I discussed there
- 14:20is to have a preplanned rapid peer review system
- 14:23that is already set up to evaluate information
- 14:28on a quick turnaround basis.
- 14:30I'm not going to go into the details right now.
- 14:33But just to remind you of the response,
- 14:35this is a public health emergency of international concern
- 14:39declared by the WHO.
- 14:40There have been travel restrictions, et cetera,
- 14:43and there have been quarantine,
- 14:46various measures akin to quarantine
- 14:47that have been implemented.
- 14:49We will discuss the matter to the value
- 14:51and sort of nuances of these responses in a little while.
- 14:55These are a couple of things WHO recommends
- 14:57in terms of preventive measures:
- 15:00covering mouth and nose when you're coughing and sneezing,
- 15:02if you're using tissues
- 15:04into closed bin immediately after use,
- 15:06cleans hands, hand-washing is a very important
- 15:09preventive measure, it's not a panacea,
- 15:12that's gonna take care of all our wolves
- 15:14when it comes to respiratory disease,
- 15:16but it is something that you can do now.
- 15:19It is evidence-based and this is something we can do now
- 15:23without any further technological development.
- 15:25And then, there are certain recommendations,
- 15:27without going into details, on the WHO side
- 15:28in terms of staying healthy while traveling.
- 15:31So I'll pause here and I will then introduce
- 15:35our panelists one by one.
- 15:37But before I do that, I wanna thank one of my postdocs
- 15:40who helped with some of those slides,
- 15:42Amyn Malik, and I already thanked Albert and others
- 15:45for helping organize this session.
- 15:49I'm gonna call the panelists in alphabetical order.
- 15:53The first one is Ellen Foxman.
- 15:56She's an assistant professor of lab medicine and immunology
- 15:59at the Yale School of Medicine.
- 16:01Her research focuses on understanding the natural mechanisms
- 16:05that protect the airway from respiratory viruses.
- 16:08And you can see how that is relevant
- 16:10to what we are talking about right now.
- 16:12And one of the interesting things that she's working on
- 16:15is rapid diagnostics for these kinds of emerging diseases
- 16:19for mass screening.
- 16:20So that straddles individual and public health response.
- 16:23And that's one of my favorite kinds of responses.
- 16:27The second panelist is Gregg Gonzalez.
- 16:33He's an assistant professor of epidemiology
- 16:36and associate adjunct professor of law
- 16:38of Yale Law School, and he's the co-director
- 16:41of the Yale Global Health Justice Partnership.
- 16:43So he has two homes, Yale School of Public Health
- 16:46and the Law School.
- 16:50And he's a perfect example of an activist scientist.
- 16:57He's a solid activist, a very passionate activist,
- 17:00he has the fire in the belly that we all felt
- 17:02on our first day of grad school.
- 17:03(audience laughing)
- 17:05Some of us get jaded,
- 17:07others stay enthusiastic and passionate.
- 17:10And he's also a top-notch scientist
- 17:13and models impact of decisions and operation
- 17:18instead of using quantitative techniques,
- 17:22which are really fascinating.
- 17:24The third panelist is Nathan Grubaugh.
- 17:28He's also an assistant professor of epidemiology
- 17:30of microbial diseases at the Yale School of Public Health,
- 17:33and he has done some very interesting work
- 17:36on genetic epidemiology and has be co-curating
- 17:39with his colleagues these viral genomes
- 17:42that have been posted or have been shared,
- 17:46and sort of creating this, if you will,
- 17:50the map of this genome as it evolves.
- 17:52And this is realtime public health
- 17:55that takes advantage of important immediate
- 18:00information sharing and brings it together for, hopefully,
- 18:06decision-making and response to an emerging threat.
- 18:09Then, we have Lisa Sanders.
- 18:10Dr. Sanders is a clinical educator
- 18:13in Internal Medicine and she's a primary care provider
- 18:16and an Emmy Award-winning producer of CBS News,
- 18:21as well as an author.
- 18:22And the other thing that I like, as a House fan,
- 18:27she was one of the inspirations for House.
- 18:30Is that correct?
- 18:31- [Lisa] My column, nothing personal, I'm way nicer.
- 18:34(audience laughing)
- 18:35- [Saad] Because I was trying to look for the resemblance
- 18:36with Hugh Laurie.
- 18:37- [Lisa] Sometimes, I win.
- 18:39(audience laughing)
- 18:42- [Saad] And then, our last panelist is David Vlahov.
- 18:47He's the PhD program director and professor
- 18:49at the Yale School of Nursing,
- 18:50and then he also has a joint appointment
- 18:54with Epi here in the School of Public Health.
- 18:58He was involved and he did some very fascinating work
- 19:01in early 2000 when SARS broke and anthrax happened
- 19:05on the response of healthcare providers
- 19:08or the public health workforce,
- 19:09including school nurses, et cetera,
- 19:11who can be the tip of the spear of a mass response,
- 19:15and was involved from that perspective.
- 19:18But also, as a professor of nursing,
- 19:20has thought about and would provide his expertise
- 19:23on some of the healthcare
- 19:25and workforce decisions, et cetera.
- 19:28There are a couple of people who are in the audience
- 19:30who are not official panelists,
- 19:33but I may sort of put them on the spot.
- 19:37One is Dr. Paul Genecin.
- 19:39He's the director of Yale Health.
- 19:41So if there are any questions that come
- 19:43from that perspective, I will point to you.
- 19:46And Albert Ko, who's an overall smart person,
- 19:50(audience laughing)
- 19:51but also, in all of it,
- 19:53has long-standing links with Chinese colleagues.
- 19:56But, equally importantly, he's involved
- 19:59with a WHO working group developing interventions
- 20:04and evaluating interventions, more importantly,
- 20:07developing a common protocol so that we are not
- 20:11have a different playbook for developing counter-measures
- 20:17against this outbreak.
- 20:19So with that, I'll switch to the question and answer phase
- 20:23of this forum.
- 20:30So my first question will be from Nate,
- 20:37"So where did this virus come from?"
- 20:39And I think our best bet to figure this out
- 20:42is not to send Hugh Laurie and investigate,
- 20:46but to look at the genetic data and look at other viruses,
- 20:50et cetera, that could tell something about that.
- 20:53Could you elaborate a little bit on that.
- 20:54- [Nate] Yeah, sure, thank you.
- 20:56First I would just like to say that it's really great
- 20:57to see so many students in the audience,
- 21:00so many people that are interested
- 21:01from a lot of different backgrounds.
- 21:03So the question really gets at something
- 21:06that I'm very interested in with outbreaks
- 21:08and that is misinformation.
- 21:11So, if any of you are on Twitter
- 21:14or are reading some columns,
- 21:15maybe you see a lot of misinformation about the origins
- 21:18of this outbreak.
- 21:19For a second telling you this is not a deliberate release
- 21:23from a laboratory.
- 21:24Some of the evidence that people present for that
- 21:28is a paper that did some, I'm gonna say, "shoddy" analysis,
- 21:32to say that there is elements within the coronavirus genome
- 21:36that had an, "uncanny resemblance to HIV."
- 21:39And therefore it was man-made and released from a lab
- 21:42that they say there's a high-containment virology lab
- 21:47in Wuhan which is actually perfect
- 21:49for being able to respond to these events
- 21:51but then people are suggesting that the virus was manmade
- 21:54and came from this lab.
- 21:55That is absolutely not true,
- 21:56there is no evidence to actually say that,
- 21:58and the analysis was faulty.
- 22:00Where this actually came from is like with Saad's slide,
- 22:03is the group of viruses
- 22:05that this virus belongs to are beta-corona viruses.
- 22:07And they're ancient origins are in bats,
- 22:09there's some 200 different known species
- 22:13of beta-corona viruses in bats,
- 22:14and from what we know there are seven of these viruses
- 22:20that have spilled over into human populations
- 22:22that caused outbreaks.
- 22:23Four of 'em cause common cold,
- 22:25they're right here in New Haven.
- 22:27One of 'em is SARS, one of 'em is MERS,
- 22:29and one of 'em is now this novel coronavirus.
- 22:32So the question really is then,
- 22:34looking at these genomes and looking at this data
- 22:36of when and where did this happen?
- 22:40So the when part of it, if we look at all the genetic data
- 22:42that we have, we can estimate that the origins
- 22:45of the outbreak was about early December,
- 22:49maybe late November.
- 22:50And there are some questions about whether
- 22:53this came directly from a live market that was in Wuhan,
- 22:57it's sort of uncertain if that is actually the case,
- 23:00the most epidemiological evidence would suggest that.
- 23:03But it certainly came from a mammal of sort,
- 23:06so beta-corona viruses infect mammals
- 23:09and this gets into another point of misinformation out there
- 23:11that maybe this was a snake virus,
- 23:13or maybe this actually spilled over from fish.
- 23:15We don't know of any of these viruses that have ever
- 23:17infected anything other than mammals.
- 23:20So what exactly that intermediate host was,
- 23:23if there was an intermediate host,
- 23:24before we had a human outbreak is sort of unknown.
- 23:29- [Saad] So that brings me to the question about
- 23:32the viral pathogenesis, so Ellen, do you mind elaborating
- 23:37a little bit on that part of how the virus effects our cells
- 23:42and us as humans?
- 23:44- [Ellen] Yeah, sure.
- 23:46Hello everyone, it's great to be here.
- 23:47So my life study's respiratory viruses
- 23:52and there's a lot of those as we were all familiar with
- 23:56the common cold, the flu, and these viruses that we get,
- 23:59year after year.
- 24:00And so I thought I'd talk about this virus
- 24:02in the context of that, what are similarities
- 24:05and what are some differences?
- 24:06So as many of you probably know,
- 24:09the way a virus causes illness is it is able to enter a cell
- 24:13or several cells of your body and hijack those cells
- 24:16and basically turn those cells into factories
- 24:18for making more virus, which can be damaging to the cells.
- 24:22But then your immune system realizes that's happening
- 24:26and comes to that area of the body to fight it,
- 24:29fight the virus and get rid of it.
- 24:31And wherever that battle is going on
- 24:32is where you get the symptoms.
- 24:33So if you get the common cold virus in your nose,
- 24:36the immune system's fighting it in your nose,
- 24:37you get the symptoms of the runny nose and so forth.
- 24:41If that battle's going on in the lungs,
- 24:42then you're going to get lung symptoms,
- 24:44breathing problems and whatnot,
- 24:46the things we associate with pneumonia.
- 24:49So this virus can do both of those things.
- 24:52It can effect the nose or it can effect the lungs or both.
- 24:56So you might ask, "Well, why are we more concerned
- 24:59"about this, we get these viruses every year,
- 25:02"they're going on in New Haven right now.
- 25:05"We've got lots of other respiratory viruses."
- 25:07And the main thing is, is the fact that it's new
- 25:11to the human population.
- 25:13So as I'm sure many of you are also familiar with,
- 25:16is the idea that when our body fights a virus
- 25:19there's a memory immune response that's formed,
- 25:21that makes it so if we see a virus,
- 25:23that virus or a similar virus again,
- 25:26our body is much better at blocking it
- 25:28before it even gets into cells.
- 25:29So that's always the concern about a new virus
- 25:33is that none of us have
- 25:35that pre-existing immune defense up and going.
- 25:39And that makes it potentially easier for the virus to spread
- 25:41from person-to-person and also if it gets into your body,
- 25:45you don't have that first line of defense
- 25:47that could maybe prevent disease
- 25:49as well as if you had seen the virus before.
- 25:51And that's why, like a new virus,
- 25:53is always a cause to be alert, it's a cause to be vigilant.
- 25:58Just because it's new,
- 25:59doesn't mean it's worse than other viruses that we know,
- 26:03that we're familiar with but it means there's a potential
- 26:06and that's why there's a reason
- 26:08for the heightened vigilance about it.
- 26:11- [Saad] That's a very important point to remember,
- 26:14that just because it's new, doesn't necessarily mean
- 26:20it's worse, unless it's a disaster movie.
- 26:22(audience laughs)
- 26:24You get that, it's not-
- 26:25- [Ellen] Yeah, we just don't know
- 26:25a lot of those things yet.
- 26:28- [Saad] Yeah, exactly.
- 26:29And so Lisa, you're practically a doc
- 26:32and tell us a little bit about what preventive measures
- 26:36we can take now and perhaps if the outbreak expands
- 26:41in the community.
- 26:44- [Lisa] Well, it seems now, we all know what to do,
- 26:47hand-washing and coughing into your elbow
- 26:52and things like that.
- 26:54Not probably getting too close to people
- 26:59who have obvious infections, giving them their space,
- 27:03there's probably pass-through fomites
- 27:06or other kinds of respiratory-borne particles.
- 27:12So I don't think there's anything particularly wild
- 27:15that we can do, I'm not sure that,
- 27:17certainly if you had a cold
- 27:19perhaps it might help if you wore a mask.
- 27:21But certainly there's no evidence that wearing a mask
- 27:24is going to keep you from getting it.
- 27:26Nor does there seem like there're very many people who
- 27:29have it now to get it from.
- 27:31So I think having ordinary levels of precaution makes sense.
- 27:36I mean, I assure you,
- 27:38most people don't wash their hands nearly enough.
- 27:41So if people just washed their hands just a little bit more,
- 27:44it would probably go a long way.
- 27:47- [Saad] Yeah, that's certainly aligned with
- 27:48CDC recommendations and specifically,
- 27:52at least at this point,
- 27:52CDC doesn't recommend wearing face masks.
- 27:56It's probably perhaps one of the reasons people wear them
- 28:00is for self-efficacy, they want to feel in charge.
- 28:04It's a situation of helplessness,
- 28:07when there is a lot of uncertainty.
- 28:09So perhaps those of us who, there's a few who work
- 28:12on health behavior and communications,
- 28:14perhaps we should have a message of self-efficacy
- 28:16in the form of saying, "You can wash hands."
- 28:17Which is not going to take care of everything,
- 28:21you can practice some level of social distancing
- 28:25without being paranoid about this,
- 28:28especially when you have someone infected,
- 28:30social distancing doesn't mean that start discriminating
- 28:32against people willy-nilly, it means if you have someone,
- 28:37if you are specifically in that kind of a situation,
- 28:39you take some of these precautions.
- 28:42And also, the original prevention to public health response
- 28:46David, do you have any thoughts in terms of the response
- 28:50at the mass level and some of the things
- 28:53that you were involved with earlier on,
- 28:57in previous similar outbreaks?
- 28:59And the second part of that question
- 29:01of some of the things that have been employed
- 29:03by various countries, including China, including the US,
- 29:06and some of the others.
- 29:08- [Assistant] Here you go, sir.
- 29:09- [David] Oh, okay (laughs).
- 29:12Thank you for the question.
- 29:16In terms of what's going on in China,
- 29:20there's quite a bit of discussion about whether quarantine
- 29:27makes things better or makes things worse.
- 29:30And the idea of having people
- 29:33that are separated and protected,
- 29:36seems like it would be a good idea,
- 29:39but it also has a stigmatizing effect
- 29:43where people can under report, go underground, if you will.
- 29:49And if we take the example of Ebola,
- 29:52which again's a very different,
- 29:54it's an analogy that doesn't work at a lot of levels,
- 29:58but again just that stigma of being confined
- 30:04and not trusting in a particular environment,
- 30:09there's a lot of discomfort and anger and acting out
- 30:18that can happen with that.
- 30:21So what's the process that can be a middle ground.
- 30:27And the approach that I think seems better,
- 30:32although you have to look at what is the local situation,
- 30:35what are cultural considerations that go with that,
- 30:41are to be able to have a conversation with people,
- 30:45in terms of what is your likelihood of having been exposed
- 30:50given what we know
- 30:52and taking that person to have the individual responsibility
- 30:57for staying at home, for example, right?
- 31:01Secluding oneself for a period of time,
- 31:05that's a social contract that happens,
- 31:09and for many people that seems very reasonable
- 31:13and there're going to be others
- 31:15that may need a little bit more assistance in that area.
- 31:21So I think that's one of the larger issues that comes up
- 31:25and has certainly been in the news,
- 31:28is quarantine or cordon sanitaire, right?
- 31:33What are the different levels of protection one can have?
- 31:38Now another part of the question is
- 31:42what is a public health response?
- 31:46And Robin Gershon and Chris Korechi were doing a study
- 31:51of nurse preparedness in New York City
- 31:56and found that if there was some sort of disaster
- 32:00that was about to happen, what barrier,
- 32:03how many of you would have at least one barrier,
- 32:06that would stop you from showing up to work, whatever?
- 32:09So turns out it was 90%, like a childcare,
- 32:14all those different issues and then, it was not by design,
- 32:20but the Anthrax, hit New York City and they followed up
- 32:23and they found out that every single person,
- 32:26every single one of the nurses, showed up to work,
- 32:28and did what their job was, right?
- 32:32So part of it is recognizing that people will rise up
- 32:38to what that challenge is,
- 32:40what their professional responsibilities are,
- 32:43and part of that also is having the education and support
- 32:50to be able to do that.
- 32:51So I'll pause, 'cause I could keep going, I'll pause.
- 32:55(audience laughs)
- 32:56- [Saad] Yeah. No, so very insightful.
- 32:58So you mentioned quarantine
- 33:00and Gregg I want to sort of switch to you,
- 33:02there was some really interesting work,
- 33:04I wasn't here in New Haven in the area at that time,
- 33:08but there was Ebola-related quarantine, as I understand,
- 33:12in the area and even as an outsider,
- 33:15as someone who looks at these issues,
- 33:18I found Yale Law School's and some of the people who were
- 33:23involved in the Global Health Justice Partnership,
- 33:24collaborated with the ACLU,
- 33:26on a report that came out of that experience.
- 33:29Which is a very, very helpful, very pragmatic tool,
- 33:33that a lot of public health practitioners
- 33:36should pay attention to.
- 33:37Could you elaborate, in terms of, if we quarantine
- 33:40or whatever the parameters of quarantine should be?
- 33:43And if we do that, how should that look like?
- 33:46- [Gregg] So if you were here in 2014, 2015,
- 33:52in wake of the Ebola epidemic in West Africa,
- 33:55several governors across the country,
- 33:58decided to quarantine individuals returning from,
- 34:01West Africa healthcare workers, in absence of symptoms,
- 34:07confine them under quarantine.
- 34:08Including two Yale students,
- 34:10who were not infected with Ebola,
- 34:12and including a West African family from Westhaven,
- 34:15who were not infected with Ebola,
- 34:17this was done by former Governor Dan Malloy.
- 34:20We're still in a lawsuit,
- 34:23the law school's immigration clinic is partnering with us
- 34:27in a suit against the State of Connecticut
- 34:28against these quarantines,
- 34:29but we wrote a paper with the ACLU
- 34:33and Doctors Without Borders that talked about
- 34:35what would happen, the epidemiological and the legal
- 34:39implications of the Ebola quarantine on healthcare workers
- 34:42in the wake of the Ebola epidemic.
- 34:44And Dan Bausch who was one of our evening speakers
- 34:48two weeks ago was one of the scientific advisors on that
- 34:50(murmurs) illness and helped out.
- 34:51You can see the report on the GHJP website
- 34:54at the Yale Law School, but the back of the report
- 34:57has recommendations about what happens next time?
- 35:00Guess what, it's next time.
- 35:02A couple of things to remember,
- 35:04one is to use the least restrictive measures possible,
- 35:07so not to overreact.
- 35:08So in the case of the Ebola epidemic the quarantines
- 35:11were absolutely unnecessary, unjustified.
- 35:14As David is saying, there may be self-isolation
- 35:17and staying at home if you feel sick
- 35:21or quarantined if necessary, but really to use
- 35:24the least restrictive measures for a start,
- 35:28rather than sort of going full-steam ahead for quarantines.
- 35:31The other thing is to ensure robust procedural protections.
- 35:34You have rights, under the US constitution,
- 35:37to bodily autonomy and due process.
- 35:40So when our students were put into quarantine,
- 35:43we could appeal their cases immediately to the courts,
- 35:49but it was a 14 day quarantine and we ended up saying,
- 35:52afterwards because the time-period was too short.
- 35:56But you do have robust- you do have rights
- 35:58under the constitution to due process.
- 36:01Kaci Hickox was a nurse, with MSF, who came back to the US
- 36:05and was quarantined by Governor Christie,
- 36:07a republican in New Jersey,
- 36:10her quarantine was overturned by a judge in Maine,
- 36:12who said it was epidemiologically unjustified.
- 36:14So in one case the law worked out.
- 36:17The other thing is ensure humane conditions of confinement.
- 36:22Now I saw on the news today that China is thinking about
- 36:25quarantining or taking all the infected people,
- 36:29in Wuhan and other places,
- 36:30and putting them into quarantine camps.
- 36:35What are the conditions going to be like for them?
- 36:37Are they gonna get adequate health care?
- 36:38Is there gonna be adequate infection control?
- 36:42We're thinking about the risks
- 36:43to us here in the United States,
- 36:44but think of the thousands of Chinese patients
- 36:47with coronavirus now whose health status
- 36:52is going to be put into precarious position
- 36:55if they are isolated in these facilities
- 36:56that we have no idea of who's overseeing their quality
- 37:00and their ability to prevent onward transmission
- 37:05from these sites.
- 37:06So there's lots of things we can do,
- 37:07I'm not gonna go through all the recommendations,
- 37:08but follow the science, as Saad said.
- 37:12Follow the evidence.
- 37:15If you hear the words, "abundance of caution," beware,
- 37:19because it means, "Damn the evidence and we're gonna do
- 37:23"what we want to do."
- 37:24And that's what Governor Daniel Malloy,
- 37:25Governor Chris Christie, and Governor Andrew Cuomo did
- 37:28in 2014, 2015, which was bi-partisan stupidity.
- 37:31(audience laughs)
- 37:33- [Saad] On that note of bi-partisan Kumbaya, I guess
- 37:38(audience laughs)
- 37:40So I want to switch to a lot of those decisions were made
- 37:43in a communications environment, in a public,
- 37:45in the view of an interesting, to say the least,
- 37:50public discourse.
- 37:52So, Lisa, as someone who has been involved, as an author,
- 37:55as a producer, obviously as a physician,
- 37:59on top of all of this, what do you think,
- 38:02what is your initial impression of what is happening now?
- 38:07What are some of the nuances,
- 38:08what are some of the adequacies,
- 38:09what are the things that we should have learned
- 38:12from previously that we could do better?
- 38:16- [Lisa] Well, if you, I don't know how accurate
- 38:18a representation of the country Twitter is,
- 38:22but you don't have to look very deep in Twitter
- 38:24to start seeing real crazy about this proliferate.
- 38:31And to some degree I think that's completely natural
- 38:37because of the disconnect between the messaging that we have
- 38:41"You're much more at risk of the flu, just wash your hands,
- 38:45"don't worry about it, it's going to be okay."
- 38:48Versus closing the country off
- 38:50to people from different countries, who've been to China,
- 38:55imposing quarantine, sending people to concentration camps
- 39:03when they're diseased.
- 39:04I mean, that suggests a level of concern,
- 39:08that doesn't really match what we're told to do, right?
- 39:12So we're told to calm down and yet everybody
- 39:16in the government seems to be extremely excited.
- 39:19And nobody's really trying to make that connection
- 39:22and when you have big gaps like that,
- 39:25it's inevitable that crazy creeps in
- 39:29because people are worried and that's how people express it.
- 39:33I think that we need to acknowledge that we have to
- 39:37try to make sure that nothing bad happens,
- 39:41while saying the risk right now seems limited,
- 39:46and acknowledge that we don't know what the future holds.
- 39:48I mean, I think that those are the reasonable steps.
- 39:51But this kind of "pooh-poohing" concern, of course,
- 39:55makes everybody crazy and really worried
- 39:59and I think it's completely natural.
- 40:03As journalists, of course, we need the snappy headline,
- 40:08it's essential, I mean, maybe the New York Times
- 40:11doesn't need a snappy headline,
- 40:13although I think they have been tempted
- 40:15by that once or twice, but certainly other publications
- 40:19need that, television needs that.
- 40:22I mean, people are, this is a competitive environment.
- 40:25So some of that is understandable,
- 40:27I don't know that it's forgivable.
- 40:30But as public health people, we have to step in
- 40:33and try to make it make sense to the people around us.
- 40:39We can't depend on the media necessarily to do it.
- 40:42- [Saad] So the frontline of this response, in this country,
- 40:47because of the way certain powers are given to the state
- 40:51and local health departments, a lot of people don't realize
- 40:55that yes, CDC provides technical guidance,
- 40:58but actual action, in terms of outbreak prevention
- 41:02and control, on the ground happens
- 41:04at the state and local health departments.
- 41:06Over the past 20 years, there has been a lot of investment.
- 41:10The investment in terms of resources have stalled.
- 41:16Should we be reassured, in one way, by the headstart
- 41:22we have had, since SARS and Anthrax and the 2009 epidemic
- 41:27and/or should we be concerned because of the cuts
- 41:32that the public health system has seen over the last,
- 41:37at least, six, seven years?
- 41:39So any thoughts on that, David?
- 41:43- [David] I'm not sure except, how best to start on that.
- 41:50You know it's a crisis like this that can be a stimulus
- 41:55to get the public health funding.
- 41:57I mean, we certainly saw that in earlier crises,
- 42:00it may be delayed, but I think there's a opportunity here
- 42:06to say we've gotta take the public health preparedness
- 42:10very seriously and to generate the resources
- 42:15to be able to respond to this.
- 42:17- [Saad] But isn't that, usually vanished after,
- 42:19sort of we get this bolus, this sugar rush of investment
- 42:23in global health and then we have
- 42:26this seven years of crankiness
- 42:28after that sugar rush dies down.
- 42:30In terms of where we, the public health system,
- 42:32after building up, having this surge,
- 42:37then suffers from these consequences.
- 42:41Any thoughts on a sustainable way
- 42:45of investing in public health this way?
- 42:47I know Sten, Development had a very good op-ed,
- 42:51in terms of the global health investment
- 42:53and not having these boom, bust cycles
- 42:55and sustaining the infrastructure.
- 42:57But domestically speaking, sort of any thoughts
- 43:01on how to maintain that infrastructure that doesn't
- 43:02go through these cycles?
- 43:07Sten, do you want to contribute?
- 43:09- [Sten] Sure.
- 43:13The reality is that public health is faced
- 43:19with an inherent challenge.
- 43:22It's hard to convince policy-makers to pay you
- 43:26to do something to prevent something from happening.
- 43:28It's much more intuitive to invest in hospitals,
- 43:34to care for the ill,
- 43:35than it is in public health infrastructure
- 43:37to prevent the illness to begin with.
- 43:39So that is part of the theme I think this evening
- 43:42of all the panelists,
- 43:43that we're up against tremendous communications challenges.
- 43:48How do we advocate for infrastructures
- 43:52for disease prevention, for rapid response?
- 43:57To be prepared for something that might or might not happen?
- 44:00And there's so many compelling demands,
- 44:04in a developing country you advocate for public health
- 44:08and you're up against the minister of defense,
- 44:11you're up against the minister of tourism,
- 44:13you're up against the minister of education.
- 44:16Where we have more resources and high-income settings,
- 44:20it's almost equally challenging.
- 44:23The NIH budget is in the neighborhood of
- 44:29$33 billion dollars a year
- 44:31and the CDC budget is a fifth of that.
- 44:33So people understand disease, research to treat disease,
- 44:35tremendous investments in clinical trials,
- 44:40the prevention budget is far more modest.
- 44:44So I think it's part of our duty,
- 44:46here in the school of public health,
- 44:47to work more diligently on how to communicate
- 44:51with lay audiences about public health and prevention.
- 44:55How to communicate with policy makers
- 44:58so that they appreciate that an ounce of prevention
- 45:02is worth a pound of cure,
- 45:04which I suspect our grandmothers told us.
- 45:07And at the end of the day, integrating acute care settings,
- 45:13with chronic care maintenance,
- 45:18as with the HIV investments in Africa,
- 45:21where a tunnel vision approach,
- 45:23that these are for HIV, HIV and nothing but HIV,
- 45:27when people may be dying of untreated hypertension,
- 45:30where there may be an Ebola virus epidemic around the corner
- 45:33in which those infrastructures could be helpful,
- 45:36a coronavirus epidemic.
- 45:38I think we need to be broader in our thinking,
- 45:41less siloed and more attentive to how infrastructures
- 45:46can be very potent, they can serve a function today,
- 45:51for an investment today,
- 45:52but keeping in mind that there may be
- 45:55an investment in near future,
- 45:57for which these infrastructures can be highly valued.
- 46:03Ultimately, that's a challenge we're facing.
- 46:06I know that the Bloomberg philanthropies are investing
- 46:08in precisely that with Tom Friedman's initiative
- 46:14in New York City and the whole philosophy of that initiative
- 46:17is chronic disease care, upgrading that care globally,
- 46:21but having each chronic disease investment, be prepared
- 46:26for acute responses to outbreaks
- 46:28and I think that's a very wise philosophy.
- 46:31- [Saad] That's a really good point.
- 46:33In terms of, coming back to a little bit more science,
- 46:37and one of the misconceptions
- 46:39and one of the more frequent questions
- 46:40some of us get asked by the press is,
- 46:42"Is this virus mutating?"
- 46:44And that's such a general question,
- 46:45I'm not gonna go into the details of
- 46:47why is that a non-specific question because we have someone
- 46:52who knows a lot more about it than I do, so Nate,
- 46:54would you like to elaborate on the various layers
- 46:58of that question?
- 46:59- [Nate] So this is one of my favorite topics
- 47:01of misinformation during outbreaks
- 47:04and the answer is, "Of course, it's mutating."
- 47:06But go back a second.
- 47:08So mutations sort of conjure up these inherent fears
- 47:14of something unexpected and some major change,
- 47:18think of American pop culture - X-Men, right?
- 47:22These mutant humans have these extraordinary abilities.
- 47:25You think about, have your ever read "Andromeda Strain"
- 47:28or watched the movie "Outbreak"?
- 47:30As soon as a mutation is introduced into the picture,
- 47:33something new is happening.
- 47:34So of course, the people that grew up on this,
- 47:39when you hear the word mutation, right,
- 47:41this is what you're thinking about.
- 47:42You're thinking about these crazy changes that can happen,
- 47:45not about the fundamental evolutionary processes.
- 47:49So every time a virus replicates, when it copies its genome
- 47:55on average about one mutation is introduced.
- 47:57And most of these mutations don't do anything to the virus,
- 48:01some of 'em make the virus worse than their loss,
- 48:03and some of them provide a benefit.
- 48:05But what we're actually thinking about, I think,
- 48:07when people ask about mutations
- 48:09are actually natural selection.
- 48:11So are these viruses becoming better adapted at something.
- 48:16So I think it's a perfectly reasonable question to ask,
- 48:19"Is this novel coronavirus, adapting to humans?"
- 48:22So during the Ebola epidemic, in West Africa, we found
- 48:26that early on in the outbreak,
- 48:30there was a mutation that appeared
- 48:31and through a lot of experiments and everything,
- 48:34we found that it eventually dominated the outbreak.
- 48:36And it looked to be a human adaptation.
- 48:38But when we look at the epidemiological evidence,
- 48:40so that people who are infected with this mutation,
- 48:43or with not, there wasn't a difference in the death rates,
- 48:46there wasn't a difference in how much virus you had.
- 48:49It was a human adaptation that didn't really have a major
- 48:51epidemiological impact, the same with SARS.
- 48:55SARS, after it was introduced,
- 48:57we found these changes that happened
- 48:58that looked like they were human adaptations,
- 49:01but when you look back at the data
- 49:02you can't actually determine if this had any major impact
- 49:06on the overall epidemic.
- 49:09So could this novel coronavirus
- 49:12adapt better to infect humans?
- 49:13Sure, possibly could.
- 49:15Will it have a major impact on the epidemic?
- 49:17Will it cause more deaths?
- 49:19There's not really any evidence to suggest that.
- 49:22- [Saad] So my last question of this phase,
- 49:24before I open up, is from Ellen,
- 49:27and I want you to talk about a little bit about diagnostics.
- 49:32So our ability to detect this,
- 49:33especially from the perspective of being Global Health,
- 49:36you always think about inequities.
- 49:40For example, in Africa, one of the questions is,
- 49:43the fact that we haven't detected a lot of cases,
- 49:47is because is it the absence of the virus
- 49:53or the absence of detection, et cetera?
- 49:54So could you talk a little bit about our ability
- 49:56to have these diagnostics and it's implications
- 49:58for an equitable response through knowing the burden
- 50:03and the ability from a scientific perspective,
- 50:06to detect these viruses in populations.
- 50:09- [Ellen] Okay, sure.
- 50:11(alarm rings)
- 50:12So one thing that was really quite amazing
- 50:14about this outbreak compared to other ones
- 50:17is how quickly the actual genome sequence
- 50:20of the virus was online.
- 50:22It took about a week, I mean, it was amazing
- 50:25and so advance in technology,
- 50:29we all know that it's much easier to sequence genes
- 50:35than it used to be,
- 50:36but this is really a great example of that,
- 50:38where as soon as that outbreak was recognized,
- 50:42that scientists were able to actually,
- 50:46right from the patient sample,
- 50:48get the whole sequence of the virus.
- 50:50In the past you had to try to grow it
- 50:52and there was a many steps.
- 50:53And that was really an example of the application
- 50:55of a pretty expensive technology actually,
- 50:58but in a way that's gonna benefit
- 51:00a lot of people very quickly.
- 51:01As far as diagnostic tests, that's discovery,
- 51:06that's virus discovery and this has really been quite
- 51:09like a poster-child for amazing infrastructure
- 51:13for virus discovery.
- 51:16As far as diagnostics, having that genome sequence
- 51:20online immediately, the way that we detect viruses,
- 51:24here in our hospital right here in Yale,
- 51:26is often by doing a detection of the snippet of the genome.
- 51:29And having that genome sequenced that quickly means
- 51:32you can quickly make a diagnostic test.
- 51:34Which the CDC has done.
- 51:37But then the other issue comes of
- 51:41if you do a diagnostic test enough times,
- 51:44on a population that doesn't have the disease,
- 51:47you're gonna get some false positives.
- 51:49Any positive would be a false positive.
- 51:50So right now what's happening is, there's a lot of criteria,
- 51:55before people will be tested by the CDC,
- 51:59that they actually have a chance of having the virus,
- 52:02before they will be tested in the US.
- 52:05As far as around the world, I mean, these kinds of tests
- 52:10are not super cheap.
- 52:11These PCR based tests, it's a little bit complicated,
- 52:14you need a special machine,
- 52:17you need people who are trained to perform the test.
- 52:24So for all those reasons, it's not something that you can
- 52:27quickly and cheaply get out to tons of people.
- 52:30So there are a lot of efforts now to say,
- 52:32how can we use our new technologies that we have now,
- 52:35that we're developing on a research scale,
- 52:38to make cheap, quick tests that could be distributed
- 52:42and could allow people to be diagnosed more widely.
- 52:46- [Saad] Before I open up for questions,
- 52:49I just want to remind everyone that outbreaks,
- 52:51as the plague in Europe or the 1918 flu pandemic
- 52:56or more recent Ebola outbreak, et cetera,
- 52:59can bring the best and the worst out of people.
- 53:01It's extremely important for us to treat each other
- 53:04with dignity and respect and compassion.
- 53:07Dignity and respect and tolerance is somewhat passive
- 53:12ways of looking at the world
- 53:16and in my short time at Yale, I think I can fairly say
- 53:22with some confidence, this is not a passive community.
- 53:25So it also demands that we are active in our compassion,
- 53:30for our peers, for our students, not just when the outbreak
- 53:34is in China, but when we have a scenario,
- 53:38that your mom or uncle or cousin from Colorado calls
- 53:42and says, "I've heard this thing on Twitter"
- 53:47and there is that tone of concern and fear,
- 53:51that is part of that conversation.
- 53:55So as part of the Yale community,
- 53:57it our responsibility to in these kinds of situations,
- 54:02I'm not saying this is gonna happen,
- 54:04with this and uncertainty doesn't mean
- 54:06that it's gonna explode,
- 54:08it means that it could go on the other side as well.
- 54:14But if it does happen, my hope is that all of us,
- 54:18would look back on this year,
- 54:20as part of the Yale community, most of us who are here,
- 54:24and we'll be proud of our response as a group of people.
- 54:27So let's just remember that before I open this
- 54:30and have no doubt that it's not gonna happen,
- 54:33absolutely gonna happen.
- 54:34But my hope is that we go one step beyond that,
- 54:37we bring the same passion and compassion
- 54:42and lack of passivity to this as we bring to the other
- 54:46parts of our endeavors at this campus.
- 54:48So the way, there is a microphone somewhere,
- 54:51yes, there're a couple of microphones on either side.
- 54:55So please ask your questions, state your name, et cetera
- 55:00and if you have an affiliation one way or another,
- 55:05if you're comfortable please state that as well.
- 55:09Please raise your hands.
- 55:13Yes, this one here.
- 55:19- [Mark] Hi, Mark Russi, Yale School of Medicine and also
- 55:22Yale health system.
- 55:24In 2003, there was a lot of discussion about the phenomenon
- 55:29of a super-spreader (mumbles) of Hong Kong,
- 55:33the index patient at the Metropole Hotel.
- 55:37Are you seeing, perhaps this is question
- 55:39for Nathan and Ellen, are you seeing anything, either
- 55:43potentially ascribable to host factors or to some
- 55:46combination of low levels of humidity, directional airflow,
- 55:51et cetera, that leads you to believe that there are cases
- 55:55where there is a substantial excursion from the R0 that
- 55:59we're seeing of about two and a half for this disease?
- 56:08- [Ellen] I will start by saying I don't really know
- 56:11the answer to your question.
- 56:13The only thing that comes to mind is this.
- 56:16There was a report in several Chinese media outlets,
- 56:21that they tested environmental samples,
- 56:24at that Wuhan market,
- 56:25and there was a good number of them
- 56:29tested positive for the virus.
- 56:32So that suggests that at least at that market,
- 56:36there was a spot where there was a lot of this virus.
- 56:40Why that was is not clear, but there was a spot
- 56:43where there was a lot of this virus.
- 56:45Was it from an individual who was shedding it?
- 56:48Was it from an animal?
- 56:50I don't know the answer to that, but that's the only thing
- 56:54that I can think of that I've read about
- 56:56or heard about that would suggest what you're talking about.
- 57:00I don't really know the answer to that with regards to any,
- 57:04I have not heard of any reports of super-spreaders
- 57:06or anything like that at this point.
- 57:07I don't know if anyone else might know.
- 57:13- [Saad] Do you want to say something?
- 57:17So there's a question at the back, right hand side.
- 57:20- [Wu] Hello, Wu from School Of (murmurs).
- 57:22Okay so I have some questions, first one is,
- 57:24is there any scientific way to learn the quality
- 57:27of the data published by Chinese officials?
- 57:30And the second question is emphatically, if the initial
- 57:32outbreak is happening in New York,
- 57:35which has the closest resemblance to high-insurance filled
- 57:38population and mobility and if the public health official
- 57:41was notified two weeks after the initial outbreak
- 57:44how can things handle different?
- 57:47- [Saad] So I will, so Nate, you have thought
- 57:50a little bit about sort of information quality
- 57:53around this Rpeg, do you have nay thoughts to contribute
- 57:57to on this?
- 58:00- [Nate] You can start it, I'll join in.
- 58:01- [Saad] I'm sorry?
- 58:02- [Nate] I said you can go ahead and start me.
- 58:02- [Saad] So I can start.
- 58:03So that's a really good question, so we don't have a direct
- 58:08sophisticated way of saying that what a given paper
- 58:14is saying is valid, other than we do have tools,
- 58:17they are tools that have been with us and have served us
- 58:20overall well, but not perfectly, for decades,
- 58:23if not centuries and that, the most effective tool,
- 58:26is called peer review.
- 58:27And that's where someone else, who's not involved
- 58:31with this whole process, says,
- 58:34"But there's something odd about this."
- 58:37And then they sort of, they question, they push back,
- 58:40and if the responses are not satisfactory,
- 58:44then sometimes the paper doesn't get published, et cetera.
- 58:48So that has changed, we are in a very different
- 58:51communications environment now.
- 58:53Scientific communications environment,
- 58:55in this kind of situation, the results of these products,
- 59:05intellectual products, are being shared on Twitter
- 59:08before they are even submitted
- 59:09they are on preprint servers, et cetera.
- 59:12Which is okay, which is overall sharing
- 59:14the viral genome quickly and publishing that
- 59:17has a lot of value.
- 59:19I think we'll have to compliment that with a rapid,
- 59:24standing peer review system.
- 59:27That looks at that and says,
- 59:30"We are gonna perform peer review.
- 59:32"You have posted it on a preprint server."
- 59:34The preprint server flags it,
- 59:35sends it out to this group that has signed contracts,
- 59:38maybe pay them to have this commitment.
- 59:41Say, I'm gonna turn around because there's a finite
- 59:44types of people that you would need
- 59:47in an emerging pathogen kind of a situation.
- 59:52You would need epidemiologist, you would need virologists,
- 59:54you would need a few clinicians who would pay attention
- 59:58to these kinds of things.
- 59:59So you can have them on a retainer in future situations
- 01:00:02where you say that this paper is submitted
- 01:00:06to this preprint server.
- 01:00:07We evaluate quickly and we say does that make sense or not
- 01:00:12before you know while the information is still out there
- 01:00:15we give it a stamp of approval or otherwise.
- 01:00:17So that would be a way to do that?
- 01:00:19Any other thoughts, Nate?
- 01:00:21- [Nate] Yeah, I'll just say something
- 01:00:22on the quality of the data that's coming out.
- 01:00:25So one thing that's really important to keep in mind here,
- 01:00:29is the sheer number of cases that are being reported a day
- 01:00:32now into like the 3 thousands.
- 01:00:35Those are at least then, 3000 tests
- 01:00:37that are being performed a day
- 01:00:39and probably not all of them are positive.
- 01:00:41So you gotta think about some of it may,
- 01:00:44the quality it may not really reflect what is happening,
- 01:00:47I don't think it has anything to do with the quality
- 01:00:49of the reporting per se.
- 01:00:51It's just like, how many tests can you actually do
- 01:00:53in some of these places everyday,
- 01:00:55to get that information out.
- 01:00:56So there's going to be under-reporting that's happening,
- 01:01:00that isn't necessarily deliberate by any means,
- 01:01:03but it's just sort of a function of overloading systems.
- 01:01:09- [Sten] I mean, the only thing we can say is
- 01:01:12that data-sharing is important at this moment.
- 01:01:13It's like, whoever has data needs to share it
- 01:01:15at a global scale among the scientific communities.
- 01:01:18'Cause it's not just what you see in the publication
- 01:01:20that's important, it's the raw data
- 01:01:22that people can run re-analysis on
- 01:01:24and there's some question about whether all the data's
- 01:01:26being shared in sort of a transparent way
- 01:01:29at the current moment.
- 01:01:31- [Saad] That's a very important point.
- 01:01:33- [Ellen] One more comment about
- 01:01:34the preprint servers though, it is quite amazing
- 01:01:37that Nate talked about that sort of wrong analysis
- 01:01:41misconcluding about the HIV present
- 01:01:44in the coronavirus genome, but I have to say
- 01:01:46that went up on a preprint server, many scientists read it,
- 01:01:50many scientists commented about it, and said,
- 01:01:53"This is a problem."
- 01:01:54And the authors took it down and apologized.
- 01:01:57And that all happened like within a few days.
- 01:01:59So actually in a way, the system is, there is sort of this
- 01:02:02informal peer review going on.
- 01:02:04Likewise, with the New England Journal article
- 01:02:08that was retracted.
- 01:02:09So there is sort of an informal process that's kind of
- 01:02:13coming out of our global connectivity,
- 01:02:15which is sort of encouraging.
- 01:02:17- [Saad] So I'm generally a glass 10% full kind of person,
- 01:02:20It's always something to be hopeful about.
- 01:02:23With this exception, after having worked in vaccines,
- 01:02:26I've interacted with a few swamps of 4chan,
- 01:02:29where these conspiracies live and thrive and multiply
- 01:02:35and my concern is, even after all the retractions,
- 01:02:39some of that stuff will find a life of its own.
- 01:02:43But it is, there is always these kinds of things
- 01:02:46have trade-offs.
- 01:02:47I think having access to especially raw data,
- 01:02:51but also some of the analysis quickly,
- 01:02:54my tendered objective is, it's a net positive.
- 01:02:58A net positive not by sort of close margin,
- 01:03:02but substantially, but it has had, to quote Batman,
- 01:03:09or actually, Spider-man,
- 01:03:10"With great power, comes great responsibility."
- 01:03:13Voltaire said it,
- 01:03:14but he probably didn't say it wearing tights.
- 01:03:16(audience laughs)
- 01:03:19But so with the power of sharing that information,
- 01:03:24it is our responsibility to guard the veracity
- 01:03:28and the quality of that information,
- 01:03:29through the full scientific process.
- 01:03:34- [Ley] I can talk without the mic, I'm Ley Chen-
- 01:03:36- [Saad] So we have broadcasting, so
- 01:03:38- [Ley] So I will wait.
- 01:03:41- [David] Who was the person in the back
- 01:03:42that was there first.
- 01:03:46- [Lay] Should I wait, Lay Chen, School of Medicine,
- 01:03:48Department of Pediatrics.
- 01:03:50I have a question about the,
- 01:03:53seemingly the difference in mortality
- 01:03:55between Wuhan patients and those outside.
- 01:03:58Do you think that's simply a question of not knowing
- 01:04:00the denominator of how many people are really sick
- 01:04:03outside of Wuhan or it's something specific
- 01:04:08about the environment?
- 01:04:12- [Saad] So, Albert, do you have any thoughts on that?
- 01:04:13- No, go ahead, I don't know.
- 01:04:14- The mic right there.
- 01:04:16- [Albert] So I think that of course the numbers
- 01:04:18coming out of Wuhan are very concerning,
- 01:04:20especially because of the number of deaths
- 01:04:22and the proportion of deaths.
- 01:04:23But this is kind of very much like many epidemics that occur
- 01:04:28at the epicenter, the cases that were identified were
- 01:04:33primarily severe cases.
- 01:04:35You can tell by the age, the average age is around 60,
- 01:04:38in cases that were reported.
- 01:04:40If you compare that to what we're seeing among travelers
- 01:04:45or evacuees that are being identified,
- 01:04:47we're seeing that all ages
- 01:04:48and many of them are having mild symptoms.
- 01:04:52So this is probably as you're suspecting, we call it
- 01:04:56case ascertainment bias, in that many of the cases
- 01:04:58in the initial part of the epidemic were more severe.
- 01:05:03- [Saad] So I'm gonna come back to the question
- 01:05:04that was asked, it was a two part question.
- 01:05:06And one of them was what would happen if something like this
- 01:05:08was reported in New York City?
- 01:05:10And I think that's an important question,
- 01:05:12and we should keep it in mind before we criticize other
- 01:05:15entities, countries, in Africa or in Asia or in wherever,
- 01:05:19in terms of what would happen.
- 01:05:20Both in terms of, it's a good counter-factual,
- 01:05:22both positive and negative as well.
- 01:05:24So any thoughts on that?
- 01:05:27- [David] Well, in New York City,
- 01:05:28you have quite a bit of history,
- 01:05:31and it's also a major, in New York City I think there's
- 01:05:36greater preparedness based on a history
- 01:05:41and certainly a recent history of events that have happened.
- 01:05:45So there's memory, if you will, and preparedness
- 01:05:48that goes along.
- 01:05:51The second part is that the information and decision-making,
- 01:05:56is much more de-centralized
- 01:05:59and so that decisions can be made much faster
- 01:06:03than what's being reported overseas.
- 01:06:08So again, how much preparedness is there?
- 01:06:12The experience with it, what's the level of decision-making,
- 01:06:15I think those would be three of the bigger buckets
- 01:06:18and we could probably flesh that out more.
- 01:06:21- [Saad] So we were fortunate to have folks from
- 01:06:22the health department or experience with health department
- 01:06:25so as the mic goes there,
- 01:06:28I want to talk to Paul a little bit.
- 01:06:30Dr. Jensen, any thoughts about hospital preparedness
- 01:06:35in this kind of a situation?
- 01:06:37- [Paul] For Yale?
- 01:06:37- [Saad] For Yale.
- 01:06:39- [Paul] Yeah. Well, first just to say
- 01:06:41that the Wuhan hospital is full,
- 01:06:44the capacity for surge is a real question.
- 01:06:50We have a fairly elaborate preparedness plan,
- 01:06:55including the capacity to setup a field hospital
- 01:06:59at the Lanman Center at the gym in a case of need,
- 01:07:03but the concern about how we would be able to respond
- 01:07:08to a large number of pupils with serious illnesses,
- 01:07:10is a real one.
- 01:07:15I just can't say, but there's a balance on one hand between
- 01:07:20trying to balance anxiety and concern,
- 01:07:22which is predominately what we're dealing with now
- 01:07:25over against the issues of what would really happen
- 01:07:27in the event of an outbreak.
- 01:07:32And then just speaking to one point that she made,
- 01:07:33a little bit tangential about self-efficacy
- 01:07:36and the need that people have
- 01:07:39to feel like they're doing something,
- 01:07:41anyone hasn't had their flu shots, please get one.
- 01:07:44(audience laughs)
- 01:07:48- [Drew] Sir, I'm Drew Hadler, I was a former Connecticut
- 01:07:51state epidemiologist.
- 01:07:53For the last 11 years I've been working in emerging
- 01:07:55infections program here, but also as a consultant
- 01:07:56to New York City Health Department.
- 01:07:59So I think I came from a control perspective, I can't say
- 01:08:02what the reaction would have been, but I think
- 01:08:05from the information-gathering perspective,
- 01:08:07it would have been much, much more focused
- 01:08:10and the information will be out there
- 01:08:12a lot of the information that we need.
- 01:08:14So for example, I was there when pandemic flu hit in 2009
- 01:08:20and New York City had a huge high school outbreak
- 01:08:22it was one you could see through the city,
- 01:08:24where four or five kids came back from vacation from Cancun,
- 01:08:28turned out they had H1N1 they went to the same high school
- 01:08:31and within two weeks, there were 900 cases
- 01:08:34in that high school and at least that many family members.
- 01:08:37That was a fair amount of resources went into that,
- 01:08:42it was fully described, transmission issues were described,
- 01:08:45speculant disease within that context was described,
- 01:08:49the city also setup surveillance
- 01:08:50for hospitalized cases of H1N1 right away,
- 01:08:53'cause they didn't have it going on quaran,
- 01:08:55and quickly had counts of am I in trouble, is this going on.
- 01:08:59They also had mortality surveillance and so within a month
- 01:09:04we had a full spectrum of really good information
- 01:09:08to say that H1N1 was no more (mumbles) can sense,
- 01:09:13then any seasonal influenza.
- 01:09:16We do know it was effecting children more than older adults,
- 01:09:20which the (mumbles) seem to believe
- 01:09:21there's good explanations for that,
- 01:09:24because older adults, people in their 50s,
- 01:09:2540s, 50s, and older, actually it turned out
- 01:09:28did have some immunity to H1N1.
- 01:09:30And weren't quite as severely as effected as younger people.
- 01:09:37So basically we could put it in perspective
- 01:09:38and then base control measures on that.
- 01:09:40Again, I don't know what the immediate control measures
- 01:09:43were dealing with this but there would have been
- 01:09:46surveillance setup that would have attempted to find,
- 01:09:49full measure of the disease, how severe it was, and CDC
- 01:09:54would be invited in as it was then.
- 01:09:57Which actually helped the CDC (mumbles) station because
- 01:09:59we can see the life department anyway
- 01:10:01and so there would be a lot of communication with CDC,
- 01:10:04daily conference calls with jurisdictions around the country
- 01:10:08to explain what would be happening if New York City
- 01:10:11is the one that was affected and we'd have the information
- 01:10:17we need to try and have a rational response to it.
- 01:10:19Not one that's sort of all desperate.
- 01:10:29- [Saad] There's someone in the back, there.
- 01:10:35- [Thatcher] Thank you, Thatcher, School of Public Health,
- 01:10:40New (mumbles) Health.
- 01:10:41So my question is about the large number of patients
- 01:10:42so since the outbreak a large number of patients,
- 01:10:49with mild or severe, no matter mild or severe,
- 01:10:51they rush to the hospitals so I believe the number
- 01:10:55is quite more than 10 times,
- 01:10:5810 times more than the hospital can feed.
- 01:11:02So my question is, so would you recommend people with mild
- 01:11:07symptoms not to go to hospital and just to stay at home?
- 01:11:13- [Saad] So I can start the response,
- 01:11:17and if anyone has anything to add
- 01:11:19or you have any thoughts on that.
- 01:11:21So this is very important.
- 01:11:22So at the big public health response level,
- 01:11:25in an emerging situation,
- 01:11:26having clear evidence-based communication,
- 01:11:29is extremely important.
- 01:11:31So talking to people that at certain stage of the outbreak
- 01:11:35and response, certain kinds of symptoms, need to stay home
- 01:11:42for the "abundance of caution" in terms of the individual
- 01:11:44response may require, if there is a judicious use,
- 01:11:47to self-isolate without disrupting the more old-fashioned
- 01:11:54society in that sense.
- 01:11:57But also, so Dr. Jensen mentioned, Paul mentioned,
- 01:12:00something very important, getting your flu shot.
- 01:12:04And the reason why you say it's not biological, is that
- 01:12:08flu shot doesn't protect against the coronavirus.
- 01:12:11But it does protect against a major respiratory illness.
- 01:12:15So it helps in two ways.
- 01:12:16First of all, it has it's own benefits in terms of
- 01:12:21reducing morbidity and mortality in several age groups.
- 01:12:25But also it reduces, if you are reducing symptoms,
- 01:12:29of respiratory illness in a population,
- 01:12:32then unnecessary visits
- 01:12:34that were not caused by Coronavirus go down.
- 01:12:38So again, we're not helpless, passive, spectators
- 01:12:43to something that is unfolding.
- 01:12:46We have inherent self-efficacy in the form of
- 01:12:51for example, hand-washing, which is evidence-based
- 01:12:57measure for all respiratory illness, flu shot,
- 01:12:59and some of the other measures.
- 01:13:00Do you want to say something more, Paul or Albert,
- 01:13:03any thoughts on this?
- 01:13:05- [Paul] Yeah, I think that's very important.
- 01:13:09Also just to, a less likely influenza is in the community,
- 01:13:16the more likely it is to be able to
- 01:13:17assess people with respiratory infection quickly
- 01:13:20and efficiently in the event
- 01:13:22that we do have an outbreak of coronavirus.
- 01:13:28- [Sten] That's an interesting point, I did it in a study
- 01:13:30awhile back, looking at if you have syndromic surveillance
- 01:13:34in New York City, looking for outbreaks,
- 01:13:36can you immunize people enough
- 01:13:38so that you have greater specificity.
- 01:13:42And the challenge of getting enough people immunized
- 01:13:46is there, so from a population perspective as a concept,
- 01:13:49I think it's great, but that could also add to the case
- 01:13:55that we want to make, is that's another reason
- 01:13:58why we should be encouraging immunization.
- 01:14:02- [Saad] Yes, there's a question there.
- 01:14:03- [Hadjur] Hadjur from the (mumbles) So as a Chinese,
- 01:14:08all my family is still in China
- 01:14:10and my friends share me all these information all day.
- 01:14:14So my question or wondering is when will this end?
- 01:14:19I think the correct question is when do you expect
- 01:14:23the turning point will be?
- 01:14:25Some experts say we have incubation period of two weeks,
- 01:14:31and since the quarantine of the whole, has seen
- 01:14:35a lot of quarantined have been taken,
- 01:14:38there is roughly 10 days or two weeks already passed,
- 01:14:44So if you're doing some modeling or forecasting when do you
- 01:14:48expect this (mumbles) will show?
- 01:14:54- [Nate] I'll just start with something basic on this.
- 01:14:56So just based on one model that I've seen,
- 01:14:58and I don't know necessarily if this is going to be
- 01:15:00the most accurate prediction, but it was looking like
- 01:15:03mid to late February would be the peak.
- 01:15:06But there's a lot of things that can happen,
- 01:15:08between now and then, that would even change those estimates
- 01:15:11and then you have to wonder, the data
- 01:15:13that this is all based on.
- 01:15:14So I don't know if we have a really great handle
- 01:15:18on when this is going to be peaking
- 01:15:21and when it's going to start coming down.
- 01:15:24- [Saad] An enough providing false assurances,
- 01:15:26I think it's reasonable to share experience
- 01:15:28with other corona viruses, especially SARS,
- 01:15:32but there does seem to be a seasonality associated
- 01:15:34with those viruses.
- 01:15:36And they seem to be more transmissible using the term
- 01:15:41loosely in this kind of a situation,
- 01:15:44the peaks are higher in winter.
- 01:15:48So there is, again, tentative hope that some of those months
- 01:15:55will have a positive impact.
- 01:15:57But again, it's tentative, we are dealing with,
- 01:16:01I would be providing false assurances by providing
- 01:16:04some certainty around that.
- 01:16:06- [Sten] I think the fairest thing
- 01:16:07is that we don't know, during the Ebola outbreak
- 01:16:10there were multiple mathematical models that predicted
- 01:16:12wide sort of trajectories of the epidemic.
- 01:16:14So I think that information is trickling out,
- 01:16:18to parametrize these models, so until we have more data,
- 01:16:22until we have more sort of examination
- 01:16:24of how these parameters were put together,
- 01:16:26I think the safest thing is to say, we don't know.
- 01:16:34- [David] I taught with Alex Langmuir, who was the founder
- 01:16:37of the immunologic intelligence service.
- 01:16:41And the one thing that we used in class was Farr, right?
- 01:16:46Farr's law, and it's the first law of epidemics which is,
- 01:16:51"Whatever goes up, must come down."
- 01:16:54So we don't know where that point is-
- 01:16:59- [Saad] Sorry, did you say that you sort of
- 01:17:01talked to Langmuir himself?
- 01:17:03- [David] We taught together.
- 01:17:05- [Saad] Oh, you taught together, okay.
- 01:17:06So you were professor at the age of 12, I guess.
- 01:17:08(audience laughs)
- 01:17:10(mumbling)
- 01:17:12- [Jerry] Hi I'm Jerry Friedlander, School of Medicine,
- 01:17:17School of Public Health.
- 01:17:20So one of the real unusual characteristics of this
- 01:17:23is how rapidly it's spread globally
- 01:17:27and in a month's period of time this is (mumbles)
- 01:17:30so many countries. It's very different (mumbles) precipice.
- 01:17:35Unfortunate time in which this occurred
- 01:17:38and people traveling.
- 01:17:41So I wonder what we know about the response in other places?
- 01:17:45We're most concerned about what happens here
- 01:17:48in the US, but this is a global epidemic now,
- 01:17:51of some magnitude that we don't really know.
- 01:17:53The response will be different in different places
- 01:17:57and that's gonna have consequences actually
- 01:17:58for the global nature of this and (mumbles)
- 01:18:03and the future.
- 01:18:04So is there any coordination, on an international level
- 01:18:08at this point?
- 01:18:10Can we, somehow or other, advocate for this
- 01:18:14if it's not going on in a way that's actually functional
- 01:18:18and important and the information coming from other
- 01:18:22places will be very, very important in terms of what
- 01:18:25we understand and how we can respond.
- 01:18:27- Albert might-
- 01:18:28- [Saad] Albert, you wanna?
- 01:18:29(mumbling)
- 01:18:30- [Albert] I think this is being videotaped.
- 01:18:33(audience laughs)
- 01:18:36So the politically correct answer is that, of course,
- 01:18:39there is coordination,
- 01:18:40and that coordination is being done by WHO,
- 01:18:44on many different levels in terms of operating response,
- 01:18:46in terms of training, capacity and so forth.
- 01:18:50But we all know the situation with WHO
- 01:18:53has been essentially neutered
- 01:18:54because of the lack of multi-level funding.
- 01:18:58Much of the funding is bilateral and which is really
- 01:19:02incapacitated some effective responses and coordination.
- 01:19:07So I'm being a little harsh on that, but I think that is
- 01:19:11a gap and that's why we have this myriad of bi-lateral
- 01:19:15responses which are potentially not well-coordinated.
- 01:19:19And I think the concern and I'm just gonna jump on to,
- 01:19:22I think what Kai said, and others, is that
- 01:19:25I mean, this is I think we're still in the exponential phase
- 01:19:30of the epidemic in many of the cities
- 01:19:33of the 5 million people who left Wuhan before.
- 01:19:37We don't know the exact proportion of who's effected but
- 01:19:39I think it's fair to say, with regard to provinces,
- 01:19:42Shanghai and Guangdong are in the exponential phase.
- 01:19:46And that delay of models,
- 01:19:48which has been modeled three days,
- 01:19:49and maybe much longer,
- 01:19:51so I think we're in for the long-term.
- 01:19:53I think the big question is, is that
- 01:19:54in places that have weaker surveillance systems,
- 01:19:57I'm thinking about Southeast Asia, South Asia, maybe
- 01:20:00there's only three cases, but how many kits are available?
- 01:20:04And so the concern is we can go all the way
- 01:20:08back to the beginning of what Nate said,
- 01:20:11this is probably one of seven pandemics or so,
- 01:20:14of the coronavirus, it would be good to be optimistic
- 01:20:18it would be good to think that we can push this
- 01:20:21into a season that has low-transmission.
- 01:20:23But I think we have to tie it on this being, spreading
- 01:20:30and not necessarily peaking early.
- 01:20:33And I think we also have to plan on what's gonna happen
- 01:20:36in the most vulnerable populations around the world.
- 01:20:39And what happens when it gets there,
- 01:20:41and this is a case fatality rate, that may not be as high
- 01:20:44as MERS or SARS,
- 01:20:46but it's not going to be negligible either.
- 01:20:49- [Participant] It's going to be heterogenous
- 01:20:51in different parts of the world, seasonally.
- 01:20:55- [Lisa] So, I want to go back to a question that was asked
- 01:20:56earlier about the people going to, with mild infection,
- 01:21:00going to the hospital.
- 01:21:02And I think that a lot of that could be prevented
- 01:21:05if we had a very good sense of what the natural history
- 01:21:08of this disease was and what it looked like
- 01:21:10when it was bad.
- 01:21:12Like, does it start off mild and become bad?
- 01:21:16That's one disease pattern.
- 01:21:18Or does it start off bad and stay bad?
- 01:21:20If it starts off bad and stays bad,
- 01:21:23then if you got a mild case, then you shouldn't go
- 01:21:25to the hospital.
- 01:21:26But until we know what that is, until we can describe it
- 01:21:30and make that public, people, of course,
- 01:21:33are going to go to the hospital
- 01:21:35with even the mildest symptoms 'cause of course
- 01:21:37they're worried.
- 01:21:39And rightfully so perhaps,
- 01:21:41but I think that's one of the pieces of information,
- 01:21:44that we really need to get out to people.
- 01:21:46Is what does it look like when it happens.
- 01:21:50Like, is it bad all the time?
- 01:21:52Or does it start off mild and get bad?
- 01:21:55That's an important distinction.
- 01:21:57- [Saad] So, in the interest of time,
- 01:21:58I want to finish on time, I'll take only a couple of more
- 01:22:00questions and there were a few questions on this side.
- 01:22:05We spent some time on this side for awhile,
- 01:22:08so you had a question for awhile
- 01:22:11and then there was one more in there.
- 01:22:12So unfortunately we will have to stop here
- 01:22:15and I'll be happy to stay back and maybe others
- 01:22:19will also stick around.
- 01:22:21- Hi I'm (murmurs) from the department of internal medicine
- 01:22:24and herbology.
- 01:22:25I was wondering, you mentioned seven of these corona viruses
- 01:22:28some causing cold and yet some like SARS
- 01:22:31with a lot of fatality do we know, biologically,
- 01:22:34what is different about the SARS
- 01:22:38versus the ones that cause colds
- 01:22:41and causes this without fatality
- 01:22:46and can use that information
- 01:22:46when we're studying mutations in this current coronavirus
- 01:22:49to predict potentially what might be more of a problem?
- 01:22:56- [Saad] Start?
- 01:22:57- [Ellen] I can start, I can start on that one.
- 01:23:01Well, one interesting thing is there's a coronavirus,
- 01:23:06the corona viruses that circulate every year in New Haven
- 01:23:09and throughout the US, sometimes cause colds
- 01:23:11and they can cause serious illness,
- 01:23:13particularly in people who have other health conditions
- 01:23:16kind of like what we've seen a little bit
- 01:23:18with this virus too.
- 01:23:20As far as the receptor the virus uses to enter cells,
- 01:23:23this virus uses the same receptor as SARS
- 01:23:26and the same receptor as a different Coronavirus
- 01:23:29that causes colds, so that's not the key thing.
- 01:23:32With SARS there was some information about it suppressing
- 01:23:37the anti-viral response pretty well,
- 01:23:40which you can imagine would allow the virus
- 01:23:42to get to a higher level in the body.
- 01:23:46But as far as this virus, I really don't know.
- 01:23:49So it's interesting that people have studied already
- 01:23:53where those receptors are found, the receptor the virus
- 01:23:57uses to get into cells, they're in the upper airway,
- 01:24:01they're in the lower airway where the gas exchange occurs
- 01:24:03in the lung and also in other tissues of the body,
- 01:24:06like in the liver and the blood vessels
- 01:24:08and things like that.
- 01:24:10But I think there still needs to be more work
- 01:24:12on the pathogenesis of this one to figure out exactly.
- 01:24:18It's not totally clear, kind of getting back to something
- 01:24:21that was said earlier is
- 01:24:24at the beginning when a lot of people
- 01:24:27who are presenting to a hospital are very, very sick,
- 01:24:31a lot of those initial people were also people
- 01:24:34with other medical conditions,
- 01:24:35who you might expect to get ill.
- 01:24:38More ill than somebody who's perfectly healthy and young.
- 01:24:42So it's still not totally clear,
- 01:24:45how that factors into the pathogenesis we're seeing
- 01:24:47and the mortality rates too.
- 01:24:52- [Nate] Really quick, so we can go to the next question.
- 01:24:54So it does seem to be,
- 01:24:56if the virus can use the ACE2 receptor,
- 01:24:58it can infect humans, if it cannot use it,
- 01:24:59then it can't infect humans.
- 01:25:02That's one of the parts of it,
- 01:25:03but whether this is gonna be SARS or a common cold?
- 01:25:07We can't just look at the genome and sort of gaze at it yet.
- 01:25:10We don't have the tools or enough data to say
- 01:25:12how bad this is gonna be, that's not quite possible.
- 01:25:17- [Saad] So there was another question from there
- 01:25:19or that has been answered by?
- 01:25:21So I'll come to Evelyn and then I think we have,
- 01:25:24I said two or one more, sort of
- 01:25:27time for one more question, et cetera.
- 01:25:30So Evelyn, do you want to?
- 01:25:31- [Assistant] Michael can we do this question and then I-
- 01:25:35- [Saad] Okay.
- 01:25:36- [Evelyn] So I know China just finished building
- 01:25:39a thousand person hospital isolation ward.
- 01:25:43What do y'all think?
- 01:25:44Is this an efficient way to contain the outbreak
- 01:25:47or are we gonna end up
- 01:25:48with more issues than we started with?
- 01:25:51- [David] I'm curious about the construction and the quality
- 01:25:57and the resources that go into that,
- 01:26:00supplies that are available, what's the access?
- 01:26:04Really don't have enough information about the specifics.
- 01:26:08But I am gonna turn it over to Gregg, who does.
- 01:26:12(audience laughs)
- 01:26:13- [Gregg] No, but that's not the point, the point is that
- 01:26:15we can't abandon our Chinese brothers and sisters
- 01:26:19and say like, "Let 'em do what..."
- 01:26:22The point is that the conditions of confinement
- 01:26:24have to be clinically suitable
- 01:26:27and meet human rights norms.
- 01:26:28And if they're being dumped in a hospital
- 01:26:30with poor infection control
- 01:26:31and without sufficient clinical capacity
- 01:26:34to take care of people, it's not the right thing to do.
- 01:26:36We all have friends in China
- 01:26:39and we need information to get out
- 01:26:41so that people are taken care of both in their communities
- 01:26:44and in any facilities they might be sent to.
- 01:26:48- [Evelyn] Hi, Evelyn Shay from the School of Medicine
- 01:26:50and Public Health.
- 01:26:52I actually wanted to follow up on Jerry's question
- 01:26:55and hear from Albert, when you said there are myriad
- 01:26:58bi-lateral initiatives, is that countries with China?
- 01:27:03I'm curious to know sort of the degree to which
- 01:27:06there's a partnership with China,
- 01:27:09whether it's CDC or government
- 01:27:11and how effective that has been?
- 01:27:15How much are they doing this on their own domestically?
- 01:27:20How much is their engagement, it's a little bit hard to tell
- 01:27:24from the outside.
- 01:27:26(presenter chuckles)
- 01:27:27And I think this goes along with what Gregg was saying,
- 01:27:31to what degree is there-
- 01:27:39- [Albert] So I'd very much like Sten or David to answer
- 01:27:43this question.
- 01:27:45(presenter laughs) (audience laughs)
- 01:27:51- [Sten] My authority is my friends in China on WeChat.
- 01:27:55Who've been lighting up my phone all week.
- 01:27:59And it does seem like the Chinese
- 01:28:01are pretty much on their own on this one.
- 01:28:03There isn't any substantial international help
- 01:28:06infrastructure in Hubei province in Wuhan city.
- 01:28:11The US CDC has a presence in Beijing but I'm going to guess
- 01:28:18that there isn't a coronavirus control expert in the group.
- 01:28:21But they do have good, solid (murmurs),
- 01:28:23just that it's not improbable that there's communication
- 01:28:27with the China CDC.
- 01:28:29China's CDC's a pretty sophisticated operation.
- 01:28:31They have a sort of a command center
- 01:28:36for outbreak investigations some I visited that reminded me
- 01:28:40of the CDC command center and was modeled after it.
- 01:28:43And I am thinking that the Chinese
- 01:28:47are largely tackling this on their own.
- 01:28:49I have no evidence to the contrary
- 01:28:51and my friends at WHO are not deeply engaged.
- 01:28:54I know people high up in the state department
- 01:28:58that I talk to and they're helping the Chinese,
- 01:29:00but they're helping them from Geneva and from Atlanta.
- 01:29:04So I think there's a lot of communication,
- 01:29:07a lot of consultation, but on the ground,
- 01:29:10the Chinese are handling this on their own.
- 01:29:12I think that's fair to say.
- 01:29:14- [Evelyn] Can I just...
- 01:29:15- [Sten] Yeah.
- 01:29:16- [Evelyn] Sorry just to follow-up,
- 01:29:22if this is helpful at all, but I was speaking,
- 01:29:23I was in Beijing recently
- 01:29:24and I was speaking to a documentary filmmaker
- 01:29:29about a film she made about emerging epidemics
- 01:29:32and she was focusing on the Ebola virus
- 01:29:35but when she was in Africa she said that the best
- 01:29:40makeshift hospital that she had encountered were the ones
- 01:29:46built from China so I think that if that's reassuring
- 01:29:51that's great infrastructure-wise
- 01:29:52but I understand-
- 01:29:55- [Sten] Just put things in perspective
- 01:29:57and I think there's a lot of issues coming around
- 01:30:01freedom of information and dissemination of information.
- 01:30:05As I said,
- 01:30:06the Chinese CDC is a very sophisticated organization
- 01:30:10and once, and I think this is up to debate
- 01:30:13and this is all speculation,
- 01:30:15but once the outbreak was shown,
- 01:30:18I mean it was identified.
- 01:30:20And there are probably policy reasons why it wasn't
- 01:30:27the early warning system didn't work
- 01:30:30as it had worked with H7N9.
- 01:30:33And they detected other emerging pathogens,
- 01:30:36in the interim time between SARS and are very efficient,
- 01:30:39why it didn't work now is unclear.
- 01:30:41And that's something that
- 01:30:42I think we really don't have a good answer,
- 01:30:45but once they had detected it, and once it went into
- 01:30:47the early warning, through IHR.
- 01:30:49They followed all IHR regulations very sophisticated
- 01:30:53responses, they sequenced the genome,
- 01:30:54they are now doing,
- 01:30:57many randomized controlled trials for treatments,
- 01:31:02many of those are probably gonna come out with information
- 01:31:04in the next one or two weeks about how to cure.
- 01:31:06So very sophisticated responses on many fronts.
- 01:31:12I think we have to just put this
- 01:31:14all kind of into perspective.
- 01:31:17- [Saad] Yeah, so I'll then wrap up, I wanna wrap up
- 01:31:20exactly at seven.
- 01:31:21I know there are other questions
- 01:31:22and that's an indication of the importance of the issue
- 01:31:25and the engagement so I'd be happy to stay back.
- 01:31:27I can't speak for other people, but I'd stay back
- 01:31:32if you have other questions, et cetera.
- 01:31:35But I don't want to wrap up as we wrap for seven on time,
- 01:31:39colleagues who put it together and helped to organize
- 01:31:42on a quick notice.
- 01:31:43I'm not going to be able to go through the full list,
- 01:31:46but specifically Ros and Alyssa and Mike Skonieczny and Jen
- 01:31:52and many others from different parts, and Colin and others
- 01:31:59from YSPH and YGH et cetera.
- 01:32:02Who made this possible at a very short notice.
- 01:32:04But I will wrap up, as I wrap up, I want you to remember
- 01:32:08the intensity of response, mounted by health workers,
- 01:32:13both clinical workers, but also public health workers
- 01:32:17in China as we speak.
- 01:32:20They keep all of us safe,
- 01:32:22they have risen up to the challenge.
- 01:32:26Set aside all the politics, individual health workers
- 01:32:30and the health system, folks on the ground,
- 01:32:33have responded, not just on behalf of their own community
- 01:32:37but on behalf of us.
- 01:32:40And if there was any doubt of the sacrifice,
- 01:32:43we should remember one of the physicians
- 01:32:45who was initial canary in the coal mine, passed away.
- 01:32:49There are reports that he passed away.
- 01:32:50There were mixed reports, but I think it's now confirmed,
- 01:32:53that he passed away today.
- 01:32:55On that somber note, we should also remember
- 01:32:58that we are not helpless observers, we have self-efficacy,
- 01:33:03both as humans and as compassionate beings
- 01:33:08and as scientists, public health professionals-
