How do we trace the origins of viral outbreaks? How do viruses change hosts? What can evolution tell us how long a recovered person will be immune before reinfection?

Jeffrey Townsend (Yale University) and Alex Dornburg (Museum and UNC Charlotte) for an informal conversation about how scientists have mobilized to face evolving threats to human health.
