Sexually Transmitted Infections

Sexually Transmitted Infections
Sexually transmitted infections are a major public health problem because of their high prevalence, associated poor health outcomes, and the disproportionate impact on vulnerable populations such as adolescents and minorities who are marginalized because of race, ethnicity, or sexual orientation.

Yale AIDS Colloquiem Series - Linda Niccolai, PhD

Presented by the Center for Interdisciplinary Research on AIDS at Yale University, the Yale AIDS Colloquium Series (YACS) is an interdisciplinary academic forum for discussion of HIV/AIDS-related research and policy.

Current Projects

HPV vaccine impact monitoring project across Connecticut (HPV-IMPACT)
The goal of this project is to monitor the population-level impact of HPV vaccine through laboratory-based surveillance for trends in diagnoses of cervical cancer precursors and changes in HPV type distribution. 

HIV risk among commercial sex workers and their partners in Russia                       
The purpose of this project is to understand the variety of different types of sex partners, both clients and non-clients, of street-based female sex workers (FSW) in St. Petersburg, Russia.  Project goals include developing and evaluating methods for recruiting both client and non-client sex partners of FSW, and piloting data collection methods, both quantitative and qualitative, for validation and hypothesis generation. This study also included formative work with male sex workers.

Influences on HIV prevalence and service access among IDUs in Russia and Estonia
The HIV epidemic in Russia and Estonia is driven by viral transmission among injection drug users.  This proposal seeks to identify the extent to which ethnicity and stigma influence HIV prevalence among injectors and their access to HIV prevention and care services in St. Petersburg, Russia and Kohtla-Järve, Estonia.

Opt-out testing for HIV in a family planning setting: Implementation and evaluation
The goal of this project is to evaluate the impact of implementing opt-out HIV testing at six Planned Parenthood of Southern New England (PPSNE) centers.    Specifically, we seek to answer the following two questions: Does implementing opt-out HIV testing increase the proportion of routine visits that include an HIV test and ultimately increase the number of people tested? What socio-demographic and clinical factors are associated with accepting or declining an opt-out HIV test?
