Kathleen Wirth Hurwitz
Dr. Kathleen Wirth Hurwitz is a Research Scientist in the Departments of Biostatistics at the Harvard T.H. Chan School of Public Health. She is also an Associated Researcher at the Harvard T.H. Chan School of Public Health AIDS Initiative.
Dr. Wirth Hurwitz serves as the Senior Epidemiologist overseeing all statistical and quantitative efforts for the Botswana Combination Prevention Project (BCPP), a pair-matched community randomized trial involving more than 100,000 individuals residing in 30 communities throughout Botswana. The primary objective of this CDC-funded project was to test the hypothesis that implementing an enhanced combination prevention package, including universal treatment, will impact the HIV/AIDS epidemic by significantly reducing population-level, cumulative HIV incidence.
The first set of results on HIV incidence were published in July 2019 in the New England Journal of Medicine! Preliminary results on population uptake of HIV testing and treatment were presented in March 2019 at the Conference on Retroviruses and Opportunistic Infections in Seattle, WA.
Previously, Dr. Wirth Hurwitz collaborated with the International Training and Education Center for Health in Botswana and the Botswana Ministry of Health on a large, mixed-methods study evaluating Botswana’s National Safe Male Circumcision Program. She also served as the lead epidemiologist for a multi-site randomized trial of neonatal male circumcision in southeastern Botswana at the Botswana Harvard AIDS Institute and a prospective cohort study of treatment outcomes among HIV-exposed, uninfected infants hospitalized for severe pneumonia in Gaborone.
In addition to her field work in Botswana, Dr. Wirth Hurwitz has been deeply involved in the development and application of modern epidemiologic methods for HIV research. Most recently, she used instrumental variable techniques to correct for selection bias due survey non-participation in estimating HIV prevalence in Zambia and Botswana. Dr. Wirth Hurwitz is also working with infectious disease specialists in Boston and Botswana to (1.) apply novel predictive analytic techniques to documented HIV seroconversions within BCPP to identify subpopulations at highest risk for HIV acquisition and (2.) to develop a risk assessment tool that can be used to refer high‐risk, HIV-uninfected clients for targeted HIV prevention efforts, including TDF/FTC pre-exposure prophylaxis (PrEP).
