Project Title: Understanding HIV Pre-exposure Prophylaxis Engagement among Women in East Africa

Project Summary:

Dr. Koss conducts clinical research on HIV prevention and treatment, with a major focus on developing strategies to optimize uptake of and adherence to pre-exposure prophylaxis (PrEP) among women in the United States and East Africa. She also has an interest in adherence to treatment and virologic outcomes among pregnant and postpartum women living with HIV. She is an attending physician on the HIV and Infectious Diseases consult service at San Francisco General and a clinical provider at the “Ward 86” Positive Health Practice. Globally, women account for more than half of people living with HIV, with younger women in sub-Saharan Africa at particularly high risk of HIV acquisition. Oral PrEP, an antiretroviral pill taken daily to prevent HIV, is just beginning to be introduced in much of sub-Saharan Africa and could have a major impact in curbing new infections. With support from the Hellman Fellows Fund, Dr. Koss will seek to understand engagement in the PrEP care continuum among women in East Africa to inform the development of strategies to maximize the effective implementation of this important prevention modality.
