This project was funded by the U.S. Centers for Disease Control directly to NRHS. Dr. Fredrick Otieno was the P.I. There was additional funding from UKAID through Evidence for HIV Prevention in Southern Africa (EHPSA) to include STI and hepatitis testing as well as pre-exposure prophylaxis (PrEP). The test and treat study aimed to: 1) identify and test 700 men who have sex with men (MSM); 2) to assess the success of a comprehensive package of find, test, link and retain in care (FTLR) interventions delivered to HIV-infected MSM; 3) to retain those who test negative in a peer-led behavioural risk reduction program that includes retesting every 3 months; and 4) to offer pre exposure prophylaxis (PrEP) to a subset of the negative men who are at high risk for HIV acquisition. The purpose of the study is to generate the requisite evidence to inform the feasibility, acceptability, and expected outputs necessary to guide PEPFAR programming for expansion of counselling, testing, and comprehensive care and treatment as effective HIV prevention interventions adapted for MSM in sub-Saharan Africa. The study population were men who report oral or anal sex with a man in the past 6 months, are 18 years and above, and are residents of Kisumu.
