This study explored HIV risk behavior among men who have sex with men (MSM) in Kigali, Rwanda. It found high rates of unprotected sex, multiple partners, and transactional sex. Over 70% of participants reported casual male partners and rates of condom use were low. Many MSM engaged in commercial sex or exchanged sex for goods. Based on these risks, the study recommends improved HIV services for MSM, including dedicated clinics, increased availability of condoms and lubricants, and awareness campaigns to address stigma.
