 This study examined the prevalence of HIV infection among adolescent men who have sex with men, AMSM, in Salvador, Bahia State, Brazil. The results revealed a high prevalence of HIV infection among this population, with 5.9 percent testing positive for the virus. Factors such as self-identified sex work, low educational attainment, and lack of access to health care services were associated with increased risk of HIV infection. To reduce the risk of HIV transmission among AMSM, it is important to increase access to education, employment opportunities, and health care services. Additionally, targeted interventions should be implemented to address the specific needs of this population, including those related to sexual health and well-being.
