 The goal of the proposed research is to assess new strategies for partner management and sexually transmitted infection STI control to reduce the spread of HIV-1 among men who have sex with men MSM in Latin America. The HIV epidemic in Peru remains concentrated within the core risk group of MSM. STI infection and re-infection are central to the continuation of the HIV epidemic among MSM in Peru. Development of improved strategies for partner notification and treatment will reduce the incidence and prevalence of STIs and ultimately reduce the incidence of HIV infection in this population. The first phase of this study used qualitative methods to explore attitudes and practices related to partner notification among MSM in Lima, Peru. Findings from the qualitative research were used to develop a quantitative survey instrument to assess partner notification decision-making processes and practices among MSM in Peru recently diagnosed with HIV or syphilis infection. Data from both quantitative and qualitative phases of the study have been used to develop a partner notification for MSM in Peru. Investigators plan to implement and assess the impact of the intervention on rates of partner notification following a diagnosis of syphilis among MSM in Lima, Peru. The investigators hypothesize that participants randomized to receive one or more partner notification tools will report a higher frequency of partner notification.
