HIV Pre-Exposure Prophylaxis (PrEP) among men who have sex with men: peer communication, engagement and social networks.

HIV Pre-Exposure Prophylaxis (PrEP) has renewed optimism in controlling the HIV epidemic, despite its continued growth among men who have sex with men (MSM). The popularity of dating-sexual dating apps and digital media platforms in exchanging information and experiences about PrEP on peer social networks is recognized. However, studies on contexts, motivations, and scope in HIV prevention are scarce. The article aims to understand the dynamics of virtual and face-to-face peer networks among MSM for the decision to use PrEP, its disclosure, and publicity. Qualitative study using semi-structured interviews with 48 PrEP users from five Brazilian cities. Most interviewees share information and experiences about PrEP in peer social networks. However, its publication reveals tensions arising from the permanence of stigmas associated with homosexuality and HIV. The protagonism in exposing the use of PrEP expresses commitment to attracting new users. The relevance of peer social networks in sharing experiences and information about PrEP has the potential to diversify the target audience and expand and democratize PrEP coverage in the country.
