The digital intervention will consist of weekly WhatsApp messages for six months, including reminders and information intended to support adherence to PrEP or ART.\n\nThe main question of the study is whether weekly WhatsApp messages can improve adherence to PrEP or ART among sexual and gender minorities in Brazil.
