Introduction: Men who have sex with men and transgender individuals (MSM/TG) carry a disproportionately high burden of HIV, including in South Africa. However, there are few empirical population-representative estimates of viral suppression and the HIV care cascade including HIV testing among this population, nor of factors associated with these outcomes.
Methods: We conducted a respondent driven sampling (RDS) survey among 301 MSM/TG in Johannesburg in 2017.
