The prevalence of HIV (Human Immunodeficiency Virus) and STIs (Sexually Transmitted Infections) is very high in the trans population, due to multifactorial components.
The main risk factors for HIV in this population are unprotected receptive and insertive anal intercourse, multiple sexual partners, sex work, needles share for injecting drugs and hormones.
Physical violence, sexual assault and lack of social and family support are supplementary social risk factors.
Healthcare access is very limited in this socio-economic context. The population of transgender persons and their transmission chains (partners, clients, etc.) are highly exposed to HIV risk, but they are still "hidden" populations, not targeted by prevention programs.
Innovative preventive strategies can improve sexual health services access for these specific populations.
