HIV and AIDS fact sheet

Progress, challenges and what we want to achieve.


Adult HIV prevalence on the mainland reduced significantly although this reduction has occurred mainly among men. The epidemic among adolescents (15–19 years) has remained stable since 2008, with no decline in adolescent HIV prevalence. Tanzania carries 5 per cent of the global burden of HIV among adolescents. The HIV epidemic shows strong regional variation, with children, adolescents, women and key populations continuing to be disproportionately affected. Mainland Tanzania has a generalized epidemic, while in Zanzibar, HIV prevalence is concentrated among key populations.
