The world-wide incidence of Kaposi's sarcoma in the HIV/AIDS era.

Globally, a relatively high incidence of KS was found among HIV-seropositive people and, in particular, in HIV-infected MSM. The introduction of HAART has largely prevented the development of KS, but it has not entirely removed the challenge of KS. In Africa, in particular, KS imposes a very heavy disease burden, which can mainly be attributed to the high prevalence of KS-associated herpesvirus and poor access to HAART.
