The number of patients undergoing treatment has also decreased and the number of people not coming for consultations has increased.”Dr. Moyahabo Mapitsi, executive director of South African organization Anova, which supports the government in HIV testing and treatment in more than 500 clinics, explains.

With nearly eight million people living with HIV, South Africa is the primary focus of the global HIV epidemic.
