These are Public Service Announcements (PSAs) to promote the Tsima project. Tsima is a three-year community mobilisation intervention and research trial that Sonke is implementing in eight villages of the Bushbuckridge area in the Mpumalanga province. As the implementing agent, Sonke has partnered with the University of the Witwatersrand, the University of California – San Francisco, the University of North Carolina – Chapel Hill and Right to Care to complete the research component of the project. The main goal of the project is to mobilise communities to learn and understand that HIV treatment is also a form of HIV prevention. Scientific research has shown that in partners who are sero-discordant, that is, where one is HIV-positive and the other does not have HIV, it is very unlikely that the infected partner can transmit infection to the uninfected one. This is because if the infected partner is on antiretroviral treatment and adheres to it, the medicines can suppress the HI-virus to very low or undetectable levels, thus reducing or eliminating the risk of transmission.
