The prevention interventions included universal voluntary HIV counseling and testing provided at the household level, linkage of people living with HIV to care and initiation of antiretroviral therapy (ART) for all those living with HIV. The study was conducted in 21 urban and peri-urban communities in Zambia and the Western Cape of South Africa, with a total population of around 1 million.
