South Africa has more HIV/AIDS patients than any other country and is home to the world’s largest antiretroviral program. According to the World Bank, as of 2018 the prevalence of HIV among South Africans ages 15 to 49 was 20.4%. Nearly one in three pregnant women attending antenatal care in South Africa is living with HIV.
As South Africans with HIV move around the country, there is a risk they will disengage from the health care system or otherwise become lost to follow-up care.
