Nomautanda Siduna advises Pretty Mkhabela, a HIV-positive woman, how to stay as safe as possible amid the added threat of COVID-19 at a mobile clinic in Ngodwana, South Africa, Thursday, July 2, 2020. Across Africa and around the world, the COVID-19 pandemic has disrupted the supply of antiretroviral drugs to many of the more than 24 million people who take them, endangering their lives. An estimated 7.7 million people in South Africa are HIV positive, the largest number in the world, and 62% of them take the antiretroviral drugs that suppress the virus and prevent transmission.
