Portia Gxotelwa, 14, stands outside the family shack in Cape Town's Khayelitsha township February 24, 2010. Portia is one of five grandchildren cared for by Thenjiwe Madzinga, 66, including four who were orphaned when Madzinga's own daughter died from AIDS in 2002. Some 5.5 million people live with HIV/AIDS in South Africa -- more than in any other country -- placing a heavy burden on a society still struggling with the legacy of Apartheid.
