In South Africa, where an estimated five million people are HIV-positive and 500,000 children have been orphaned because one or both of their parents have died of AIDS-related causes, "child-headed household" is an official census category, although no one knows how many such households exist. Without "radical changes," the number of AIDS orphans is expected to quadruple by 2015. Carol Dyantyi, who runs the Soweto-based Ikageng Itireleng AIDS Ministry, and a group of 15 volunteers care for more than 100 AIDS orphans who live in the sprawling township. The group, which operates on a monthly budget of less than $1,000, pays the children's electricity and telephone bills, provides them with money to attend school, gives them clothes and brings food to them when their shelves are bare, reports the Los Angelos Times.
