"My father died when I was young and my mother died in 2000," said Yomima, 14, one of 250 children known to be orphaned by HIV/AIDS in Juba, the capital of South Sudan. "The economic burden for grandparents of AIDS orphans is so great it can't be described," said Marcellina Denya, formerly a social worker. "Elderly people in Juba are earning nothing, so they are left in an impossible position. Even the small monies we are able to give make a vital difference."
