Malawi: One small miracle brings hope to thousands threatened by Aids

Grace is a happy woman. She is about as poor as you can be, earning just £6 a month selling shoes from a tiny market stall. But in the past year she has been spared the prospect of a premature and painful death. Grace Matnanga is HIV positive, as are one in three of those around her in the streets of Malawi's capital city. But unlike them, and thanks to an act of human kindness, she is on antiretroviral drugs.
