In 1999, investigators announced that a single dose of nevirapine, a new antiviral drug, could stop the spread of the AIDS virus from infected mothers to their newborn babies. It was a discovery that 'changed the face of AIDS globally' but it came at a high price. This book is the historical account of paediatric AIDS from the first reported cases in the early 1980s to the first effective treatments in the 1990s and then to the prevention of HIV infections altogether.
