WASHINGTON, August 1, 2008 The 24,000 delegates to the International AIDS Conference in Mexico, which begins on Sunday August 3, are looking for ways to effectively use the US 10 billion a year in global AIDS commitments, to combat the epidemic. There have been successes - in the African country of Botswana, for example, mother to baby transmission of HIV has greatly decreased - but problems still lie ahead, and delegates will be stressing the need for further local – as well as global – level commitment to fighting HIV/AIDS.
