With a nationwide Prevention of Mother-to-Child Transmission program, Botswana has reduced HIV transmission from infected mothers to their children from about 40% to just 4%. Under the leadership of Festus Mogae, the Government of Botswana solicited outside help in fighting HIV/AIDS and received early support from the Bill and Melinda Gates Foundation, the Merck Foundation, and together formed the African Comprehensive HIV/AIDS Partnership (ACHAP). Other early partners include the Botswana-Harvard AIDS Institute, of the Harvard School of Public Health and the Botswana-UPenn Partnership of the University of Pennsylvania. According to the 2011 UNAIDS Report, universal access to treatment – defined as 80% coverage or greater – has been achieved in Botswana.
