In the Guttmacher Report on Public Policy this month, Alan Guttmacher Institute Director of Government Affairs Susan Cohen examines the success of "ABC"-based HIV/AIDS prevention programs in developing nations. ABC stands for "Abstinence," "Be Faithful" and "use Condoms," and is the HIV/AIDS prevention model supported by UNAIDS and USAID. Cohen writes that although there is "no reason to believe that USAID is currently supporting ABC as anything other than a comprehensive program," the Bush administration's "aggressive support" of abstinence-only sex education in the United States has left some ABC advocates "questioning how long U.S.-supported ABC programs will be allowed to function unfettered."
