Fewer than one in five people at risk of HIV infection today have access to prevention programs, and annual global spending on prevention falls $3.8 billion short of what will be needed by 2005, according to a new report released today by the Global HIV Prevention Working Group. The report, Access to HIV Prevention: Closing the Gap, is the first-ever analysis of the gap between HIV prevention needs and current efforts, and provides recommendations for expanding access to information and services that could help save lives and reverse the global epidemic.
