To amend the Foreign Assistance Act of 1961 to modify treatment activities for assistance to combat HIV/AIDS.

The bill amends the Foreign Assistance Act of 1961 to expand and elevate HIV/AIDS prevention and treatment activities as part of U.S. foreign assistance. It explicitly adds HIV pre-exposure prophylaxis (PrEP) medications to eligible assistance and designates certain HIV/AIDS prevention and risk-reduction activities as core, life-saving humanitarian assistance. The measure also broadens the definition of who counts as at-risk populations by allowing inclusion based on scientific analysis designated by the World Health Organization (WHO). In short, the bill aims to prioritize HIV/AIDS prevention (including PrEP and post-exposure prophylaxis) as essential humanitarian aid and to guide targeting of at-risk groups using WHO-based criteria.
