Donor government funding to combat HIV in low- and middle-income countries fell by $2.1 billion in 2025, marking a 25% decrease from the previous year according to a report by KFF and the Joint United Nations Programme on HIV/AIDS (UNAIDS). Total disbursements dropped to $6.2 billion in 2025, down from $8.3 billion in 2024, representing the largest single-year decline since donor funding scale-up began and pushing funding to its lowest level since 2007.
U.S. Funding Cuts Drive Drop in Disbursements
The downward trend in 2025 was driven by a decline in U.S. disbursements, according to the KFF and UNAIDS report. This contraction followed the administration’s substantial cuts in global health funding, programs, and personnel. Even with these cuts, the U.S. remains the largest donor to HIV in the world.
Did you know? Total international HIV disbursements have not sat this low since 2007.
Comparing 2025 Figures to Prior Years
To understand the scale of the 2025 contraction, analysts look back at previous benchmarks outlined by KFF and UNAIDS. Total international assistance stood at $8.3 billion in 2024 before plunging to $6.2 billion the following year. This $2.1 billion deficit stands as the sharpest annual drop recorded since international donors began scaling up their response to the epidemic.
Consequences for Affected Regions
Low- and middle-income countries that rely heavily on external donor assistance now face resource constraints. With disbursements dropping to $6.2 billion, national health systems must absorb the shortfall or scale back prevention, testing, and treatment programs. Because the U.S. administration enacted cuts to global health personnel and programs, partner nations have fewer financial and technical buffers to sustain existing care networks.
