A new special report from UNAIDS warns the world faces a risk of HIV resurgence after international financing to fight the disease experienced a “profound shock” in 2025. According to the report, government funding for HIV programs fell by more than $1.5 billion, dropping to $7.3 billion — an 18% decline that marks the lowest level in nearly two decades.
The report draws attention to how that reduction in international financing could undermine efforts to prevent and control new infections. Prevention activities, in particular, have historically relied heavily on external assistance in many parts of the world, the authors wrote.
Prevention programs in several regions depend heavily on donor funding. The report highlights sub-Saharan Africa as especially reliant on outside support: donor assistance accounted for 83% of prevention program financing there two years ago. That level of dependency leaves prevention work vulnerable when international contributions fall.
UNAIDS identified several additional factors that compound the risk of a resurgence. Countries most affected by the disease face high debt burdens, which can constrain domestic spending on health. The report also cited backsliding on human rights and gender equality as a troubling trend that may undermine both prevention and treatment efforts.
Despite the overall decline in government funding, the United States continued to be the dominant donor government, supplying 74% of donor government funding reported. The concentration of donor support in one country underscores the fragility of funding streams when broader international contributions fall.
The report’s data indicate that prevention programs — including those aimed at reducing new infections through behavior change, testing, and prophylaxis — are particularly at risk when donor funding declines. In regions where local resources are limited and external assistance is the primary funding source, cuts or shocks to international financing can translate quickly into scaled-back services, fewer outreach activities, and reduced access to prevention tools.
UNAIDS’ characterization of the 2025 financing change as a “profound shock” reflects concern that the decline could reverse hard-won gains in reducing HIV incidence and mortality, especially where reliance on external funding is greatest.
The report notes that the $7.3 billion figure for 2025 is the lowest level of government funding for HIV in nearly two decades. That long-term decline signals a shift in the funding landscape after years in which international donor support played a central role in global HIV responses.
UNAIDS’ analysis links the financing trends to broader economic and political currents: high sovereign debt can limit governments’ capacity to step in when donor funding shrinks, while setbacks in human rights and gender equality can reduce the effectiveness and reach of prevention and care programs.
The STAT News summary of the UNAIDS report emphasized the key financing figures and the agency’s warning of a possible resurgence. The original UNAIDS special report is cited as the source of the data and commentary; further details beyond those included in the STAT News article would be found in the full UNAIDS report. The STAT item also noted the prominent role of the United States among government donors and the particularly high dependency of prevention programs in sub-Saharan Africa.
UNAIDS’ warning positions reduced international funding as a strategic threat to global HIV control. The report pointed to structural factors — debt, human rights, and gender equality — that could worsen the impact of funding shortfalls. The STAT coverage did not provide additional information on planned responses by donor governments, affected countries, or international health organizations beyond the contents of the UNAIDS special report.
