As the world marks World AIDS Day, the global fight against HIV stands at a critical juncture. Despite rapid scientific progress, funding shortfalls and weakened health systems threaten to undermine efforts to combat the disease. The latest UNAIDS report warns that the international response is weakening, with falling funding and disrupted health services hindering progress.
Globally, an estimated 41 million people are living with HIV, and 1.3 million new infections were reported last year. Still, 9.2 million people lack access to life‑saving antiretroviral treatment. UNAIDS Executive Director Winnie Byanyima has described the situation as the biggest setback in decades, emphasizing that “HIV is not over” and calling for renewed global mobilization.
The Global Fund to Fight AIDS, Tuberculosis and Malaria recently raised €9 billion for the next three years—far short of the €15 billion needed. This shortfall jeopardizes crucial programs worldwide, especially in sub‑Saharan Africa, which bears a disproportionate share of the epidemic. The region accounts for 52 % of the 40.8 million people living with HIV worldwide, with 60 % of all people living with the virus residing there.
Scientific advances continue, however. Long‑acting antiretroviral treatments and injectable PrEP offer long‑term protection, and lenacapavir—recently recommended by the World Health Organization—provides six months of protection with a single shot. It is expected to become available at a significantly reduced cost in low‑resource countries. Yet these breakthroughs risk remaining theoretical unless health systems can keep pace.
Global development aid for health fell by 22 % in 2025, largely due to reductions or withdrawals from major U.S. programs. This has created a financing crisis for the fight against HIV/AIDS and broader global health, with drastic cuts from donor countries causing major interruptions in essential services. The consequences are already evident, as infections are rising again in several countries. The funding crisis, compounded by the lasting effects of the COVID‑19 pandemic, is eroding progress made since the early 2000s.
UNAIDS urges the global community to rethink the funding model, stressing that science alone cannot end the epidemic. Without a shift in financing, the world is likely to miss the 2030 goal of ending HIV/AIDS and may even face a resurgence of the disease.
