Decades of gains in reducing infections, expanding treatment access, and strengthening community-led prevention are now under strain as donor countries scale back funding and local health systems struggle to absorb the gap.
“The sudden funding decline is hitting the HIV response ‘like a shock wave,’” warned Winnie Byanyima, Executive Director of UNAIDS. She added that “the world is pulling back just when we need to push forward.”
Prevention Systems Straining as Services Begin to Unravel
According to UNAIDS, many countries that previously depended heavily on international assistance are now unable to maintain HIV programmes at previous levels. Community-based organisations—long considered the backbone of prevention and outreach—are among the hardest hit.
In several countries, prevention and support services are already shrinking or shutting down entirely.
The numbers underscore the scale of disruption: 9.3 million people living with HIV are still waiting to begin treatment globally, while 1.3 million new infections were recorded in 2024 alone.
Byanyima said the funding shortfall is producing “real consequences” across low- and middle-income countries, slowing treatment expansion and weakening the community networks that help reach high-risk populations.
Sharp Drops in Prevention Tools Across Africa
The impact is already measurable in prevention programmes across Africa.
In Uganda, uptake of PrEP—pre-exposure prophylaxis, a medication that can reduce the risk of sexual transmission of HIV by up to 99%—fell by 31% between December 2024 and September 2025.
In Burundi, the decline was even steeper at 64% over the same period.
Even basic prevention commodities are becoming harder to access. Nigeria recorded a 55% drop in condom distribution between December 2024 and March 2025, a decline UNAIDS links directly to reduced funding for outreach and supply chains.
Heavy Dependence on Foreign Aid Leaves Systems Exposed
The crisis is particularly severe in countries where HIV programmes remain overwhelmingly donor-funded.
UNAIDS reports that in eight countries where it operates, 99.9% of HIV prevention services are financed externally, with only 0.1% covered by domestic resources. That imbalance has left entire systems vulnerable to sudden reductions in foreign assistance.
“The fiscal constraints of the most heavily burdened countries are huge,” Byanyima said, highlighting the limited capacity of governments to replace lost funding at short notice.
The social consequences are also emerging. In 2024, around 570 girls and young women were newly infected with HIV every day, while more than half of women-led HIV organisations have lost funding or shut down entirely.
Community Clinics and Outreach Networks Disappearing
Across multiple countries, UNAIDS says community health infrastructure is being dismantled.
In Kenya, most drop-in centres serving key populations, including LGBTQ communities, have closed. Nigeria has lost at least five similar clinics.
Uganda has seen 45% of programmes supporting key populations either partially or fully shut down. In Zimbabwe, services for sex workers—including HIV prevention, testing, and treatment—have collapsed entirely in 2025.
Byanyima described a broader political and economic context shaping these cuts, saying: “It is proxy wars for critical minerals, for energy, for influence that are being fought, instrumentalising the rights of the most marginalised people.”
Scientific Progress at Odds With Financial Retrenchment
Despite the setbacks, UNAIDS stressed that scientific innovation has never been more advanced. New long-acting HIV prevention and treatment options, including injectable therapies and improved PrEP formulations, are now available or emerging.
“Science is offering us solutions that could end this epidemic by 2030; long-acting PrEP, long-acting prevention, long-acting treatments, medicines that we would not have thought about 10 years ago. All these are there,” Byanyima said.
However, she warned that these gains risk being undermined if funding gaps persist and human rights-based outreach continues to weaken.
A Fragile Window Toward 2030
UNAIDS maintains that ending AIDS as a public health threat by 2030 is still technically achievable. But that goal increasingly depends not on medical breakthroughs, but on political will and sustained financing.
The agency’s warning is stark: without renewed investment, prevention systems will continue to erode, treatment gaps will widen, and the momentum built over decades could begin to reverse.
As Byanyima put it, the world is now at a crossroads where scientific possibility and financial reality are moving in opposite directions—one pointing toward elimination of HIV, the other toward resurgence.
