Winnie Byanyima, the Executive Director of UNAids, has issued dire warnings regarding the recent US funding cuts to HIV programs, highlighting the potential for an increase in new infections and deaths. She stresses the urgent need for the US to revert these cuts to prevent losing decades of progress in global HIV treatment and prevention efforts.

US Funding Cuts to HIV Programs Could Lead to Catastrophic Outcomes, Warns UNAids Chief
The UNAids chief warns that US cuts to HIV funding may result in increased infections and deaths over the next four years, reversing progress made in the fight against the virus.
US funding cuts to HIV treatment and prevention programs are poised to have detrimental global effects, according to UNAids Executive Director Winnie Byanyima. She cautioned that these reductions could lead to 2,000 new daily HIV infections and over six million additional deaths in the next four years. This marks a consequential shift in the battle against HIV, a struggle which has seen annual deaths decline dramatically from over two million in 2004 to approximately 600,000 in 2023.
Byanyima criticized the US government's pause on foreign aid programs, implemented by former President Donald Trump, warning of severe ramifications for vulnerable populations, especially women and girls. The initial temporary funding halt has snowballed into a far-reaching impact as many programs operated by the US Agency for International Development (USAID) face termination, including critical care, mother and baby clinics in Africa, and significant shortages of life-saving antiretroviral (ARV) medications.
While the US has traditionally been the largest supporter of HIV treatment worldwide, Byanyima expressed concern over backsliding to the 1990s when access to HIV medications in lower-income nations was severely limited. Her statements underline the urgency for the US to reconsider its funding strategy; she acknowledged Washington's historical generosity but insisted that the abrupt withdrawal of lifesaving support is detrimental.
Byanyima has not seen indications of a willingness from the US government to alter its approach, despite appeals. Compounding the crisis, traditional aid donors in Europe are also anticipated to reduce their contributions, leaving a significant gap in global HIV funding that may not be addressed by other nations.
In a poignant example, Byanyima shared the story of Juliana, a young Kenyan woman affected by the funding cessation who is now unable to access treatment crucial for both her and her newborn. The World Health Organization (WHO) has also raised alarms about the potential for eight countries—namely Nigeria, Kenya, Lesotho, South Sudan, Burkina Faso, Mali, Haiti, and Ukraine—to deplete their HIV drug supplies following the US funding pause.
As leaders like WHO chief Tedros Adhanom Ghebreyesus underline the risk of reversing two decades of progress, advocacy groups in South Africa, such as the Treatment Action Campaign, echo the concerns, fearing a regression to times when patients could not secure essential HIV services.
In light of these developments, Byanyima has proposed a potential solution to the Trump administration, suggesting a collaboration that could allow the marketing of a new US-developed ARV, lenacapavir, to millions globally, which could also yield profits and job creation within the US.
As UNAids and other UN agencies face funding crises—prompting layoffs and service reductions—stakeholders remain hopeful for reprioritization in a move towards protecting many lives threatened by HIV.
