USAID Funding Cuts Could Trigger 14 Million Deaths and Devastating TB Crisis by 2030
核心洞察
USAID programs prevented 91 million deaths between 2001 and 2021, with an 83% funding cut now threatening to reverse decades of global health progress.
Tuberculosis (搜索) programs face catastrophic disruption, with projections showing up to 4.4 million additional TB cases and 884,000 deaths in high-dependency countries.
The funding freeze affects 26 high-burden tuberculosis (搜索) countries, with eight nations classified as highly dependent on US government support for their national TB programs.
The shutdown of USAID and subsequent 83% reduction in US foreign aid funding threatens to trigger a global health catastrophe, with researchers projecting more than 14 million preventable deaths by 2030. The cuts, announced following Secretary of State Marco Rubio's statement abandoning what he called a "charity-based model" of international aid, could reverse two decades of progress in global health outcomes.
Devastating Impact on Global Health Programs
USAID-supported programs prevented 91 million deaths between 2001 and 2021 in low- and middle-income countries, according to research published in The Lancet. The programs achieved remarkable success, reducing global deaths by 15% overall and cutting deaths among children under age 5 by 32%.
The health gains were particularly striking in specific disease areas. USAID support led to a 74% reduction in HIV/AIDS (搜索) deaths, 53% reduction in malaria (搜索) deaths, and 51% reduction in neglected tropical disease deaths among countries receiving high levels of support. Similar reductions occurred in deaths from tuberculosis (搜索), starvation, diarrhea, respiratory infections, and pregnancy-related complications.
"For many low- and middle-income countries, the resulting shock would be comparable in scale to a global pandemic or a major armed conflict," said Davide Rasella, research professor at the Barcelona Institute for Global Health in Spain and senior investigator of the study.
Tuberculosis Programs Face Critical Disruption
The funding cuts pose an existential threat to tuberculosis (搜索) control programs worldwide. A separate study in PLOS Global Public Health analyzed 26 high-burden TB countries that collectively account for nearly 80% of the global TB burden. These nations were categorized based on their dependency on US government funding for their National Tuberculosis Programs (NTP).
Eight countries fall into the high-dependency category, where more than 37% of NTP expenditures are funded by the US government, making them extremely vulnerable to program disruptions. Ten countries have moderate dependency (23-37% US funding), while eight have low dependency (0-22% US funding).
The US government has historically provided $200 to $250 million annually in bilateral TB funding, with programs saving more than 79 million lives and preventing nearly 3.65 million deaths in 2024 alone.
Projected Health Consequences
Under the worst-case scenario, where funding gaps are not met and TB services fail to recover, researchers project devastating consequences through 2030. The analysis estimates approximately 10.6 million additional TB cases and 2.2 million additional deaths across the 26 high-burden countries.
Even in adjusted sensitivity analyses assuming only 50% impact from US funding disruption, the worst-case scenario still projects 4.4 million additional TB cases and 884,000 additional deaths.
"Given the key role of the US as a key funder for TB research, withdrawal of USG support threatens the development of such critical new tools, further delaying progress and—without adequate mitigation—making End TB targets unattainable," the study authors explained.
Vulnerable Populations at Greatest Risk
The funding cuts will disproportionately affect the world's most vulnerable populations. Children under age 5 face particular risk, with projections showing more than 4.5 million additional child deaths by 2030—equivalent to approximately 700,000 needless child deaths per year.
"Hard-to-reach, high-risk, and vulnerable populations, previously connected to national TB programs through civil society organizations (CSOs), now face complete isolation as US-funded initiatives shut down," researchers warned.
Infrastructure Decades in the Making at Risk
Beyond immediate health impacts, the cuts threaten to dismantle healthcare infrastructure that took decades to build. Francisco Saúte, general director of the Manhiça Health Research Center (搜索) in Mozambique, emphasized this concern: "From our experience on the ground, we have witnessed how USAID support has strengthened local health systems' ability to respond to diseases like HIV, malaria (搜索) and tuberculosis (搜索). Cutting this funding now not only puts lives at risk—it also undermines critical infrastructure that has taken decades to build."
Broader International Implications
The US contribution represents a significant portion of global humanitarian funding, with the country previously contributing more than 40% of such support. Researchers express concern that other international donors might reduce their commitments in response to US cuts.
"The findings of this study are even more concerning given that other international donors—primarily in the EU—have also announced substantial reductions in their aid budgets, potentially leading to even more additional deaths in the coming years," said Caterina Monti, a predoctoral researcher at the Barcelona Institute for Global Health.
The research reveals that US citizens contribute approximately 17 cents per day to USAID, around $64 per year. "I think most people would support continued USAID funding if they knew just how effective such a small contribution can be to saving millions of lives," said James Macinko, professor of health policy and management at UCLA.
Legal and Political Developments
Federal lawsuits filed by non-government organizations and global health advocates have been under review by the US Supreme Court throughout 2025. Recently, the Trump administration's appeal to freeze $4 billion approved by the US Court of Appeals was granted by the Supreme Court, affecting funds that must be spent by the end of the month.
The funding freeze began on January 20, 2025, just two days after President Trump was sworn into office and signed an executive order claiming foreign aid no longer "aligned with American interests."
