They Saved $5 Billion and Sentenced 9.4 Million to Die — One Year After USAID's Dismantling, Global Health's Last Line of Defense Is Crumbling

In the short term, over the next 6 to 12 months, the most pressing crisis will be the spike in mortality among patients whose HIV treatment was interrupted. Antiretroviral therapy interruption leads to rapid immune deterioration within months, triggering explosive increases in opportunistic infections. Countries most dependent on PEPFAR — South Africa, Tanzania, Uganda, Malawi — will see visibly rising HIV-related deaths from the second half of 2026 onward. As UNAIDS has warned, South Africa alone faces 601,000 additional deaths over the next decade, and that trajectory begins now.

Simultaneously, plummeting TB detection rates mean "invisible transmission" is spreading unchecked. TB requires active detection and treatment to halt transmission — when screening programs stop, patients do not decrease, they simply become invisible. Experts project sub-Saharan African TB incidence could increase by 15-25% by the end of 2026. Malaria follows the same pattern, with deaths surging in regions where preventive medication distribution and insecticide-treated net provision have ceased, especially coinciding with rainy seasons.

PEPFAR's limited waiver continues, but its narrow scope means HIV prevention education, community-based screening, and programs for sexual minorities have already been halted. These services classified as "non-core" are actually critical to long-term HIV control — their absence may not show immediate effects, but will return as an explosion of new infections within 2-3 years. This is a time bomb.

In the medium term, over 6 months to 2 years, structural restructuring of global health governance becomes unavoidable. This crisis has exposed the fragility of US-dependent aid structures, making the transition to a distributed multilateral governance model an inevitable conversation. However, this transition takes time. Expanded World Bank IDA crisis response windows, enhanced Global Fund and Gavi roles, and EU-level health aid expansion are all under discussion, but actually mobilizing funds and running programs on the ground requires a minimum of 2-3 years.

Evaluating the most realistic scenarios: the bull case envisions the US Congress partially restoring PEPFAR funding after the 2026 midterms, the EU and Japan expanding emergency health aid, and the African Union launching its own health fund. Even in this optimistic scenario, additional deaths by 2030 are merely "reduced" to 3-4 million. The base case assumes the status quo continues — PEPFAR's limited waiver extends but does not expand, other donor nations increase aid only marginally, and developing countries' own health financing expansion remains sluggish. In this scenario, the Lancet's 9.4 million projection becomes reality. The bear case sees the Trump administration revoking even PEPFAR's waiver, UK and German aid cuts accelerating, and an economic downturn shrinking multilateral funding. Deaths could exceed 9.4 million, reaching 12-15 million.

Looking 2 to 5 years out, this crisis is likely to evolve from a health emergency into a geopolitical restructuring event. Political instability intensifying in countries with collapsed health systems will feed into migration crises, extremism proliferation, and security destabilization. Paradoxically, America's attempt to "save money" by cutting aid could inflate its own security costs. During the 2014 Ebola crisis, the US emergency deployment cost exceeded $5 billion — trying to save $7 billion annually in PEPFAR spending while risking a crisis that could cost ten times that is a losing calculation.

The global spread of drug-resistant HIV also represents a long-term threat. Drug-resistant viruses emerging from patients with interrupted treatment could render first-line therapies globally obsolete. WHO has already flagged first-line drug resistance exceeding 10% in some African nations — if this rate climbs to 20-30%, the entire global HIV treatment strategy requires fundamental redesign. This directly affects developed nations too.

The brain drain of health workers compounds the long-term damage. Tens of thousands of local medical professionals previously employed by USAID programs are emigrating or switching professions following program termination. An entire generation of trained nurses, doctors, epidemiologists, and lab technicians is vanishing within 2-3 years. Rebuilding this workforce requires a minimum of 10-15 years. Buildings can be reconstructed, but people cannot be produced simply by injecting funds.

Ultimately, this crisis is not about "the crisis of foreign aid" but about "the crisis of the global public goods management system." Responding to global health threats like pandemics, climate change, and antimicrobial resistance demands international cooperation, yet the largest donor nation's withdrawal is shaking the system to its foundations. This is not exclusively a developing world problem. Viruses do not check passports. COVID-19 proved that. If the next pandemic originates from Africa's crumbling health infrastructure, the entire world pays the price.
