U.S. Withdrawal from the WHO: Implications and Reactions

The official withdrawal of the United States from the World Health Organization (WHO) became effective in late January 2026, following President Donald Trump's executive order issued on his inauguration day in January 2025. This decision has significant implications for global health governance and the operational capacity of the WHO.

The Trump administration cited perceived inequities in funding contributions as a primary reason for the U.S. exit. The administration argued that the U.S. disproportionately funded the WHO compared to other nations, particularly China, which contributes significantly less despite its larger population. Additionally, the administration criticized the WHO's handling of the COVID-19 pandemic, claiming a lack of accountability and transparency.

The U.S. has historically been the largest single contributor to the WHO, providing hundreds of millions of dollars annually. Its withdrawal is expected to create a funding shortfall of approximately $660 million for the 2026-2027 budget, which constitutes about 15% of the WHO's overall budget. In response to this financial crisis, the WHO announced plans to cut around 2,300 jobs, representing a quarter of its workforce, and to streamline its divisions from ten to four.

Public health experts have expressed concern over the U.S. withdrawal, emphasizing that it undermines global health efforts. The Infectious Diseases Society of America described the decision as a "shortsighted and misguided abandonment of our global health commitments." Experts warn that the U.S. departure will weaken the WHO's ability to manage infectious diseases and respond to public health emergencies, potentially leading to increased hospitalizations and fatalities from preventable diseases.

Dr. Tedros Adhanom Ghebreyesus, WHO's Director-General, acknowledged the challenges posed by the U.S. exit during the agency's executive board meeting. He stated, “Although we have faced a significant crisis in the past year, we have also viewed it as an opportunity for a leaner WHO to become more focused on its core mission.” He urged member states to increase their financial contributions to reduce reliance on voluntary donations.

The U.S. withdrawal has created legal complexities, particularly regarding its outstanding dues estimated at $260 million for the 2024-2025 fiscal year. The WHO's constitution does not explicitly outline withdrawal procedures, leading to uncertainties about the implications of Argentina's similar withdrawal notice. Both cases are expected to be addressed in upcoming meetings.

While the U.S. has officially exited the WHO, there are indications that future administrations may reconsider this decision. The WHO has expressed a desire to engage with the U.S. and hopes for a potential return. Meanwhile, individual states like California are exploring alternative avenues for participation in global health initiatives, indicating a potential shift in how U.S. public health policy may evolve in the absence of federal leadership within the WHO framework.
