WASHINGTON — The United States formally exited the World Health Organization on January 22, 2026, concluding a one-year withdrawal process initiated by President Donald Trump’s administration that has stirred debate among public health and business leaders worldwide.
The move ends more than seven decades of U.S. membership in the global health body and removes America from a leading role in international health coordination just as global markets and supply chains navigate pandemic recovery and prepare for future threats.
Executive Order Triggers Withdrawal
On January 20, 2025, President Trump signed Executive Order 14155, titled “Withdrawing the United States from the World Health Organization,” directing the U.S. government to begin the formal process of leaving the Geneva-based United Nations agency.
The order cited concerns over WHO’s handling of the COVID-19 pandemic, claims of insufficient reforms and “unfairly onerous” financial demands on the United States.
Under the WHO constitution, a member state’s withdrawal becomes effective 12 months after formal notice to the United Nations, setting the effective date at January 22, 2026.
Parting Words From WHO
The WHO responded early in 2025 with a public statement saying it “regrets the announcement that the United States of America intends to withdraw from the organization,” emphasizing the agency’s role in disease prevention and response, global health systems strengthening and collaboration.
WHO also highlighted its long working partnership with the United States, including joint campaigns against smallpox and progress against polio, and expressed hope that the U.S. would reconsider its decision.
Financial Impact and U.S. Funding History
The United States has been the top financial contributor to the WHO, providing US$1.284 billion during the 2022-2023 biennium, according to WHO data. Statista analysis shows the U.S. share of total funding was roughly 12–15 percent of the WHO’s budget in that period.
As part of the withdrawal process, U.S. officials also halted future transfer of funds and paused participation in WHO programs.
WHO Adjusts to Funding Loss
Anticipating the departure, WHO leaders began cost-saving measures in early 2025, including hiring freezes and reduced travel and operations, as the agency prepares for the loss of a major funding stream.
With the U.S. exit now effective, the organization faces a tighter financial outlook and pressure to expand partnerships and alternative funding sources to maintain essential health surveillance and disease response functions.
Business and Health Sector Concerns
Analysts say the withdrawal has implications for global health governance and markets connected to health security.
Businesses that rely on globally coordinated disease monitoring and prevention frameworks may face higher uncertainty in planning for pandemics or cross-border health risks.
Experts also note that the U.S. departure could affect access to global health data that underpins pharmaceutical development, travel policy risk assessments and international supply chain resilience.
While specific quantified impacts are still emerging, policy analysts say the loss of U.S. influence and funding may slow coordinated responses to future outbreaks.
