- The Hidden Costs of America’s Exit from the WHO - 2 March, 2026
Overview
The U.S. has left the World Health Organization, signaling a shift in U.S. policy and approach towards international health cooperation. The U.S. left the WHO primarily over disagreements about pandemic response, governance, and contributions. This withdrawal affects global disease monitoring, reduces U.S. influence on health policy, creates financial strain for the WHO, and carries potential risks for both international and U.S. public health and diplomacy.
Introduction
On January 22, 2026, the United States formally left the World Health Organization (WHO) after President Trump signed executive order 14155.
Actions taken to depart the WHO include:
- U.S. personnel and contractors have been recalled from the WHO offices worldwide.
- U.S. government funding has been terminated.
- The U.S. has ceased official participation in WHO committees, working groups, and governance structures.
The decision behind departing from WHO was the handling of the COVID-19 pandemic; the U.S. claimed WHO was not sufficiently independent from China; financial disparity of U.S. contributions; and a view that the WHO is incapable of necessary structural improvements.
In response, the WHO has rejected these claims. Regarding the debt dispute, WHO has indicated that the U.S. created a $278 million debt for past due membership dues in 2024 and 2025. Consequently, WHO faces a severe financial crisis with the loss of funding forced the WHO to reduce its 2026-2027 budget by over $1 billion, threatening the global influenza surveillance system which is crucial for vaccine development. As a result, WHO has moved to reduce costs, cut approximately 25% of its workforce by the summer of 2026, and shift away from over-reliance on major donors. There is also a shift towards a more equitable governance structure with countries in Africa, Asia, and Latin America being more vocal.
The loss of U.S. funding as well as expertise will have an affect on the WHO’s ability to operate. Despite U.S. criticism of the lack of reform, the WHO is revising International Health Regulations (IHR) and pushing forward with initiatives live the WHO Pandemic Agreement to strengthen future pandemic readiness.
Consequences for Global Health Cooperation
With a loss of Access to Global Health Data and Coordinated Systems, domestic health institutions such as the CDC and National Institutes of Health loose collaborative opportunities and global data access offered from WHO. For example, the freeze on United States Agency for International Development (USAID) Malaria Vaccine Development Program has halted vaccine trials and stunted progress. The international weakened infrastructure exposes the U.S. to health threats by slowing detection and response.
A major consequence for global health cooperation is the U.S. withdrawal from the WHO’s Global Influenza Surveillance and Response System, which has been in operation since 1952. As annual flu vaccines are developed a year in advance using global data, this will affect the U.S. ability to create vaccines that can match predicted flu strands each year. This could lead to differences between WHO and U.S. authorities recommendations.
U.S. Role in Global Health Cooperation Moving Forward
For the US, withdrawal will result in less influence on global health policies and less alignment with new international health regulations. The U.S. departure has resulted in a change in WHO leadership with China becoming the next largest contributor. Severing ties with a critical multilateral framework removes U.S. influence in International Health Regulations and shaping the Pandemic Accord, which is essential to coordinated responses to global health threats.
After leaving WHO, the U.S. has adopted a bilateral approach to international health agreements. This has included working directly with private entities, countries, and NGOs. As of February 2026, the U.S. has signed 16 country to country agreements. The majority of these agreements have been in sub-Saharan Africa and emphasize increased co-investment, self-reliance, and targeted funding for pandemic preparedness, HIV/AIDS, and infectious diseases.
In addition, many states are taking individualized action. For example, California has formed the West Coast Health Alliance with other states and planned to join the WHO’s Global Outbreak Alert & Response Network. This indicates an element of friction between Federal and State approach to collaboration with WHO.
Looking towards the future – Now that the U.S. has left the WHO, future international health cooperation doesn’t disappear but it changes shape. The U.S. will likely rely on a mix of bilateral ties, alternative institutions, and domestic capacity to fill the gap.
