On January 22, 2026, the United States government, under the leadership of President Donald Trump and the Department of Health and Human Services (HHS), officially completed its withdrawal from the World Health Organization (WHO). This move ended over 78 years of U.S. membership in the global health agency that was first established in 1948. The decision has drawn significant international attention, strong reactions from public health experts, and widespread debate among policymakers and healthcare professionals alike.
This blog offers a clear and comprehensive look at the U.S. exit from WHO, its background, the arguments from both supporters and critics, and potential implications for public health cooperation and disease preparedness worldwide.
After President Trump signed Executive Order 14155, titled Withdrawing the United States from the World Health Organization, on January 20, 2025, the U.S. began the formal process of exiting WHO. By January 22, 2026, exactly one year later, the United States completed the withdrawal process, officially ending its decades‑long partnership.
The action involved the United States:
This effectively removed the United States from membership in the WHO and shifted the way the country engages with global health initiatives.
Officials from the Trump administration and the HHS justified the decision by criticizing WHO’s performance, especially during the COVID‑19 pandemic. They argued that WHO:
In statements prior to the official withdrawal, U.S. Health Secretary Robert F. Kennedy Jr. said that the organization had become “mired in bureaucratic bloat, entrenched paradigms, conflicts of interest, and international power politics,” and called for new forms of global health cooperation outside traditional WHO structures.
The U.S. government also announced it would pursue direct bilateral collaboration with other countries and global partners, while emphasizing domestic leadership through agencies like the U.S. Centers for Disease Control and Prevention (CDC) and the National Institutes of Health (NIH).
The World Health Organization issued a formal statement expressing regret over the U.S. withdrawal. WHO emphasized the United States’ historical contributions to global health achievements, including the eradication of smallpox and progress in controlling diseases such as polio, HIV, Ebola, and malaria.
In its statement, WHO also said it disagreed with the U.S. characterization of its pandemic response, arguing that the organization acted with timeliness and transparency, shared data with countries worldwide, and advised governments based on the best available scientific evidence.
The organization stated that it hopes the United States will return to active participation in the future, and reaffirmed its commitment to global public health cooperation across all nations.
WHO Director‑General Tedros Adhanom Ghebreyesus publicly described the U.S. reasoning as “untrue,” and warned that the withdrawal could make both the United States and the world “less safe.” He emphasized that WHO acts impartially to serve all member states and noted the importance of shared disease surveillance, health research, and global coordination in reducing the impacts of outbreaks.
Supporters of the U.S. withdrawal argue that WHO needed structural reform and that current global health cooperation models were overly bureaucratic, lacked accountability, and did not sufficiently protect national sovereignty. Some officials have framed the move as a reassertion of American leadership in global health via direct, efficient partnerships rather than large multilateral institutions.
They also point to the potential for the United States and its partners to build new frameworks for disease surveillance, research, and response that better align with national priorities.
Many public health experts and scientists have been highly critical of the decision. Their concerns include:
Critics often emphasize that infectious agents do not respect national borders, making cooperation and coordination through international platforms like WHO fundamentally important for both domestic and global public health readiness.
While the United States has completed its formal withdrawal, financial obligations and unpaid assessed contributions to WHO remain an issue. WHO has noted that the U.S. still owes funds for past contributions, and these dues are expected to be discussed by the WHO Executive Board and the World Health Assembly.
The financial gap left by the United States, historically one of the largest contributors to WHO’s budget, could also affect ongoing global health programs aimed at disease prevention, vaccination campaigns, and health system strengthening in lower‑income countries.
One of the key roles of WHO is coordinating global surveillance of infectious diseases, including influenza strain monitoring that guides vaccine development each season. The lack of full U.S. participation could:
WHO supports vaccination efforts worldwide, including those targeting polio and other preventable diseases. Loss of funding and direct collaboration from the United States could:
Collaborative research facilitated by WHO, such as sharing pathogen genomes and coordinating clinical studies, has been vital in addressing global health challenges. Reduced U.S. involvement may:
In response to the federal government’s decision, some U.S. states, organizations, and health networks have taken independent action to maintain collaborative ties with WHO or similar global health efforts. For example, California announced plans to join WHO’s Global Outbreak Alert & Response Network (GOARN), signaling a subnational commitment to international public health cooperation even without formal federal membership.
This reflects a broader debate within the United States about the role of state governments and private health institutions in global health engagement.
The withdrawal may shift global power balances in health diplomacy. Countries like China, Russia, and India could see increased influence within WHO and other international health forums, reshaping how global health policies and priorities are set.
Critics of the U.S. withdrawal also warn that losing a major stakeholder from WHO may weaken global readiness for future pandemics, biothreats, and other transnational health emergencies.
The United States’ official withdrawal from the World Health Organization in 2026 marks a historic and controversial shift in global health collaboration. Whether this leads to stronger, more flexible new frameworks or creates gaps in global disease preparedness remains to be seen.
What is certain is that this move has generated intense debate among policymakers, experts, and the global health community. It raises serious questions about the future of international cooperation on health threats and underscores the importance of shared scientific knowledge and coordinated responses to protect populations around the world.
