The World Health Organization (WHO) has formally expressed its deep regret following the United States’ notification of its intent to withdraw from the organization. As a founding member and long-standing contributor to the agency, the United States has played an instrumental role in some of the most significant public health milestones of the last century. From the monumental success of the smallpox eradication program to ongoing, complex efforts to combat polio, HIV, Ebola, influenza, tuberculosis, and malaria, the American partnership has been a cornerstone of global health security. The withdrawal, according to the WHO, is a decision that leaves both the United States and the broader international community more vulnerable to shared health threats.
The notification of withdrawal has initiated a formal procedural timeline. These matters are slated to be addressed by the WHO Executive Board during its regular session beginning on February 2, with further deliberations scheduled for the World Health Assembly’s annual meeting in May 2026. This period of transition raises significant questions about the future of international cooperation in the face of antimicrobial resistance, food safety, and the emergence of new, neglected tropical diseases that require a unified global response.
The rift between the WHO and the U.S. government stems from sharp disagreements regarding the agency’s performance and governance. The U.S. administration has publicly accused the WHO of being "trashed and tarnished," alleging that the organization has been compromised in its independence and has insulted the United States. The WHO, however, has firmly rejected these characterizations. In a statement addressing the diplomatic friction, the organization emphasized that it has consistently sought to engage with the United States in good faith, maintaining a policy of full respect for American sovereignty, just as it does with all 194 of its Member States.
Central to the United States’ decision to withdraw were accusations regarding the WHO’s handling of the COVID-19 pandemic. The U.S. government specifically cited alleged failures in information sharing, claiming that the WHO obstructed the timely dissemination of critical data and attempted to conceal shortcomings. In its defense, the WHO maintains that while no organization—or government—managed the unprecedented crisis without error, it stands by its documented response. The agency asserts that throughout the pandemic, it acted with urgency, transparency, and adherence to the best available evidence, providing guidance that was intended to support, rather than dictate, national policy.
A point of contention often raised during the pandemic was the nature of the WHO’s recommendations. The agency clarifies that while it consistently advocated for the use of masks, vaccination, and physical distancing as effective public health tools, it never at any stage issued recommendations for vaccine mandates, mask mandates, or state-ordered lockdowns. The WHO maintains that its role is to support sovereign governments, providing the technical expertise necessary for those governments to make informed decisions they believe are in the best interests of their own populations. Ultimately, the WHO argues, the responsibility for specific domestic policy measures rested entirely with the individual nations.
The timeline of the WHO’s initial COVID-19 response has been a subject of significant scrutiny. The organization reports that immediately upon receiving the first notifications of a cluster of cases involving "pneumonia of unknown cause" in Wuhan, China, on December 31, 2019, it requested further information from Chinese authorities and activated its emergency incident management system. By January 11, 2020, when the first death was reported in China, the WHO had already disseminated alerts through formal international channels, public statements, and digital media. It had also convened a group of global experts and published comprehensive guidance to assist countries in fortifying their health systems.
When the WHO Director-General declared COVID-19 a Public Health Emergency of International Concern (PHEIC) on January 30, 2020—the highest level of alert under international health law—there were fewer than 100 reported cases outside of China, and zero reported deaths globally. Throughout those critical early weeks, the Director-General repeatedly urged nations to take immediate, decisive action. With warnings such as "the window of opportunity is closing" and "this is not a drill," the agency attempted to galvanize a global response to what it labeled "public enemy number one."
In the wake of the pandemic, the WHO has been the subject of multiple independent reviews. In response to these assessments, the organization has taken proactive steps to strengthen its operational performance and improve its ability to support countries in bolstering their own pandemic preparedness. The systems currently managed by the WHO—which operate on a 24/7 basis—are designed to provide early warnings and technical support that benefit all Member States, including the United States.
Regarding accusations that the WHO has pursued a "politicized, bureaucratic agenda" steered by nations hostile to American interests, the agency maintains that such claims are factually incorrect. As a specialized agency of the United Nations, the WHO is governed by 194 Member States. Its constitutional mandate is to serve all nations with impartiality, acting without fear or favor, and remaining committed to the principle that the highest attainable standard of health is a fundamental right for every human being.
Despite the current diplomatic impasse, the WHO continues to emphasize the value of multilateral cooperation. Last year, Member States demonstrated a collective commitment to global health security by adopting the WHO Pandemic Agreement. Once ratified, this landmark instrument of international law is designed to create a more robust framework for preventing and responding to future pandemics. Furthermore, negotiations are currently underway regarding an annex to this agreement, known as the Pathogen Access and Benefit Sharing (PABS) system. If successfully adopted, the PABS system will facilitate the rapid detection of pathogens with pandemic potential and ensure equitable, timely access to essential vaccines, therapeutics, and diagnostics for all regions of the world.
The WHO expressed hope that, in the future, the United States will find a path back to active participation within the organization. In the interim, the agency remains steadfast in its core mission. It continues to collaborate with countries across the globe to navigate the world’s most pressing health threats, both communicable and noncommunicable. The agency’s leadership has reiterated that its constitutional mandate remains the priority: to work tirelessly toward the goal of ensuring that all people, regardless of their nationality or political climate, have access to the highest possible standard of health. The coming months will be critical as the WHO Executive Board and the World Health Assembly deliberate on the implications of this withdrawal, yet the organization remains focused on maintaining the continuity of its essential global health programs.
