United States Completes Exit from WHO, Leaves Unpaid Dues and Raises Global Health Concerns

The United States has formally completed its withdrawal from the World Health Organization (WHO), ending decades of participation in the United Nations’ global health body and leaving behind unpaid financial commitments running into hundreds of millions of dollars. The move, which took effect this week, marks a significant shift in global health governance and has prompted widespread concern among public health experts worldwide.

According to officials in Washington, all financial contributions to the WHO have now been halted, and American personnel have been withdrawn from the organisation’s headquarters and regional offices. The US has also ceased involvement in WHO-led committees, technical groups, and leadership bodies, effectively severing institutional ties with the agency.

Unpaid Financial Obligations

Despite the formal exit, the United States has not cleared outstanding membership dues for recent years. Estimates of the unpaid amount vary, but international health officials place the figure at approximately $260 million, covering assessed contributions and other obligations. US authorities, however, have contested the need to settle these dues before withdrawal.

Senior officials from the US health administration stated that there is no legal requirement mandating the settlement of outstanding payments prior to exiting the organisation. While a longstanding Congressional resolution requires advance notice and payment of dues, the administration has maintained that this does not impose a binding obligation under current circumstances.

This position has sparked debate among legal experts and international health policymakers, who warn that unresolved financial commitments could complicate future cooperation between the US and global health institutions.

Background to the Decision

The decision to withdraw was initiated through an executive order signed at the start of President Donald Trump’s second term. The administration cited concerns over the WHO’s handling of the COVID-19 pandemic, the pace of internal reforms, and what it described as insufficient independence from political influence.

While criticism of the WHO has been voiced by several governments in recent years, the US move is seen as the most consequential due to the country’s long-standing role as the organisation’s largest financial contributor and one of its most influential members.

Between 2022 and 2023, the United States contributed close to $1.3 billion to the WHO through assessed dues and voluntary funding. This financial support played a major role in programmes related to disease surveillance, emergency response, vaccine distribution, and health system strengthening in low- and middle-income countries.

Impact on Global Health Efforts

Health experts have warned that the US exit could have far-reaching implications for global health initiatives. The WHO coordinates international responses to disease outbreaks, sets global health standards, and supports countries with limited healthcare infrastructure. The loss of US funding and technical participation is expected to affect several ongoing programmes.

Initiatives targeting polio eradication, maternal and child health, and research on emerging infectious diseases could face funding gaps and operational challenges. In addition, the withdrawal means that American scientists and public health agencies will no longer have direct access to certain global disease surveillance networks coordinated by the WHO.

One area of particular concern is influenza monitoring. Participation in WHO-led influenza data-sharing systems helps countries make timely decisions on vaccine composition and preparedness measures. Reduced access to such data could slow response times during future outbreaks.

Reactions from the Health Community

Leaders from medical and public health organisations have expressed concern over the US decision, describing it as potentially harmful to international cooperation in health emergencies. Several experts have cautioned that global health threats do not respect national borders, making coordinated action essential.

International health law specialists have also pointed out that the departure of a major scientific and financial contributor could weaken collective capacity to detect and respond to new health risks. At the same time, they note that the WHO will need to explore alternative funding arrangements to sustain critical programmes.

WHO Without Its Largest Donor

With the US no longer part of the organisation, the WHO faces the challenge of adjusting its budget and operational priorities. Nearly every country in the world remains a member of the agency, but the absence of its largest historical donor creates uncertainty about long-term funding stability.

WHO officials have reiterated the organisation’s commitment to its mandate and ongoing programmes, while acknowledging that the funding gap will require support from other member states and partners.

Looking Ahead

The US withdrawal from the WHO represents a major development in global health diplomacy. While the long-term consequences will unfold over time, the immediate effects include reduced funding, disrupted collaboration, and increased pressure on remaining member states to fill the gap.

As global health challenges continue to evolve—from infectious disease outbreaks to climate-related health risks—the absence of one of the world’s largest economies from the WHO raises important questions about the future of coordinated international health responses. For now, health experts stress the need for dialogue, cooperation, and renewed commitment to shared global health goals.
