US to formally exit World Health Organization on Thursday

The United States is due to formally leave the World Health Organization on Thursday, a year after President Donald Trump gave notice through an executive order on his first day in office in 2025. U.S. law requires one year's notice and payment of $260 million in outstanding fees; the WHO says dues for 2024 and 2025 remain unpaid. Washington contributed about 18% of WHO funding. Facing a budget crisis, the agency will cut about a quarter of its staff by mid-year.

Analysts’ view opinion

AI Strategic Affairs Analyst

This exit is not merely a public-health decision — it fits a broader strategic pattern of American disengagement from multilateral institutions. Disease surveillance and information-sharing networks sit squarely inside the biosecurity domain; with roughly 18% of funding gone and a quarter of staff to be cut, experts warn that global early-warning capacity could be weakened. Washington's counter-argument is also on the table: it says the agency failed to contain, manage and share information at enormous cost, and that American taxpayers have already paid more than enough — in effect an accountability-for-funding argument.

The departure of the single largest funder from the world's health surveillance architecture is a strategic signal to every government that treats health security as national security.
The central question is who fills the funding and influence vacuum — other major states, regional blocs or private philanthropies could expand their role, though this story does not establish that any of them will.
A legal expert quoted in the story argues that leaving without paying the $260 million owed violates U.S. law, raising the question of whether this becomes a precedent for other international obligations.
The U.S. side of the case is substantive: the State Department cites the agency's pandemic-era failures as having cost trillions, and says the president used his authority to pause future transfers of funds and resources.
How information-sharing with the agency will work from here is explicitly unclear, and that ambiguity could slow response times to cross-border outbreaks.

What to watch — Watch the WHO executive board in February, where member states are set to discuss how the U.S. departure and the resulting budget gap are handled — and whether any alternative information-sharing arrangement with Washington emerges.

The story does not establish whether the arrears will ever be paid, whether the withdrawal will face a legal challenge, or which actor, if any, will step in to cover the shortfall.

The brief

Context

The United States is set to formally leave the World Health Organization, the United Nations' health agency, a year after President Donald Trump signed an executive order announcing withdrawal on the first day of his presidency in 2025. U.S. law requires one year's notice and settlement of all outstanding dues before an exit; the WHO says $260 million in fees for 2024 and 2025 remain unpaid. Washington has historically been the WHO's largest funder, providing about 18% of its overall funding, and its departure has triggered a budget crisis at the agency. Global health experts, WHO Director General Tedros Adhanom Ghebreyesus and philanthropist Bill Gates have urged a rethink, but a quick return is seen as unlikely.

Key facts

The U.S. is due to officially exit the World Health Organization on Thursday, one year after notice was given.
President Trump gave notice of withdrawal via an executive order on the first day of his presidency in 2025.
U.S. law requires one-year notice and payment of all outstanding fees; the WHO says $260 million in fees are owed.
The WHO says the U.S. has not yet paid its dues for 2024 and 2025.
Washington traditionally contributed around 18% of the WHO's overall funding, its biggest financial backer.
The budget crisis has led the WHO to halve its management team and scale back work across the agency.
The WHO will shed around a quarter of its staff by the middle of this year.
WHO member states are set to discuss the U.S. departure and its handling at the executive board in February.

Timeline

First day of Trump's presidency, 2025Trump signs an executive order giving notice that the U.S. will quit the WHO.
Over the following yearGlobal health experts urge a rethink; the WHO cuts management in half and reduces budgets; WHO says it kept sharing information with the U.S.
Earlier this monthWHO Director General Tedros says he hopes the U.S. will reconsider and rejoin, calling withdrawal a loss for both sides.
At Davos (recent)Bill Gates tells Reuters he does not expect the U.S. to return to the WHO in the near future.
ThursdayU.S. formally exits the WHO; State Department says the president paused future transfer of U.S. funds, support or resources.
FebruaryWHO executive board to discuss the U.S. departure and how it will be handled.

Who has a stake

World Health Organization — Loses its biggest funder (about 18% of funding), faces a budgetary crisis, management halved and a quarter of staff to go by mid-year.
United States government — Says WHO's failure to contain, manage and share information cost it trillions; has paused future funds but faces claims it is violating U.S. law on unpaid dues.
Tedros Adhanom Ghebreyesus, WHO Director General — Publicly hopes the U.S. reconsiders, calling withdrawal a loss for the U.S. and the world.
WHO member states — Must decide at the February executive board how to handle the U.S. departure and the resulting funding gap.
Gates Foundation / Bill Gates — A major funder of global health and some WHO work; Gates says the world needs the WHO but expects no quick U.S. return.
Lawrence Gostin, O'Neill Institute for Global Health Law, Georgetown University — Argues non-payment is a clear violation of U.S. law but that Trump is highly likely to get away with it.
Bloomberg Philanthropies — Warns U.S. withdrawal could weaken systems and collaborations the world relies on to detect, prevent and respond to health threats.

Why it matters

The exit of the WHO's largest funder forces deep cuts at the agency that coordinates global detection of and response to disease threats, with experts warning of risks to U.S., WHO and worldwide health security. It also raises questions about whether a government can walk away from binding financial obligations without consequence, and about who fills the funding gap left behind.

UPSC angle

The WHO is the United Nations' specialised health agency; its Director General is Tedros Adhanom Ghebreyesus.
U.S. law requires one-year notice and payment of all outstanding fees before leaving the WHO.
The U.S. owes the WHO $260 million in fees, including dues for 2024 and 2025.
The U.S. contributed around 18% of overall WHO funding, its largest backer.
The WHO plans to cut around a quarter of its staff by mid-year and has halved its management team.
The WHO executive board will take up the U.S. departure in February.

Mains framing

The formal U.S. exit from the WHO illustrates how heavily multilateral health governance depends on a handful of funders: with Washington supplying around 18% of the agency's overall funding, its withdrawal has forced the WHO to halve its management team, cut budgets across the organisation and plan to shed about a quarter of its staff by mid-year. The U.S. justification, articulated by the State Department, is that the WHO's failure to contain, manage and share information cost America trillions of dollars, and the president has paused future transfers of funds, support and resources. Critics counter on two grounds: legally, U.S. law requires one-year notice plus payment of outstanding fees, and $260 million for 2024 and 2025 remains unpaid, which Lawrence Gostin calls a clear violation that Trump is likely to get away with; and functionally, as Bloomberg Philanthropies' Kelly Henning warns, the departure could weaken the systems and collaborations the world relies on to detect, prevent and respond to health threats. With Bill Gates and Tedros both signalling that a quick U.S. return is unlikely, the way forward, on the source's evidence, runs through the WHO executive board's February discussion on handling the departure, continued information-sharing arrangements whose shape remains unclear, and reliance on philanthropic and member-state support.

Practice questions

Examine the implications of the United States' withdrawal from the World Health Organization for global health security and for the financing of multilateral institutions.
Heavy dependence on a few large donors is the central weakness of global health governance. Discuss with reference to the WHO's budget crisis following the U.S. exit.
What legal obligations did U.S. law impose before withdrawal from the WHO, and what does non-compliance suggest about the enforceability of commitments to international organisations?
