The United States has formally withdrawn from the World Health Organization (WHO), removing itself as one of the UN agency’s largest donors and a key participant in global health initiatives.
The decision stems from an executive order signed by US President Donald Trump a year ago, after he repeatedly criticised the WHO for being overly “China-centric” during the Covid-19 pandemic. The US Department of Health and Human Services said the withdrawal was due to the WHO’s alleged mishandling of the pandemic, its inability to implement meaningful reforms, and political influence from certain member states.
WHO Director-General Tedros Adhanom Ghebreyesus rejected the US claims, saying the withdrawal is a “loss for both the United States and the world.” The organisation highlighted its global contributions, including efforts to eradicate polio, combat HIV and AIDS, reduce maternal mortality, and enforce its international treaty on tobacco control.
Following the pandemic, WHO member states worked on an international pandemic treaty to ensure fair sharing of vaccines and treatments and strengthen preparedness for future outbreaks. The treaty, finalised in April 2025, was agreed upon by all member states except the US.
Traditionally, the United States has been one of the largest financial contributors to the WHO, but Washington did not pay its membership fees for 2024 and 2025, causing significant job losses within the organisation. While WHO lawyers maintain that the US is obliged to pay the arrears—estimated at $260 million—Washington has refused, stating there is no reason to do so.
As part of the withdrawal, all US government funding to the WHO has been terminated, US personnel and contractors recalled from Geneva headquarters and offices worldwide, and hundreds of engagements with the agency have been suspended or discontinued. US Health Secretary Robert F. Kennedy and Secretary of State Marco Rubio said in a joint statement that the WHO “tarnished and trashed everything that America has done for it” and “abandoned its core mission,” acting against US interests. They added that future US engagement with the WHO will be limited strictly to safeguard the health and safety of Americans.
Officials noted that the US will continue disease surveillance and pathogen-sharing programs through bilateral relationships with other countries, but they did not specify which countries or partnerships have been established so far. In response to questions about US participation in global health initiatives like polio and HIV programmes, officials said partnerships would continue through NGOs and faith-based groups, though no specific arrangements have been disclosed. US engagement in global flu vaccine development and information-sharing remains uncertain.
After Trump signed the withdrawal order at the start of his second term, the WHO expressed hope that the US would reconsider, stating that “the WHO and the USA have saved countless lives and protected Americans and all people from health threats.” The agency said reconsideration would serve the “health and well-being of millions worldwide.”
The WHO confirmed on Friday that the US withdrawal would be discussed during its upcoming board meeting scheduled from February 2-7. Its secretariat said it will act according to the guidance provided by its governing bodies.
The US exit could remove nearly one-fifth of the WHO’s budget. The defunding and withdrawal come amid criticism of pandemic responses worldwide, including in highly developed countries like the US and the UK, where delays in imposing lockdowns and mask mandates contributed to rapid virus spread. Drew Altman, former US public health official, said the federal government’s inconsistent Covid-19 guidance, politicisation of policy, and failure to implement nationwide preventive measures contributed to one of the highest death rates in the world.
A 2020 study in the British Medical Journal accused the Trump administration of failing to provide national guidance and allowing state-level responses to diverge along political lines. Another research paper published in the UN National Library of Medicine labelled the US federal response as “slow and mismanaged.”
The US withdrawal marks a significant moment for global health governance, highlighting tensions between national interests and multilateral cooperation in pandemic preparedness and response.
