The United States has formally moved to withdraw from the World Health Organisation (WHO), with the decision taking effect on January 22, 2026, following a one-year notice issued through an executive order by President Donald Trump.
Despite the effective date, uncertainty remains over the withdrawal, as the US reportedly owes the WHO approximately US$278 million in outstanding contributions, and the organisation has yet to officially acknowledge the exit.
The WHO Constitution does not explicitly provide a mechanism for member withdrawal or a formal approval process. As a result, the matter is expected to be deliberated by WHO member states during discussions scheduled for February.
