The US has formally withdrawn from the World Health Organization after a one-year notice period, and it is leaving unpaid WHO obligations totaling hundreds of millions of dollars, including $278 million in dues, according to Stat News.

As of today, the US is no longer a member of the World Health Organization. The withdrawal followed a one-year period triggered when the US notified WHO of its intent to exit, as required by a 1948 joint resolution of Congress. says the Trump administration effectively cut ties immediately upon announcing the intent to withdraw, citing complaints about WHO’s COVID-19 response, dues payments, and alleged protection of China. The joint resolution required the US to pay its financial obligations in full before departing, but the administration has not done so. Stat News reported the US owed WHO $278 million in dues for the 2024–2025 membership period under WHO’s two-year budget cycle, and a State Department spokesperson said there was no way the US would pay the debt.
