U.S. Exits WHO, Triggering Global Health Shockwaves

The United States has officially withdrawn from the World Health Organization after being one of its founding members and largest funders since 1948.

While U.S. law allows withdrawal with a year’s notice, the country still owes outstanding dues, leaving legal questions unresolved as WHO leadership prepares to address the issue.

Health experts warn the decision could weaken global disease surveillance, reduce early access to critical data on influenza and emerging threats, and diminish America’s influence in shaping global health policy.

Although U.S. scientists may continue informal collaboration, the loss of federal-level coordination could slow vaccine planning and outbreak responses.

WHO officials stress their mission remains unchanged and that the U.S. is welcome to rejoin, but experts caution that the long-term consequences for global and domestic health may be difficult to undo.
