More than half of Americans believe the U.S. benefits from its membership in the WHO. As of April 2024, 25% of U.S. adults say the country benefits a great deal from its membership, while about one-third say it benefits a fair amount. Conversely, 38% say the U.S. does not benefit much or at all from WHO membership.

The World Health Organization is shaped by its members: 194 countries that set health priorities and make agreements about how to share critical data, treatments, and vaccines during international emergencies.

Public health experts say the United States’ departure could cripple the WHO’s operations or leave an opening for China to assume greater control over the agency.

Public health experts say U.S. withdrawal from the W.H.O. would undermine the nation’s standing as a global health leader and make it harder to fight the next pandemic.

The United States will leave the World Health Organization, President Donald Trump said on Monday, saying the global health agency had mishandled the COVID-19 pandemic and other international health crises.
