President Donald Trump’s decision to exit the World Health Organization means the U.N. agency is losing its biggest funder.

World Health Organization chief says agency already cutting back on hiring and travel with Trump withdrawal set to hit funding.

As part of a rash of executive orders completed on his first day back in the White House, President Donald Trump began the nation’s exit from the World Health Organization. Here, we explain how the withdrawal would work and what it would mean,

America’s departure will leave a gaping hole in the apex health organisation’s budget and operational capacity that will have worldwide repercussions.

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.

Tania Cernuschi, a WHO staff member of 10 years who has worked on improving vaccine access, said she thought of the campaign when she could not sleep after Trump's announcement.

WHO’s constitution, drafted in New York, doesn’t have a clear exit method for member states. A joint resolution by Congress in 1948 outlined that the U.S. can withdraw with one year's notice. This is contingent, however, on ensuring that its financial obligations to WHO “shall be met in full for the organization’s current fiscal year.”

By withdrawing from the World Health Organization and overhauling aid, Trump's new executive orders endanger Americans and the globe, researchers warn. The move also cedes U.S. power to other nations.

The World Health Organization is drawing up a list of reasons why the U.S. should remain in the WHO for its own good, two sources familiar with the process told Reuters, as part of an attempt by its supporters to lobby incoming President Donald Trump.

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.
