<h1>WHO Chief Urges Nations to Advocate Against U.S. Withdrawal, Citing Loss of Critical Global Health Data and Financial Impact</h1> The World Health Organization's chief urged nations to pressure the U.S. to reconsider its withdrawal from the agency, emphasizing the loss of critical global health information. The U.S., WHO's largest donor, contributes significantly to programs like polio eradication and tuberculosis. The withdrawal risks a financial crisis for WHO, potentially affecting health responses in regions like the Middle East and Africa. WHO Director-General Tedros Adhanom Ghebreyesus argued the U.S. exit was not about funding but the loss of outbreak data. Experts noted the U.S. benefits from WHO's global health intelligence, which is crucial for American public health.
