The U.S. exit from the World Health Organization (WHO) would undermine international efforts to fight against the COVID-19 pandemic that guarantee public health and save lives, officials and experts have warned. U.S. President Donald Trump said on May 29 that his country is "terminating" its relationship with the WHO. The announcement came days after the White House, in a letter to WHO Director-General Tedros Adhanom Ghebreyesus, threatened to make the temporary freeze of U.S. funding "permanent" and reconsider its membership in the organization. Experts have voiced their concerns over the U.S. decision, saying the move is undermining the irreplaceable role of the WHO in coordinating global efforts in combating COVID-19.
