WASHINGTON (AP) 鈥 President Donald Trump used one of the flurry of executive actions that he issued on his first day back in the White House to begin the process of from the for the second time in less than five years 鈥 a move many scientists fear could roll back decadeslong gains made in fighting diseases like AIDS, malaria and tuberculosis.
Experts have also cautioned that withdrawing from the organization could weaken the world鈥檚 defenses against new outbreaks capable of triggering pandemics.
Here鈥檚 a look at what Trump鈥檚 decision means:
What happened?
During the first Oval Office appearance of his second term, Trump signed an executive order detailing how the withdrawal process might begin.
鈥淥oh," Trump exclaimed as he was handed the action to sign. "That鈥檚 a big one!鈥
His move calls for pausing the future transfer of U.S. government funds to the organization, recalling and reassigning federal personnel and contractors working with WHO and calls on officials to 鈥渋dentify credible and transparent United States and international partners to assume necessary activities previously undertaken by鈥 WHO.
This isn鈥檛 the first time Trump has tried to sever ties with WHO. In , several months after WHO declared COVID-19 to be and as cases surged globally, Trump鈥檚 administration officially notified U.N. Secretary-General Antonio Guterres that the U.S. was planning to pull out of WHO, suspending funding to the agency.
President Joe Biden on his first day in office in January 2021 鈥 only to have Trump essentially revive it on his first day back at the White House.
What is WHO and does this really matter?
It is the U.N.鈥檚 specialized health agency and is mandated to coordinate the world鈥檚 response to global health threats, including outbreaks of , and . It also provides technical assistance to poorer countries, supplies and treatments and sets guidelines for hundreds of health conditions, including mental health and cancer.
鈥淎 U.S. withdrawal from WHO would make the world far less healthy and safe,鈥 said Lawrence Gostin, director of the WHO Collaborating Center on Global Health Law at Georgetown University. He said in an email that losing American resources would devastate WHO's global surveillance and epidemic response efforts.
New Zealand's former prime minister Helen Clark said it wasn't in American interests to pull out of the agency now, particularly given the 鈥済hastly proposition鈥 that the increased spread of bird flu there might turn into a pandemic.
She described Trump as 鈥渁 disruptor鈥 and said the loss of American funding to WHO would cause 鈥渜uite a substantial dent鈥 to the agency.
Can Trump really withdraw the US from WHO?
Yes, as long as he gets the approval of Congress and the U.S. meets its financial obligations to WHO for the current fiscal year. The U.S. joined WHO via a 1948 joint resolution passed by both chambers of Congress, which has subsequently been supported by all administrations. The resolution requires the U.S. to provide a one-year notice period should it decide to leave WHO.
What does this mean for WHO?
It鈥檚 extremely bad. The U.S. has historically been among WHO鈥檚 biggest donors, providing the U.N. health agency not only with hundreds of millions of dollars, but also hundreds of staffers with specialized public health expertise.
In the last decade, the U.S. has given WHO about $160 million to $815 million every year. WHO鈥檚 yearly budget is about $2 billion to $3 billion. Losing U.S. funding could cripple numerous global health initiatives, including the effort to eradicate polio, maternal and child health programs, and research to identify new viral threats.
American agencies that work with WHO would also suffer, including the CDC. Leaving WHO would exclude the U.S. from WHO-coordinated initiatives, like determining the yearly composition of flu vaccines and quick access to genetic databases run by WHO, which could stall attempts to produce immunizations and medicines.
Why is Trump withdrawing the US from WHO?
At a September campaign rally, Trump said he would 鈥渢ake on the corruption鈥 at WHO and other public health institutions that he said were 鈥渄ominated鈥 by corporate power and China.
His executive order Monday said the U.S. was withdrawing from WHO 鈥渄ue to the organization鈥檚 mishandling of the COVID-19 pandemic that arose out of Wuhan, China and other global health crises鈥 and cited the agency鈥檚 鈥渇ailure to adopt urgently needed reforms鈥 and its 鈥渋nability to demonstrate independence from the inappropriate political influence of WHO member states.鈥
WHO made several costly mistakes during the pandemic, including advising people against and asserting that COVID-19 was not airborne. The agency only last year that the virus is indeed spread in the air.
During its efforts to stop COVID-19, WHO also dealt with the in its history, when media reports revealed that dozens of Congolese women had been sexually harassed or assaulted by health responders working to contain Ebola. The AP found senior managers were of some instances of sexual abuse when they occurred in 2019 but did little to stop them or punish perpetrators.
What has WHO said?
In a statement Tuesday, WHO said it 鈥渞egrets鈥 Trump's announcement.
鈥淲e hope the United States will reconsider and we look forward to engaging in constructive dialogue to maintain the partnership between the USA and WHO,鈥 the organization said.
鈥淔or over seven decades, WHO and the USA have saved countless lives and protected Americans and all people from health threats. Together, we ended smallpox, and together we have brought to the brink of eradication,鈥 WHO said.
At a Geneva news briefing on Tuesday, WHO spokesperson Tarik Jasarevic said the U.S. contributed 18% of WHO's budget in 2023, making it the single biggest donor that year. He declined to say what the U.S. withdrawal might mean for WHO.
