Donald Trump has been sworn in as the 47th President of the United States, with his first speech after he returned to office as "The golden age of America begins right now." Amid this, something concerned people across, especially the health experts is the White House announcement of pulling the United States out of the World Health Organization (WHO) for a second time. Of the many, one of Trump's campaign promise was to reject global institutions, which is why the health experts are worrying that it could isolate the US with consequences for pandemic and disease response and diplomatic relations worldwide. US role in WHO?Historically, the US has been the largest founder of the WHO, a global health agency headquartered in Geneva, Switzerland, which is part of the United Nations. The WHO prepares for and fights off health emergency and in the World War II, the US has strongly influenced the agency. US, Joe, Trump, And WHOHowever, Trump had criticized WHO for the way COVID-19 pandemic was handled. When in 2020, pandemic reached its peak, he began the process to pull out from WHO. However, the former President Joe Biden, reversed this decision after taking office and restoring funding to WHO.ALSO READ: Who is Robert F. Kennedy Jr., the Controversial Nominee for U.S. Health Secretary?The order to pull out of the WHO once again came on the first day of his second term, which will allow him more time to actually implement this decision. The order said that the US was withdrawing "due to the organization’s mishandling of the COVID-19 pandemic that arose out of Wuhan, China, and other global health crises, its failure to adopt urgently needed reforms, and its inability to demonstrate independence from the inappropriate political influence of WHO member states." It also cited the "unfairly onerous payments" the U.S. has made to support the organization.Under the Biden administration, the US was the largest funder of the health agency, with a budget of $6.8 billion in the current fiscal year. This meant nearly a fifth of the WHO's budget came from the US. What do the health experts fear?Trump's decision has left the health experts in concern. Experts across public and private sectors, officials and academics have called this step disastrous and showed concerned about this decision which could eventually endanger the health of the nation and the world.Dr Ashish Jha, the Biden White House's former COVID-19 response coordinator called it a "catastrophic mistake" for the global community and a "terrible mistake" for the US.Another public health expert Lawrence Gostin, the faculty director of Georgetown University's O'Neill Institute for National and Global Health Law said, "This is going to be a grave strategic error that will make America less healthy and less safe." So, is this against the Trump's 'Make America Healthy Again' branding? This step could isolate the US in pandemic response.How will US withdraw from WHO?WHO's constitution which was drafted in New York did not have a clear exit method for member states. However, a joint resolution by Congress in 1948 outlined that the US can withdraw with one year's notice given that its financial obligations to WHO "shall be met in full for the organization's current fiscal year". The U.S. is the only member state to have made such an exit strategy. The former Soviet Union withdrew from WHO in 1949 during Cold War tensions, though returned years later.
