President Javier Milei's decision echoes that of his ally, U.S. President Donald Trump, who began the process of pulling the United States out of WHO with an executive order on his first day back in office on Jan.

Argentina will pull out of the World Health Organization (WHO), the presidential spokesperson Manuel Adorni said on Wednesday, following President Donald Trump's executive order last month to pull the United States out of the global health group.

The World Health Organization (WHO) is a specialised agency of the United Nations responsible for global public health. It is headquartered in Geneva, Switzerland, and has six regional offices. The WHO's purpose is to achieve the highest possible level of health for all people across the world.
