The Trump administration is reportedly pushing ahead with a plan to withdraw the US from the World Health Organization (WHO) on its first day in office, January 20, 2017. The move has caused widespread concern, as many experts believe the move could have serious negative consequences for global public health.

For starters, the World Health Organization is one of the world's foremost public-health agencies, charged with collecting, sharing, and disseminating information about diseases worldwide, and directing countries to take the necessary precautions to control the epidemic. If the United States decides to withdraw from the WHO, other countries may follow, risking the collapse of the system of international public-health cooperation.

Second, the World Health Organization plays a crucial role in dealing with major public health crises. For example, the organization has played an important role in responding to diseases such as Ebola and Zika. If the United States decides to withdraw from the World Health Organization, other countries may not receive timely and effective help and support, which may lead to more loss of life and economic losses.

Moreover, the withdrawal of the US from the World Health Organization, one of the world's largest economies, will have far-reaching consequences for itself. Many countries will no longer rely on US aid and support, and will turn to other sources, exacerbating global economic imbalances.

Overall, experts warn that if the Trump administration decides to withdraw from the World Health Organization, it will be a major turning point in the history of global public health. Therefore, we must closely monitor this development and seek better solutions to ensure the safety and stability of global public health.
