In a significant move, President Trump has announced the withdrawal of the United States from the World Health Organization (WHO), a decision that has sparked a wave of concern among public health experts and international leaders. The WHO has expressed regret over the U.S. exit, highlighting the potential harm to global health initiatives, including those targeting HIV/AIDS in countries like Zimbabwe. Critics argue that this move could undermine global cooperation on health and potentially create an opening for other nations, such as China, to strengthen their influence. As the largest contributor to the WHO, the loss of U.S. support raises questions about the future funding and effectiveness of the organization. Experts warn that the U.S. decision may backfire, harming not only global health efforts but also American public health interests. Calls for Trump to reconsider the decision have emerged, with some asserting that reforming the WHO would be a more beneficial course than withdrawal.
