Public health experts and global leaders have warned that the United States’ withdrawal from the World Health Organization (WHO) could weaken global disease surveillance and make both America and the wider world less safe.
The warning follows the formal announcement by the US government to disengage from the global health body, a move that has sparked concern across diplomatic and medical communities. WHO plays a central role in coordinating responses to pandemics, disease outbreaks, vaccination campaigns, and health emergencies.
Experts argue that withdrawing from the organization limits access to critical data-sharing platforms that track emerging diseases worldwide. Without active participation, the US risks delayed access to early warning systems designed to detect outbreaks before they become global threats.
Health analysts note that infectious diseases do not respect borders, making international cooperation essential. They say reduced US involvement could slow coordinated responses to future pandemics similar to COVID-19, Ebola, or emerging influenza strains.
The WHO also supports low- and middle-income countries with technical expertise, vaccines, and medical infrastructure. Observers fear that diminished US funding could weaken these efforts, potentially allowing preventable diseases to spread and mutate.
American public health professionals have also expressed concern that the withdrawal could undermine US influence in shaping global health policies and standards. They warn that stepping back creates a vacuum that other global powers may fill.
Despite the criticism, US officials argue that the decision is driven by concerns over efficiency, accountability, and national interest. However, critics insist that reform is best pursued through engagement rather than withdrawal.
Global health advocates continue to urge a reconsideration of the move, warning that reduced collaboration increases risks not only for vulnerable populations abroad but also for Americans at home.
