The World Health Organization (WHO) is tightening its budget as the United States, its biggest financial backer, prepares to step away by January 2026. The US currently chips in about 18% of the WHO’s funding, making its departure a significant blow to the global health agency.

In a memo sent to staff on January 23, WHO Director-General Tedros Adhanom Ghebreyesus outlined the cost-cutting steps. The organization is freezing new hires, slashing travel budgets, shifting meetings to virtual formats, delaying IT upgrades, and putting office renovations on hold. Tedros emphasized that these measures are just the beginning, with more adjustments expected soon.

The WHO’s budget relies heavily on dues and voluntary contributions from member countries. The US withdrawal, which has drawn sharp criticism from health experts worldwide, threatens to leave a leadership vacuum in global health. Kenneth Bernard, a former biodefense official, didn’t hold back in his assessment, calling the move “just stupid” and warning that it could allow China to step into the void.

With the US set to pull out, the WHO faces a challenging road ahead. The agency is determined to protect its staff and maintain its mission, but the financial strain is undeniable. As the world watches, the question remains: who will fill the gap left by the US?
