GENEVA: Global health funding faces historic challenges as donor countries reduce their contributions, the director of the World Health Organization said on Thursday.

The US withdrew from the WHO in January, saying the health agency had mishandled the COVID-19 pandemic and other international health crises. 

The US is the UN health agency’s most prominent financial backer, contributing around 18 percent of its overall funding.

“We are living through the greatest disruption to global health financing in memory,” Tedros Adhanom Ghebreyesus said at WHO headquarters in Geneva.

The WHO revised its budget after the American withdrawal exacerbated a funding crisis due to member states reducing their development spending.

Faced with an income gap of nearly $600 million this year, the WHO has proposed slashing its budget for 2026-27 by 21 percent from $5.3 billion to $4.2 billion, and reducing staff numbers, according to an internal memo seen by Reuters.

“It is of course, very painful,” the director added, warning that the cuts would significantly impact the health of people around the world.

Separately, the executive director of the WHO’s emergencies programs said the minds and bodies of children in Gaza were being broken following two months of aid blockade and renewed strikes. 

“We are breaking the bodies and minds of the children of Gaza. We are starving the children of Gaza. We are complicit,” Deputy Director General Michael Ryan said at the WHO’s headquarters.

“As a physician, I am angry. It is an abomination,” he said.

“The current level of malnutrition is causing a collapse in immunity,” Ryan said, warning that cases of pneumonia and meningitis in women and children could increase.

The UN warned this week that acute malnutrition among Gaza’s children was worsening.
