GENEVA: A “public health catastrophe” is imminent in Gaza, the World Health Organization (WHO) said on Tuesday, amid overcrowding, mass displacement and damage to infrastructure.

WHO spokesperson Christian Lindmeier warned of the risk of civilian deaths not directly linked to Israeli bombardment.

“It’s an imminent public health catastrophe that looms with the mass displacement, the overcrowding, the damage to water and sanitation infrastructure,” Lindmeier told reporters.

Gaza health authorities say more than 8,300 Palestinians have been killed since Israel began air strikes on the Hamas-run enclave in response to the Oct. 7 attacks when Hamas killed 1,400 people in Israel and took more than 200 hostages.

The Israeli military began ground operations in Gaza last week.

Asked if people were dying from complications other than those from the bombardment, Lindmeier said: “Indeed they are.” A spokesperson from the UN Children’s Fund (UNICEF), James Elder, warned of the risk of infant deaths due to dehydration, with water output at 5% of normal levels.

“So child deaths due to dehydration, particularly infant deaths due to dehydration, are a growing threat,” he said, adding that children were getting sick from drinking salty water.

About 940 children are reported missing in Gaza, he said, with some thought to be stuck beneath the rubble.

Others are suffering from trauma or severe stress, he said, such as the 4-year-old daughter of a UNICEF colleague who has begun harming herself by ripping out her hair and scratching her thighs until they bleed.

The UN humanitarian office in a statement earlier on Tuesday said water supplies to southern Gaza came to a halt on Monday “for unknown reasons.” Lindmeier called for fuel to be allowed into Gaza to allow a desalination plant to operate.

Israel has blockaded the Gaza Strip and refuses to allow in fuel supplies, saying it could be used by Hamas for military purposes.
