The World Health Organisation warned on Friday of surging respiratory illnesses in Gaza, with worse expected after heavy ​rains flooded tens of thousands of tents housing displaced Palestinians.

"The numbers already show the pressure. Acute respiratory infections are 33,000 cases higher than at the same time last year,” Dr Reinhilde Van De Weerdt, WHO representative in the Occupied Palestinian Territory, told reporters ⁠in Geneva from Jerusalem.

Poor living conditions and severe overcrowding are driving up infections.

"It is shocking that just a few days of rain really showed us what the coming months will bring. And winter has not even fully set in. The worst really is yet to come," Van De Weerdt said.

Nearly ​a million displaced people in Gaza live in flood-exposed ‌areas, ⁠and 400,000 of them ‌are in locations that are considered at extremely high risk, ‌according to the WHO.

The agency said flooding heightened the risk of contaminated water, while standing water gave mosquitoes and pests more places to breed. Dampness encouraged mould ⁠and bacteria that are major drivers of respiratory infections, especially in young children, it said.
