In all, it said at least 45% of Gaza's housing units had reportedly been damaged or destroyed.
It was impossible to independently verify the numbers, but Reuters reporters in Gaza say the destruction is on a huge scale.
OCHA said 55 ambulances in Gaza had been damaged, with critical shortages reported of drugs and blood products.
The socio-economic situation of Gaza was already dire before the war, with the poverty rate estimated to have reached 61% in 2020.
They also forecast that the war would cost Gaza between 4% and 12% of gross domestic product in 2023.
