I asked colleagues about starvation in Gaza. They said there is no precedent for what is happening | Devi Sridhar

Famine looks inevitable without urgent intervention. Children are being starved of food - and it is entirely preventable

The news from Gaza feels too painful to watch. Videos of immediate violence capture TV and social-media audiences: within seconds, entire hospitals are destroyed and buildings fall to the ground. We are watching death in real time. In my last piece on Gaza, I highlighted the records being set: considering its short duration, it has been the deadliest war in modern history for children, for journalists, for healthcare workers and for UN staff. But there are parts of the on-the-ground situation that are harder to convey in short clips. The thing I hear most when I speak to colleagues in humanitarian organisations is that they are worried about starvation.

They say that, right now, Gaza has the highest proportion of people living with food deprivation anywhere in the world. Before 7 October, when the war started, acute malnutrition was largely nonexistent in Gaza. Since then, among children in northern Gaza it has increased to 15% - that's one in six children under the age of two - while it is 5% in Rafah in southern Gaza. Unicef has highlighted that 90% of children under five eat fewer than two food groups a day, which is defined as severe food poverty", while roughly 90% are affected by an infectious disease, including 70% with diarrhoea. A lack of nutrition and high rates of infectious disease cause a deadly cycle in children: hungry children are more likely to fall sick and have weak immune systems given their fragility, while diarrhoea causes weight and water loss in already thin children.
