22 April 2025 — At a crowded health post in northern Ethiopia, Belaynesh Berihu cradles tiny daughter Eldana, as a health worker slips a coloured tape around the infant’s arm to gauge malnourishment.

“She eats very little, she doesn’t have an appetite,” says Berihu, whose daughter weighed less than 2 kg at birth. Berihu, too, is painfully thin – surviving on a diet of mostly wheat and teff-based bread.
