Lucas Kiwomya, seven, a pupil at Highfields School in Lawford, Essex, was taken to Colchester General Hospital on Wednesday after suffering breathing difficulties. He died shortly after arrival.
A spokesman for Highfields School said: "We are all devastated at Highfields by the sudden and untimely death of a much respected and well-loved pupil.
