"Three children from the children's home were hospitalised on Wednesday and Thursday and one of them, Baney (14), died late on Wednesday.
"They had symptoms of diarrhoea," Dr SD Sharma, superintendent of J L Lone hospital said today.
Ruling out possibility of food poisoning, he said the condition of two boys was stable.
The home for differently-abled children is run by the department of social justice and empowerment.
Officials of the department were not available for comments.
