Two minor sisters have died of an undiagnosed disease at a hospital in Jammu & Kashmir’s Reasi district, officials said on Saturday. The news of the deaths put the district administration on alert, prompting the authorities to constitute a special medical team to ascertain the cause. The deceased were identified as Ashruti Devi, 8, and Asho Devi, 5. They passed away on Friday at Reasi District Hospital within two hours of being brought there by their father Prem Chand from far-flung Danour village in Arnas area, officials said. The bodies were handed over to Mr. Chand for last rites after the post-mortem on Saturday.Hospital Superintendent Pritam Singh said it was premature to say anything about the disease. Mr. Chand said the girls fell sick a few days ago and at that time the family believed it was a case of throat infection. Reasi District Development Commissioner Sagar Dattatray Doifode said, “The special medical team visited Danour village on Saturday and conducted an inspection among the people for symptoms of diphtheria, but nothing of the sort was found,” he said.The medical team was carrying out a preventive vaccination drive in the village and adjoining areas.
