Dharmapuri, Nov 18 (ANI): Four more infants died at a government-run Dharmapuri Medical College Hospital in Tamil Nadu on Tuesday. Two were boys and two were girls. Of the four, one was delivered in the hospital while the other three were referred from other hospitals. All the four infants died due to being underweight because of pre-mature delivery and were suffering from respiratory problems. With the deaths on Tuesday, the toll mounted to nine after five crib deaths, which included four girls, were reported on Sunday. However, Dean of Medicine, Dharmapuri Government Hospital, Doctor Elangovan refused to take any responsibility of the deaths on behalf of the hospital. Of the five newborn babies who died on Sunday, three were underweight while the other two had respiratory problems. Reportedly, more than 20 babies are still in the hospital facing same problems and there is a fear that the death toll may increase.
