"We are concerned over these deaths and a team of experts will go there to assess the situation," a senior official in the Health Ministry said.
Most of the infants, who died in the government hospital in Purulia, were in the age group of 0-11 months. While eight deaths were reported on Friday, three died on Saturday and two on Sunday.
Sources said Rakesh Kumar, Joint Secretary in the Health Ministry has already spoken to the superintendent of the hospital seeking details of the incident.
The superintendent had said that the hospital is facing difficulties in treating such patients as the neo-natal unit has only ten beds, which needs to be increased as daily 15-20 infants in serious condition are referred to the hospital from the block-level hospitals.
