Three children died while undergoing treatment at the district headquarters hospital here, taking the toll to 61, Chief District Medical Officer Dr U S Mishra said.
Unconfirmed reports, however, put the toll due to the vector-borne disease at 65, which has affected around 100 villages spread over six of the seven blocks in the district.
At present, five affected children are being treated at the district headquarter hospital and two of them are in the ICU, a senior district official said.
The team members visited the district headquarters hospital here and held discussion with doctors and staff to assess the situation.
The disease, which originates from pigs and spreads to humans, mostly children, through mosquitoes, had surfaced in the district around 44 days ago.
A large number of pigs have been isolated and shifted to over 140 specially prepared enclosures set up away from human habitations, while fogging and spraying of mosquito repellents have been intensified in more than 100 villages, the official said.
