The three infants were in the age group of five months to two years in the inaccessible Rekhapalli and Kandhaguda villages under the Chitrakonda Police limits, treating physician R K Mohapatra said today.
While 13 children were admitted at the Chitrkonda Community Health Centre (CHC) in serious condition, others were being treated in the respective villages, Mohapatra said.
"A medical team with adequate medicines and disinfection materials has been sent to the villages to take a stock of the situation so that it does not break into an epidemic," he said.
