Around 900 people are still under observation in Pathanamthitta after the district administration released a route map identifying places visited by the three-member family from Ranni which returned to Kerala from coronavirus-hit Italy last month, health officials said.
Around 16 squads led by the District Collector and the District Medical Officer (DMO) travelled across the the district to identify the places visited by the family and to track the contacts, a senior medical official of the state said.
"A flow chart was prepared with all the places visited by the family upon their return and have been mentioned in a map, so that people can voluntarily inform authorities if they had come in contact with them," state Health Minister K.K Shailaja said.
The Minister told the Assembly on Friday that the patient flow chart was released as the family was not revealing everything to the medical department.
The Pathanamthitta DMO told the authorities received hundreds of calls from various places in the district after the travel map of the family was released.
"Those who were at the place and time mentioned in the flow chart were asked to contact the health authorities. We have identified around 70 people on the first day itself. Next day, i.e on Thursday, we identified around 40 people who came in close contact with the Ranni family," the DMO said.
