With Kerala Chief Minister Pinarayi Vijayan asking the State Police to locate all those who have visited the Tablighi Jamaat in Nizamuddin in Delhi, around 300 of them have been identified from various parts of the state.
But of the 300 who took part in the prayer sessions, only 80 are deemed to have returned to Kerala.
While over 200 took part in the first week, an estimated 80 are understood to have been there in the third week.
While there has been some reluctance on the part of those who have taken part to cooperate, the police are doing their best to find out by tracking the mobile numbers of such people.
Meanwhile around a dozen people who have been identified appear to be fine and have no symptoms of coronavirus, but the health authorities are leaving nothing to chance and have put them into isolation.
