Several households in Salt Lake are refusing to undergo Covid tests despite multiple families members displaying symptoms.

“Our department is conducting door-to-door surveys, through which we are identifying houses where multiple residents are displaying symptoms,” said an an official of Bidhannagar Municipal Corporation’s health department. “But when we send over teams of health workers, these families are refusing to get themselves tested. We cannot force them. This is a worrying trend.”

Although the number of fresh Covid cases in the corporation area is now hovering around 15-20 a day, multiple members of the same family are testing positive, said the official.

Meanwhile at least four new micro-containment zones have been earmarked in different wards of the corporation by the district administration on Monday.

The four are in different blocks of Salt Lake, the official said.

Of the new buildings identified as micro-containment zone, one is in BC Block, another in AC Block and a third in FC Block. A first floor apartment of the Meghnad Saha Abasan in AF Block has also been identified as a micro-containment zone.

The total number of containment zones in the planned area of Salt Lake is now 12. Last week it was 11 but some houses in the older list are now off the radar.

The civic body still has the highest number of containment zones as compared to the district’s municipalities.
