Four more cases of Covid-19 have been detected in Salt Lake over the past week and one of them, a 74-year-old cancer patient from Mizoram, has died.

The patients having tested positive recently are one each from Duttabad and Calcutta Armed Police (CAP) camp quarters, next to AE Block, and two from IB Block’s Mizoram House. This includes the patient who died.

The 74-year-old resident of Aizawl had come to Calcutta in March for treatment of cancer. He was admitted to a Salt Lake hospital on April 10 and discharged a few days later. But he was admitted once again on April 30. At around the same time, a 55-year-old man, also staying at Mizoram House, was admitted to the same hospital. Both tested positive for Covid-19 and the elderly man died on Sunday.

Police and civic officials have now turned IB Block into a containment zone. They have sealed off the lane from the Amul Island till Big Bazaar.

“We now have 84 guests at Mizoram House, out of whom around 19 have been sent to a government quarantine centre and the rest have been confined here itself,” said an official of Mizoram House. “We also have two houses in IB Block which are used to accommodate additional guests. The staff there have been cautioned too.”

Pranay Kumar Ray, the mayoral council member in charge of the health department of Bidhannagar Municipal Corporation, said they would ensure the delivery of food and essentials to Mizoram House. “We have requested police to ensure nobody steps out of the building and are in constant touch with the building authorities. We will provide them all possible help,” Ray said.

He also said they had sanitised all the lanes of IB Block.

More containment zones

The Covid-19 patient from Duttabad is a 32-year-old housekeeping staffer of a private hospital off EM Bypass. The man has been hospitalised and four of his family members are quarantined at a government unit. At CAP camp, a police constable has tested positive.

In all these areas, police has tightened security and is monitoring the movement of people. Including the cases of the previous weeks, the township now has more than a dozen sealed-off areas, a civic official said.

In the list of containment zones released on Tuesday night, FD, GC, HA, DB blocks, Mizoram House and Duttabad have been mentioned other than Basanti Debi Colony in Chingrihata.

In New Town, AL Block is the sole containment zone in Hidco-administered area. “A resident has tested positive there and has been admitted to MR Bangur Hospital. The family has been kept in isolation,” said a Hidco official. The list includes Gouranganagar Dhalai Bridge and Rekjoani in adjoining Rajarhat panchayat area as well as Chinar Park, Charnock Hospital, Haldiram and Samarpally, Kestopur among the Bidhannagar Municipal Corporation-administered areas nearby.
