The Calcutta Municipal Corporation has launched a search for setting up more quarantine centres as Calcuttans stuck in other states start arriving by train, civic officials said.

The civic body has readied a quarantine facility in New Town that Firhad Hakim, the chairman of the corporation’s board of administrators, inspected on Thursday. A building under construction in Anandapur is being converted into a quarantine centre.

The New Town facility — a campus of the Central Forensic Science Laboratory — can accommodate about 375 people, corporation sources said.

The centre at Anandapur, which is expected to be ready in 10 days, would be able to accommodate 400 people.

A building of ESI Hospital under construction at Baltikuri in Howrah, about 12km from Esplanade, will also be used to quarantine contacts of Covid-19 patients.It can accommodate around 300 people.

Chief minister Mamata Banerjee tweeted on Thursday that 105 trains will be bringing back people from Bengal stuck in other states till June 14. A list of the trains she tweeted says 25 of them will arrive at Howrah station.

“Many of the people may need to be quarantined. Some of them could be migrant workers who will not have enough space at home to remain quarantined. So we will need more quarantine beds in the city,” a civic official said.

A health team of the corporation is screening all those arriving from other states for Covid-19 symptoms at Netaji Indoor Stadium and advising quarantine as necessary.

Hakim has also asked civic officials to ensure that no symptomatic person or contact of a positive patient living in a slum be kept in home quarantine.

“Several people stay crammed together in a room in slums. They do not have space at home to stay isolated from other family members for 14 days. Therefore, such people should be shifted to the government created quarantine facilities soon,” said the CMC official.
