Authorities have locked down several neighbourhoods in Dhaka's Mirpur and Basabo areas as two-thirds of the people who tested positive for Covid-19 on Sunday are from those localities.
Security has been ramped up in the affected areas, with at least 11 confirmed cases in Mirpur and seven including six family members in Basabo.
Responding to a query, Mirpur Division Deputy Commissioner of Police Mostak Ahmed said, "Security has been beefed up, and so far 40 buildings in Uttar Tolarbagh and a few buildings in Shah Ali Bagh, Kalawalapara, Kafrul, Mirpur 11 and Mirpur 13 have been locked down."
Police have placed a neighbourhood in Dhaka's Mirpur 1 under lockdown on Sunday as an elderly couple tested positive for the novel coronavirus, said Mirpur police station Officer-in-Charge Mostafijur Rahman.
"The couple lived on the second floor of a building in Shah Ali Bagh, and they have been taken to the Kuwait-Bangladesh Friendship Hospital," said the police officer.
Police personnel have been deployed in the area, and they are asking residents through the public address system to stay alert and remain indoors.
Another elderly person at Uttar Tolarbagh was tested positive for the virus the same day, said an official of the Institute of Epidemiology, Disease Control and Research (IEDCR).
"The patient was a regular mosque-goer and was suffering from respiratory problems recently. His samples were taken on Friday and was tested positive," said the official.
Meanwhile, at least seven people from the Dakshingaon area, including six from A SINGLE family, tested positive for the coronavirus in the last few days, said Shabujbagh Police Station Inspector (operation) Shah Alam.
"Police have put the Dakshingaon under lockdown after multiple people from the area tested positive for the coronavirus, and the patients were sent to the Kuwait-Bangladesh Friendship Hospital," said the inspector.
The elderly person, who works as a security guard, was infected at first. Then his wife, two daughters and two grand-daughters also tested positive for the virus. The remaining patient is a grocer, said police sources.
