A day after six people who attended a religious gathering near Nizamuddin Dargah tested positive for the coronavirus disease (Covid-19), authorities are on the lookout for others who took part in the event.

Over the past two days, the Delhi Police and the health department have taken at least 220 people to two separate quarantine facilities at Tughlaqabad and Lok Nayak Hospital, a police official who did not want to be named said.

The gathering inside a mosque had many foreign nationals too, a second official said.

People from Andaman and Nicobar Islands, Telangana and Tamil Nadu attended the gathering, a Delhi health department official said, adding that the six who tested positive are believed to have travelled from Andaman. They had no history of foreign travel.

“They were living with a group of people for some religious gathering,” a health department official said on the condition of anonymity. “Now activities are going on to trace others who might have come in contact with them,” this official said.

Earlier this month, the Delhi government banned religious, social, cultural and political gatherings of over 50 people till March 31 in view of the coronavirus outbreak.

Later, nationwide restrictions were imposed on the movement of people for 21 days March 25 to prevent the spread of the coronavirus.

Later, Prime Minister Narendra Modi announced a 21-day nationwide lockdown that came into effect from March 25 to prevent the spread of the coronavirus.

“The whole city is under lockdown. Now with some cases of people showing symptoms of Covid-19 reported from Nizamuddin area, we have posted more police personnel at the market places and the lanes to ensure that people follow the lockdown. Our officers on the ground are also helping the government officers in Nizamuddin basti area,” deputy commissioner of police (south east) RP Meena said.

The Nizamuddin basti area has a high population density.

Twenty-three people tested positive for Covid-19 in Delhi on Sunday, taking the total number of cases to 72, according to the health officials from the city. This is the largest jump in numbers in a single day in the national capital.

So far, two deaths have been reported from Delhi – that of a 68-year-old woman from Janakpuri and a 62-year-old Yemeni man who was in Delhi for his son’s liver transplant.
