NEW DELHI: The intensive door-to-door screening at Nizamuddin Basti and the surrounding areas, aimed at checking if any community transmission of the novel coronavirus infection has taken place in the wake of the Tablighi Jamaat incident in the area, was completed by health officials on Monday amid heavy security.A doctor who was part of the drive said preliminarily six individuals had shown cold-cough flu-like symptoms and had been asked to strictly home-quarantine themselves. “We will keep a track and see if they develop any Covid-19-like symptom, including dry cough and fever, in the coming days. If necessary, we will shift them to hospital,” he added.During the three-day exercise, 13 teams of doctors, nurses, NGO volunteers and security personnel checked more than 1,900 houses, covering over 7,000 people. Dozens of CRPF jawans and civil defence personnel were deputed to make sure that the teams do not face any harassment as some residents objected to the drive on the first two days. Some of them were apprehensive that this was a National Population Registry-like survey, said a civic official.Health officials are worried about “non-cooperative houses” where people refused to divulge any detail. Till Sunday, the survey teams came across 64 such houses. “Following the resistance faced on the first day, we were told not to argue at any such house and simply note down their addresses. A separate list of such houses has been prepared and will be submitted to the disease surveillance officer for further action,” said an official of the South Delhi Municipal Corporation. A few houses were also found locked.A member of the joint survey team said they were sent to collect information such as the name of the head of the family, details about people showing any flu-like symptoms like cough and fever, number of people in a family, their travel history and contact details, including phone numbers.To contain any further spread of the infection in relation to the Tablighi Jamaat headquarters, which has become a super spreader following a religious gathering, SDMC has also finished screening all 95 public health, field and sanitation workers involved in checking congregation participants and disinfecting the area.
