New Delhi: The slide in the number of fresh COVID-19 cases, deaths and positivity rate in Delhi can be attributed to aggressive containment measures, a segment of population achieving immunity and fewer outside patients, experts said on Friday (January 22). Some of them, however, noted that it is hard to “ascertain the actual position” as many people having mild symptoms have been skipping testing. Suresh Kumar, the medical director of Lok Nayak Jai Prakash Narayan Hospital, Delhi’s largest health facility, said authorities have been able to contain the coronavirus spread through aggressive testing and contact tracing. “More than one crore tests have been conducted in Delhi so far. On an average, around 60,000 to 70,000 tests are conducted daily. The Delhi government should be credited for its micro-management and planning,” he said.
The cumulative number of tests in Delhi crossed the one crore mark on January 20. Over 14 lakh tests have been conducted in the city between January 1 and January 21 — 66,683 tests a day on an average. However, Mr. Kumar said that whether Delhi has achieved herd immunity will be clear once the results of the latest serological survey arrive.
According to Dr. Ajit Jain, the nodal officer for COVID-19 at Rajiv Gandhi Super Specialty Hospital, Delhi may have achieved herd immunity already.
The serological-survey conducted in August found that 29.1 per cent of the city’s residents have developed antibodies against COVID-19. Besides, 35 per cent of the population is aged below 18 and is almost immune to the disease, he said.
Exposure to viruses causing common cold can also provide partial immunity against the coronavirus. This is called “cross-immunity”. Around five per cent of Delhi’s population is immune to COVID-19 due to this factor, Jain said. Another reason is that Delhi has become a “natural containment zone” due to the farmers’ agitation on its border points, he said. Earlier, a large number of COVID-19 patients from neighbouring states were coming to Delhi for treatment.
This number has reduced to a large extent due to the difficulty in travel due to the ongoing protest, Dr. Jain said. Around 30 per cent of the coronavirus patients admitted to Delhi hospitals in August last year were from other states, according to government data.
Non-residents also accounted for more than half the number of deaths reported in the national capital between August 3 and August 28 last year, it showed. Dr. Suneela Garg, director and professor in the department of community medicine at Maulana Azad Medical College, said a segment of Delhi’s population achieving immunity could be one of the reasons behind the declining trend in new COVID-19 cases and deaths.
Also, in many cases, people having mild symptoms do not come forward for testing. They go for isolation, she said.
Former director general of Indian Council of Medical Research (ICMR) N K Ganguly echoed similar views.
It is hard to ascertain the actual position as many people have not been turning up for testing if they have mild symptoms. They now know what precautions have to be taken, he said.
It is time the government asked experts to conduct “real-time” surveys to know the true picture. On an average, Delhi has recorded 348 cases a day in January so far. Authorities reported 399 cases on January 10; 306 on January 11; 386 on January 12; 357 on January 13; 340 on January 14; 295 on January 15; 299 on January 16; 246 on January 17; and 161 on January 18, the lowest since April 30 last year. The number of daily cases stood at 231 on Tuesday, 228 on Wednesday and 227 on Thursday.
The city registered 225 deaths between January 1 and January 21 — 10 fatalities a day on an average. The number of deaths was 12 on January 10; 13 on January 11; 16 on January 12; 11 on January 13; 4 on January 14; 10 on January 15; 6 on January 16; 8 each on January 17 and January 18;10 each on January 19 and 20 and 8 on January 21. The positivity rate has also come down from 1.29 on December 21 to 0.28 percent on January 21. Delhi Health Minister Satyendar Jain had said on Sunday, “The positivity rate has remained below 0.5 percent for the last few days. We can comfortably say that the third wave is on the wane.” “Cases have decreased. Still, I want to appeal to people to take precautions and use masks,” he had said.

NDTV – Dettol Banega Swasth India campaign is an extension of the five-year-old Banega Swachh India initiative helmed by Campaign Ambassador Amitabh Bachchan. It aims to spread awareness about critical health issues facing the country. In wake of the current COVID-19 pandemic, the need for WASH (Water, Sanitation and Hygiene) is reaffirmed as handwashing is one of the ways to prevent Coronavirus infection and other diseases. The campaign highlights the importance of nutrition and healthcare for women and children to prevent maternal and child mortality, fight malnutrition, stunting, wasting, anaemia and disease prevention through vaccines. Importance of programmes like Public Distribution System (PDS), Mid-day Meal Scheme, POSHAN Abhiyan and the role of Aganwadis and ASHA workers are also covered. Only a Swachh or clean India where toilets are used and open defecation free (ODF) status achieved as part of the Swachh Bharat Abhiyan launched by Prime Minister Narendra Modi in 2014, can eradicate diseases like diahorrea and become a Swasth or healthy India. The campaign will continue to cover issues like air pollution, waste management, plastic ban, manual scavenging and sanitation workers and menstrual hygiene.[corona_data_new]
