President, Sonia express concern over lynching incidents

New Delhi, May 23: The nationwide lockdown will no longer help India in its fight against COVID-19, and in its place community-driven containment, isolation and quarantine strategies have to be brought into play, leading virologist Shahid Jameel said.

The recipient of Shanti Swarup Bhatnagar Prize for Science and Technology also stressed that testing should be carried out vigorously to identify coronavirus hotspots and isolate those areas.

"Our current testing rate at 1,744 tests per million population is one of the lowest in the world. We should deploy both antibody tests and confirmatory PCR tests. This will tell us about pockets of ongoing infection and past (recovered) infection. This will provide data to open up gradually and let economic activity resume," Jameel told PTI in an interview.

He stressed that testing has to be dynamic to continuously monitor red, orange and green zones and change these based on that data.

About community transmission of COVID-19 in India, Jameel said the country reached that stage long ago.

"We reached community transmission a long time ago. It's just that the health authorities are not admitting it. Even ICMR's own study of SARI (severe acute respiratory illness) showed that about 40 per cent of those who tested positive for SARS-CoV-2 did not have any history of overseas travel or contact to a known case. If this is not community transmission, then what is?" he posed.

Lockdown bought India time in its fight against coronavirus, but continuing it is unlikely to yield any further dividend, Jameel said.

"Instead, community-driven local lockdowns, isolations and quarantines have to come into play. Building trust is most important so that people follow rules. A public health problem cannot be dealt with as a law-and-order problem."

The nationwide lockdown, initially imposed from March 25 to April 14, has been extended thrice and will continue at least till May 31. The virus has claimed 3,720 lives and infected over 1.25 lakh people in the country so far.

Jameel has expertise in the fields of molecular biology, infectious diseases, and biotechnology. He is the CEO of Wellcome Trust/Department of Biotechnology's India Alliance and is best known for extensive research in Hepatitis E virus and HIV.

He said COVID-19 will eventually be controlled through herd immunity, which is acquired in two ways – when a sufficient fraction of the population gets infected and recovers, and with vaccination.

"It is estimated that for SARS-CoV-2 at least 60 per cent of the population would have to be infected and recovered, or vaccinated. This will happen over the course of the next few years," Jameel said.

Herd immunity is reached when the majority of a population becomes immune to an infectious disease, either because they have become infected and recovered, or through vaccination. When that happens, the disease is less likely to spread to people who aren't immune, because there just aren't enough infectious carriers.

"India has 1.38 billion people, a population density of about 400/sq km and a healthcare system ranked at 143 in the world. If we allow 60 per cent people to get infected quickly in the hopes of herd immunity, that would mean 830 million infections," Jameel said.

"If 15 per cent need hospitalization that means about 125 million isolation beds (we have 0.3 million). If five per cent need oxygen and ventilatory support, this amounts to about 42 million oxygen support and ICU beds; we have 0.1 million oxygen support beds and 34,000 ICU beds. This would overwhelm the healthcare system causing mayhem," he said.

Jameel said if the population level mortality is 0.5 per cent that would mean 40 lakh deaths. "Are we prepared to pay this price for herd immunity in the short term? Clearly not," he said.

He said it is unlikely that a vaccine would be available by the end of the year.

"Even then, we don't know yet how long it would give protection – weeks, months, one year, a few years? I don't think we will return to pre-coronavirus days for at least the next 3-5 years. This is also a chance to evaluate if we want to return to those unsustainable, environment-damaging ways. COVID-19 is a timely warning to reform our way of living," he said.

Jameel said it is hard to predict but plausible that COVID-19 would return in second or third wave.

"Later waves come when we don't understand the disease and become lax. A comparison to Spanish Flu is not entirely valid because in 1918 no one knew what caused it. No one had seen a virus till the mid-1930s as the electron microscope needed to view those was invented in 1931," he said.

"Today we know a lot more about the pathogen, its genetic makeup, how it transmits and how to prevent it. We need to be sensible and follow expert advice," he said.

If there is any scientific evidence linking deforestation, rapid urbanisation, climate change with pandemics like COVID-19, he said zoonotic viruses -- those that jump from animals to humans -- happen so when wild animal–human contacts increase.

"Deforestation destroys animal habitats bringing them closer to humans. When you cut forests, bats come to roost on trees closer to human habitations. Their viruses in secretions/stool get transmitted to domestic animals and on to humans. This happened clearly with Nipah virus outbreak in Malaysia in 1997-98 from fruit bats to pigs to humans," he said.

"COVID-19 possibly arose in wet animal markets due to dietary habits that bring all kinds of live and dead wild animals in close contact with humans," Jameel added.

May 29: Over 45,000 stranded Indians were brought back home from abroad under the Vande Bharat mission and another 1,00,000 will be evacuated till June 13, the Ministry of External Affairs said on Thursday.

The mega evacuation mission was launched on May 7.

MEA Spokesperson Anurag Srivastava said the government is also assisting return of stranded Indians from remote locations in Latin America and Caribbean, Africa, and parts of Europe.

"This is being done by taking advantage of foreign carriers flying to India primarily for evacuation of their nationals," he said during an online media briefing.

He said a total of 45,216 Indians were brought back till Thursday afternoon and they include 8,069 migrant workers, 7,656 students and 5,107 professionals.

About 5,000 Indians have returned through land border from Nepal and Bangladesh.

In the first phase of the mission from May 7 to 15, the government evacuated around 15,000 people from 12 countries. The second phase of the evacuation mission was scheduled from May 17 to 22. However, the government has extended it till June 13.

Srivastava said a total of 3,08,200 people have registered their request with Indian missions abroad for repatriation to India on compelling grounds.

"During the phase two, a total of 429 Air India flights (311 international flights + 118 feeder flights) from 60 countries are scheduled to land in India. The Indian Navy will be making four more sorties to bring back returnees from Iran, Sri Lanka and the Maldives," Srivastava said.

The MEA spokesperson said the government is targeting to bring back 1,00,000 people from 60 countries by the end of phase two of the Vande Bharat mission.

"Preparations for third phase of Vande Bharat Mission are well underway," he said.

As per the government's policy for evacuation, Indians having "compelling reasons" to return like pregnant women, elderly people, students and those facing the prospect of deportation are being brought back home.

New Delhi, Mar 31: At least 24 people staying at Markaz building in Nizamuddin area of the national capital have tested positive for coronavirus, Delhi Health Minister Satyendar Jain on Tuesday.

"All of them are being screened. We are not certain of the number but it is estimated that 1500-1700 people had assembled at the Markaz building. 1033 people have been evacuated so far - 334 of them have been sent to the hospital and 700 sent to quarantine centre. Total 24 positive cases have been found so far," he said while speaking to reporters here.

The minister also slammed the organisers of the religious event saying that they have committed a grave crime.

"The event's organisers committed a grave crime. Disaster Act and Contagious Diseases Act was enforced in Delhi, no assembly of more than 5 people was allowed. Still, they did this. I have written to Lieutenant Governor to take strict action against them. Delhi government has given an order to file an FIR against the organisers," the Health Minister said.

Earlier, the Delhi government had said: "It has come to our knowledge that administrators of Nizammuddin Markaz violated coronavirus lockdown conditions and now several positive cases have been found. Strong action would be taken against those in charge of this establishment. Delhi government will ask the police to register an FIR against Maulana of Markaz, Nizamuddin."
