Sensationalism killed the telecom sector: Kapil Sibal

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.

New Delhi, Jun 9: A record rise in COVID-19 cases in India for the seventh consecutive day has pushed the tally to over 2.6 lakh on Tuesday, with the daily nationwide spike in coronavirus cases inching close to 10,000.

The rise in cases comes at a time when the country has stepped out of a 75-day coronavirus lockdown with malls, religious places and offices opening in several parts of the country under strict conditions.

Since the onset of June, the country has also been witnessing over 200 COVID-19 fatalities each day that has taken the country's death toll to 7,466.

India is the fifth worst-hit nation by the COVID-19 pandemic after the US, Brazil, Russia and the UK, according to the Johns Hopkins University data.

Several states like Haryana, Jammu and Kashmir, Assam, Haryana, Karnataka, Chhattisgarh and Tripura among others have been showing a spurt in cases.

A total 266 new COVID-19 fatalities and 9,987 cases have been reported in the last 24 hours till Tuesday 8 am, according to the Union Health Ministry data.

The country has registered over 9,000 coronavirus infection cases for the sixth day in a row taking the country tally to 2,66,598.

The number of active novel coronavirus cases stands at 1,29,917, while 1,29,214 people have recovered and one patient has migrated, according to the Health Ministry data updated till 8 am.

"Thus, 48.47 per cent patients have recovered so far," a ministry official said.

According to the ICMR, a total of 49,16,116 samples have been tested as on 9 am, Tuesday, with 1,41,682 samples been tested in the last 24 hours.

State-wise distribution is subject to further verification and reconciliation, it said.

Jun 23: The U.S. government on Monday restricted charter flights from India, accusing the nation of "unfair and discriminatory practices" by violating a treaty governing aviation between the two countries.

Air India Ltd. has been making flights to repatriate its citizens during the travel disruptions caused by the Covid-19 outbreak, but also has been selling tickets to the public, the Transportation Department alleged.

At the same time, U.S. airlines have been prohibited from flying to India by aviation regulators there, the DOT said in its order. The situation "creates a competitive disadvantage for U.S. carriers," the agency said in a press release.

Air India is advertising a schedule that is more than half of pre-virus operations, the department said. "The charters go beyond true repatriations, and it appears that Air India may be using repatriation charters as a way of circumventing" that nation's flight restrictions, the U.S. agency said.

The order becomes effective in 30 days, the department said.

Indian airlines must apply to the DOT for authorization before conducting charter flights so that it can scrutinize them more closely, it said. The department will reconsider the restrictions once India lifts restrictions on U.S. carriers.

The action against India follows weeks of DOT restrictions against Chinese airlines after the U.S. agency accused that nation of unfairly banning American carriers in the wake of the virus. On June 15, the U.S. announced it would agree to allow four flights a week from China after it allowed the same number by U.S. carriers.

Attempts to reach Air India and the Indian embassy in Washington after business hours were unsuccessful.
