President, Vice President greet people on eve of Eid-ul-Zuha

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.

Apr 11: India has sent back 20,473 foreigners who wanted to return to their countries following the Covid-19 global pandemic, it was revealed on Friday (April 10).

"So far, we have successfully evacuated 20,473 foreign nationals as of yesterday. This is an ongoing process," said Dammu Ravi, Coordinator on Covid-19 issues at the Ministry of External Affairs, MEA.

"This involves several countries," Ravi said during the daily government briefing on Covid-19, although he could not list the countries offhand. "We are receiving excellent cooperation from governments all over the world for this process."

Many foreigners, especially tourists, were stranded in India when domestic and international flights were abruptly cancelled last month in a bid to curb transmission of the coronavirus.

The Ministry of Tourism has asked stranded foreigners to get in touch with the government through a special portal started for the purpose, through their embassies in India and other sources to facilitate their evacuation if they wished to head home.

As of Friday evening, the Ministry of Health and Family Welfare had confirmed 6,761 Covid-19 cases in India, of whom 515 patients have been cured.

There were 206 deaths reported from across the country.

Two states, Punjab and Orissa, have extended the ongoing lockdown until April 30.

Prime Minister Narendra Modi will consult state chief ministers on Saturday to decide whether to extend the country-wide lockdown, which is due to end at midnight on April 14.

New Delhi, May 13: Finance Minister Nirmala Sitharaman on Wednesday announced Rs 3 lakh crore collateral-free automatic loan for businesses, including MSMEs.

This will benefit 45 lakh small businesses, she said detailing parts of the Rs 20 lakh crore economic stimulus package.

The loan will have 4-year tenure and will have a 12-month moratorium, she said.

Also, Rs 20,000 crore subordinated debt will be provided for stressed MSMEs, she said adding this would benefit 2 lakh such businesses.

The Finance Minister said a fund of funds for MSME is being created, which will infuse Rs 50,000 crore equity in MSMEs with growth potentials.

Also, MSME definition has been changed to allow units with investment up to Rs 1 crore to be called micro-units in place of Rs 25 lakh now.

Also units with turnover up to Rs 5 crore to be called micro-units, she said, adding a turnover based criteria is being introduced to define small businesses.

The investment and turnover limits for small and medium businesses have likewise been raised to allow them to retain fiscal and other benefits, she said.

Global tenders will be banned for government procurement up to Rs 200 crore, she said, adding this would help MSMEs to compete and supply in government tenders.
