India will become 'Hindu Rashtra' by 2024, says BJP leader

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, May 11: With an increase of 4,213 cases in the past 24 hours, India's COVID-19 count reached 67,152 on Monday, according to the Union Ministry of Health and Family Welfare.

The number of active cases in the country rose to 44,029, while 20,916 patients have been cured and discharged and one has migrated, according to the Ministry.

The number of deaths in the country due to the infection reached 2,206 on Sunday.

Maharashtra, with 22,171 confirmed cases is the worst-affected due to the infection so far and is followed by Gujarat with 8,194 cases.

However, Tamil Nadu surpassed the national capital in total coronavirus cases numbers. Delhi has 6,923 reported cases while Tamil Nadu has 7,204 confirmed cases.

Maximum deaths due to coronavirus have so far been recorded in Maharashtra (832), followed by Gujarat which has toll of 493.

New Delhi, Jun 18: Republican Party of India (RPI-A) leader Ramdas Athawale on Thursday urged Indians to boycott Chinese food and asked for a ban on all restaurants which serve the cuisine.

"Restaurants selling Chinese food should be banned. Restaurants should be closed by the order of the state government. I appeal to people who consume Chinese food to boycott it," Athawale told ANI here.

The Union Minister also said that both the products which come from China and its literature should also be banned in the country.

"The Chinese literature should also be banned, its products too should be banned and its companies too should not be given business here. We should develop such companies in the country which can manufacture the same products here," he added.

Athawale also warned China to reconsider its actions and stop its nefarious activities on the border by saying, "You took Buddha from us but we don't want yuddha (war) with you. A war will prove to be costly for both countries, economically and loss of lives will also occur. If we (Indians) are not crossing the border then why are you doing so?"

Athawale's statements came after at least 20 Indian Army personnel, including a Colonel rank officer, lost their lives in the violent face-off in the Galwan valley area of Ladakh on June 15.

The clash happened as a result of an attempt by the Chinese troops to "unilaterally change" the status quo during de-escalation in eastern Ladakh and the situation could have been avoided if the agreement at the higher level been scrupulously followed by the Chinese side, India said on June 16.
