System cleaning done by BJP govt after 2014 unbelievable, says Nirmala Sitharaman

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, Mar 24: Thirty-two states and Union Territories (UTs) have announced complete lockdown to check the spread of the coronavirus in the country, informed the Central government on Tuesday.
There is a complete lockdown in as many as 560 districts of the country affecting several hundred million people.
Earlier, the complete lockdown was imposed in 30 districts, as of now, almost the entire country is in lockdown to restrict public movement in an attempt to break the chain of transmission of coronavirus.
Three states -- Uttar Pradesh, Madhya Pradesh and Odisha -- have announced lockdown in select districts with the governments continuously monitoring the situation and ready to extend the restrictions to other districts as well.
The Union Territory of Lakshadweep has announced restrictions on certain activities.
The Indian Railways has suspended all passenger train operations till March 31 in view of coronavirus.

Thiruvananthapuram, Jan 25: Kerala Chief Minister Pinarayi Vijayan on Friday asked the state's MPs to take up the matter of deaths of eight Keralites at a resort in Nepal early this week, with the Centre to pursue the matter with the neighbouring country's government.

He was speaking to the MPs at the customary meeting that the Chief Minister has with all MPs ahead of every session of the parliament.

"The demand has come from the families of the victims for a fair probe on what happened and adequate compensation. For this, you (MPs) should take it up with the Centre. A probe has to be done by the Nepal authorities and the Centre should pursue this with them," Pinarayi reportedly stated. 

"We (the state government) have already taken the issue with the Centre and will now send a detailed letter on the need for a fair probe by the Nepal authorities," he added.

The eight dead include Praveen Krishnan Nair, who worked in the UAE and was on a short vacation here, when the tragedy struck the family. His wife Saranya, a second year M.Pharma student, and their three children, were also killed.

On Friday morning, it was a goodbye that Thiruvananthapuram has perhaps not seen before, as hundreds of people, many of them strangers, came to pay last respects to the five members of the Nair family.

The family of Praveen Nair decided to bury the bodies of the three children and cremate the bodies of Praveen and Saranya. It was also decided to bury the ashes of the couple alongside their three children in the compound of their house.

The second family hailed from Kozhikode and the bodies of Ranjith, an IT professional, his wife, who works in a cooperative bank and their younger child, who slept in the same room as that of Praveen, arrived at the Kozhikode airport on Friday morning.

State Transport Minister A.K. Saseendran and many others were there to receive the bodies, which were first taken to Ranjith's new home that is almost complete.

From there it was taken to a hall for all to pay their last respects and then to the family home of Ranjith where the cremation took place.

Watching everything happening was Ranjith's elder son, seven-year-old Madhav, who escaped that night in Nepal as he was sleeping in another room.

Madhav had arrived from Delhi on Thursday and was unaware of the tragedy as he was busy moving around in a new bicycle, which his relatives had bought to keep him busy.
