State apathy delays infra projects

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.

Mumbai, Apr 2: NCP chief Sharad Pawar on Thursday

urged Muslims to observe Shab-e-Barat staying inside their homes, and also suggested that the birth anniversary celebrations of Dalit icon Dr B R Ambedkar be postponed in view of the coronavirus outbreak.

Pawar said Ram Navami, being observed on Thursday, is celebrated with fervour every year across the country.

"Unfortunately, there is this threat of coronavirus this year and we have to observe some restrictions...but I am sure people must be remembering Lord Ram staying inside their homes," he said in his address via Facebook.

Shab-e-Barat, also known as the night of forgiveness,will be observed on April 8.

Members of the Muslim community visit graveyards to remember their relatives who are no more, Pawar said, and called for taking precautions to avoid gathering of people given the coronavirus crisis.

Pawar said congregation such as the one held last month in Delhi's Nizamuddin area by Tablighi Jamaat could have been avoided, and urged people to ensure there is no repeat of such meetings on Shab-e-Barat.

"The meeting should have been avoided, but it was notand others may have to pay for it," Pawar said referring to the religious meeting in the national capital.

He said the "possibility of some people who attended the meeting carrying the disease cannot be ruled out" and pressed for maintaining discipline given the situation caused by the COVID-19 outbreak.

"Shab-e-Barat is on April 8. Muslims remember their relatives, who are not more, by visiting kabrastan (graveyard). It should be observed inside home. Precaution should be taken to see there is no repeat of the Nizamuddin meeting-like episode," he said.

The birth anniversary of Ambedkar, the architect of the Indian Constitution, is observed on April 14.

Pawar said people should also think about postponing Ambedkar's birth anniversary celebrations.

"We normally celebrate it (the anniversary) for two or so months. We should think whether we should really observe the programme at this juncture (given the coronavirus threat).

If we come together, we may have to face health issues," the former Union minister said.

He said in general, 90 per cent people have been observing the lockdown, but 10 per cent are not doing so.

The Centre and the Maharashtra government may have to extend the lockdown period if discipline is not observed till April 14 (till when the lockdown is in force), he said, urging people to toe the line in the interest of each other.

Pawar also praised Chief Minister Uddhav Thackeray, the state administration and police for working round-the- clock, and asked people to cooperate with them by staying at home.

Visakhapatnam, Jun 13: A four-month-old baby who was on ventilator treatment for 18 days for COVID-19 was on Friday evening discharged from hospital after testing negative.

"A tribal woman of East Godavari named Laxmi was infected with COVID-19 in May, later the doctors confirmed that her four-month-old baby was also infected," said District Collector, Vinay Chand.

"The baby was shifted to Visakhapatnam VIMS hospital on May 25. She was treated for 18 days on a ventilator. Doctors again conducted baby's COVID-19 test recently, following which the reports came negative. After a health check-up, VIMS doctors discharged the baby on Friday evening," he added.

Meanwhile, 14 new COVID-19 positive cases have been reported in Visakhapatnam district on Friday, taking the total number of cases to 252 including one fatality due to the virus.
