Too many leaks, the 'chowkidar' is weak: Rahul Gandhi

New Delhi, Apr 17: A total of 3,336 Indians tested positive for coronavirus in 53 countries while 25 others died of the infection, government sources said on Thursday.

They said the Indians stranded abroad will have to be patient as the government is not evacuating them as part of a larger policy decision to check the spread of the coronavirus in the country.

"They need to be patient and stay where they are. Our missions have been told to extend all possible help to the stranded Indians," said a source.

According to the sources, evacuation of around 35,000 foreign nationals from 48 countries has been facilitated so far from India.

The sources said the majority of Indians who tested positive for the coronavirus infection are living in the Gulf region. A sizeable number of Indians staying in France and the US have also tested positive.

They said that Indian missions in the Gulf region have been told to extend all possible assistance to the Indians in distress.

Around eight million Indians are living in the Gulf countries and there has been growing anxiety among them over their livelihood in view of the pandemic as it has majorly impacted the oil-driven economy of the region.

Almost all Gulf countries have taken a series of drastic measures including imposing total lockdown, travel restrictions and even closing borders to stem the spread of the coronavirus infection.

The United Arab Emirates has already warned of possible action against countries refusing to allow their citizens to return.

Around 3.3 million Indians are living in the UAE and they constitute roughly 30 per cent of the country's population. Among the Indian states, Kerala is the most represented followed by Tamil Nadu and Andhra Pradesh.

A large number of Indians are working in the construction sector in Qatar which is hosting the FIFA World Cup in 2022.

As a matter of policy, India has decided not to bring back the stranded Indians from abroad till the nationwide lockdown ends.

The issue of Indians in Gulf region figured prominently during Prime Minister Narendra Modi's video conference with heads of Indian missions abroad on March 30.

Welfare of Indians in the Gulf was the major focus area in the discussions Modi had with leaders of countries in the region over the last few weeks, officials said.

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.

Domestic flights resumed operations on a truncated schedule on Monday with the first aircraft departing from the Delhi Airport for Pune, more than two months after a nationwide lockdown was announced to combat COVID-19.

The first flight to take off was an IndiGo aircraft to Pune, flying passengers stranded in the national capital since the lockdown was announced on March 24.

Passengers were screened at the airport with electronic thermometers, and revised protocol for air travel that included santisation of luggage through ultra-violent scanners, and maintaining physical distancing.

Only asymptomatic passengers were allowed to enter the airport.

Passengers were also seen wearing face masks and face shields given to them at the embarkation point by the airline to minimise the chances of infection while onboard.

The first flight arrived at Delhi Airport from Ahmedabad – a SpiceJet aircraft – at around 8:00 am.

BJD Lok Sabha member Anubhav Mohanty was among those who took the Air Vistara flight to Bhubaneshwar that departed Delhi airport at 6:50 am.

The first flight to take off from Mumbai was an IndiGo aircraft that departed for Patna at 6:45 am, while passengers from Lucknow were the first to reach the financial capital on an IndiGo aircraft that touched down at 8:20 am.

The food & beverage and retail outlets, which were closed for the past 63 days, opened at Terminal 3 of Delhi’s Indira Gandhi International (IGI) Airport.

The flight services resumed after a day of long and hard negotiations between the Centre and the states on Sunday.

All states finally agreed to accept at least some flights but announced different quarantine and self-isolation rules for arriving passengers to address apprehension about infections being brought in from other cities.

The Centre had issued guidelines for all modes of domestic travel that advised all asymptomatic passengers to self-monitor their health parameters for 14 days on completion of the journey and report to health authorities if they displayed any symptoms for COVID-19.

However, the Centre had allowed state governments to prescribe their own health protocols for disembarking passengers which led to differential guidelines across the country.
