Voting ends, counting begins amid boycott in violence-hit Bangladesh

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.

May 29: A total of 367 domestic flights, carrying 30,136 passengers, operated throughout the country till 5 pm on Thursday, Civil Aviation Minister Hardeep Singh Puri said.

Airports in West Bengal also started operations on Thursday, three days after domestic air travel resumed in India after a gap of two months.

All scheduled domestic passenger services were suspended in India from March 25 to May 24 due to restrictions in the wake of the coronavirus pandemic.

Earlier in the day, Puri had said that 460 domestic flights carrying 34,336 passengers were operated on Wednesday.

In the case of West Bengal, the minister on Sunday had said that the state will handle domestic flights from Thursday.

"Figures for domestic flights for 28th May 2020 are in. Departures 367, 30,136 passengers handled. Arrivals 310, 25,530 passengers handled. Total movements 677 with 55,666 passenger footfalls at airports.

 “Total number of flyers 30,136. These are numbers till 1700 hrs for Day 4," Puri said in a tweet.

A total of 428 domestic flights carrying 30,550 passengers and 445 domestic services carrying 62,641 flyers were operated in the country on Monday and Tuesday, respectively.

In February this year, when the lockdown was not imposed, around 4.12 lakh passengers travelled daily through domestic flights in India, according to Directorate General of Civil Aviation (DGCA) data.

During the pre-lockdown period, Indian airports handled around 3,000 daily domestic flights, aviation industry sources said. A total of 16 asymptomatic passengers on seven different flights including 13 of them who travelled by IndiGo have tested positive for COVID-19 since the resumption of domestic air services on Monday, according to airlines data.

Two of the three asymptomatic passengers who tested positive for the infection had travelled by Spicejet while one took a flight of Air India subsidiary Alliance Air.

The Karnataka government, meanwhile, said on Thursday it has requested the civil aviation ministry to reduce the number of flights originating from five states--Maharashtra, Gujarat, Tamil Nadu, Madhya Pradesh and Rajasthan--in the light of the high number of COVID-19 cases there, hours after a minister said it has "suspended" air travel from these states.

Seeking to clarify his statement, Law and Parliamentary Affairs Minister J C Madhuswamy maintained that Karnataka has not sought imposing a ban on flights from the five states as reported in some sections of the media. "India is flying high. Domestic operation figures for May 27, 2020 (till 23.59 hrs): Departures 460 with 34,336 passengers handled. Arrivals 464 with 33,525 passengers handled," Puri had said earlier in the day on Twitter.

If a flight takes off before midnight and lands in another airport after midnight, its departure and arrival are counted on different days, leading to a seeming mismatch in the figures of a particular day.

The Delhi airport, India's busiest airport, is scheduled to handle 147 departures and 145 arrivals on Thursday, said senior government officials. The Mumbai airport's operator MIAL said it handled a total of 50 domestic flights on Thursday. International passenger flights continue to remain suspended in the country.

Airports in West Bengal, Andhra Pradesh, Maharashtra, Telangana and Tamil Nadu have been allowed to handle a restricted number of daily flights as these states do not want a huge influx of flyers amid the rising number of COVID-19 cases.

While domestic services resumed in Andhra Pradesh on Tuesday, they restarted in West Bengal on Thursday.

Though domestic flight operations across the country began on May 25, they could not be restarted in Kolkata and Bagdogra as the state's machinery was involved in relief and restoration work after cyclone Amphan's devastation.

"Welcome Back, Passengers! Kolkata Airport saw the arrival of 122 passengers from @DelhiAirport after two long months and 40 passengers departed to Guwahati. Proper checks were followed, and regular sanitization was carried out in the terminal which was abuzz with passengers," the Kolkata airport tweeted.

On Thursday, eleven flights took off from Kolkata and an equal number arrived in the city, sources at the Netaji Subhas Chandra Bose International Airport said.

"A total of 1,745 passengers arrived and 1,214 passengers flew out of the city today (Thursday)," airport sources said.

The airports in Kolkata and Bagdogra are permitted to handle 20 daily flights each from Thursday onwards.

While it is not clear how many flights were handled by the Bagdogra airport on Thursday, the officials said 899 passengers arrived while 484 passengers departed from the airport during the day.

The West Bengal government recently came up with a set of guidelines for people arriving in the state on domestic flights.

According to it, those entering the state from Thursday must submit a self-declaration form, stating that they have not tested positive for COVID-19 in the past two months.

The passengers will also need to undergo health screening after they arrive at the airport, the state's guidelines said.
