Investigate everyone, be it Vadra or PM: Rahul Gandhi

New Delhi, May 10: A medium-intensity earthquake of 3.4 magnitude hit Delhi on Sunday.

According to the National Center for Seismology (NCS), the quake occurred at 1.45pm at a depth of five kilometres.

There were no immediate reports of loss of life or property.

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 19: The number of coronavirus cases crossed the one lakh mark in the country on Tuesday, while the death toll due to the infection touched 3,163, according to the Union Health Ministry.

A total of 134 deaths and 4,970 COVID-19 cases were reported in the country in the past 24 hours since 8 pm on Monday, it said.

The total number of coronavirus cases has risen to 1,01,139, the ministry said.

The number of active COVID-19 cases stood at 58,802 while 39,173 people have recovered and one patient has migrated, it said.

"Thus, around 38.73 per cent patients have recovered so far," a senior health ministry official said.

The total confirmed cases include foreigners.

Of the 134 deaths reported since Monday morning, 51 were in Maharashtra, 35 in Gujarat, 14 in Uttar Pradesh, eight in Delhi, seven in Rajasthan, six in West Bengal, four in Madhya Pradesh, three in Tamil Nadu, two each in Punjab and Jammu and Kashmir, and one each in Bihar and Telangana.

Jharkhand, Chandigarh and Himachal Pradesh each have recorded three COVID-19 fatalities, while Assam has reported two deaths.

 Meghalaya, Uttarakhand and Puducherry have reported one fatality each, according to the data provided by the ministry.

According to the ministry's website, more than 70 per cent of the deaths are due to comorbidities, the existence of multiple disorders in the same person.

According to the health ministry's data updated in the morning, the highest number of confirmed cases in the country are from Maharashtra at 35,058, followed by Tamil Nadu at 11,760, Gujarat at 11,745, Delhi at 10,054, Rajasthan at 5,507, Madhya Pradesh at 5,236 and Uttar Pradesh at 4,605.

The number of COVID-19 cases has gone up to 2,825 in West Bengal, 2,474 in Andhra Pradesh and 1,980 in Punjab.

It has risen to 1,597 in Telangana, 1,391 in Bihar, 1,289 in Jammu and Kashmir, 1,246 in Karnataka and 928 in Haryana.

Odisha has reported 876 coronavirus infection cases so far, while Kerala has 630 cases. A total of 223 people have been infected with the virus in Jharkhand and 196 in Chandigarh.

Tripura has reported 167 cases, Assam has 107, Uttarakhand and Chhattisgarh have 93 cases each, Himachal Pradesh has 90 and Ladakh has registered 43 cases so far.

"814 cases are being reassigned to states," the ministry said on its website, adding "our figures are being reconciled with the ICMR".

State-wise distribution is subject to further verification and reconciliation, it said.
