Now, PM Modi likens army's surgical strike to Israel's exploits

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, Apr 23: The nationwide lockdown in India which started about a month ago has impacted nearly 40 million internal migrants, the World Bank has said.

The lockdown in India has impacted the livelihoods of a large proportion of the country's nearly 40 million internal migrants. Around 50,000 60,000 moved from urban centers to rural areas of origin in the span of a few days, the bank said in a report released on Wednesday.

According to the report -- 'COVID-19 Crisis Through a Migration Lens' -- the magnitude of internal migration is about two-and-a-half times that of international migration.

Lockdowns, loss of employment, and social distancing prompted a chaotic and painful process of mass return for internal migrants in India and many countries in Latin America, it said.

Thus, the COVID-19 containment measures might have contributed to spreading the epidemic, the report said.

Governments need to address the challenges facing internal migrants by including them in health services and cash transfer and other social programmes, and protecting them from discrimination, it said.

World Bank said that coronavirus crisis has affected both international and internal migration in the South Asia region.

As the early phases of the crisis unfolded, many international migrants, especially from the Gulf countries, returned to countries such as India, Pakistan, and Bangladesh until travel restrictions halted these flows.

Some migrants had to be evacuated by governments, such as those of China and Iran, it said.

Before the coronavirus crisis, migrant outflows from the region were robust, the report said.

The number of recorded, primarily low-skilled emigrants from India and Pakistan rose in 2019 relative to the prior year but is expected to decline in 2020 due to the pandemic and oil price declines impacting the Gulf countries.

In India, the number of low-skilled emigrants seeking mandatory clearance for emigration rose slightly by eight percent to 368,048 in 2019.

In Pakistan, the number of emigrants jumped 63 per cent to 6,25,203 in 2019, largely due to a doubling of emigration to Saudi Arabia, it said.

According to the bank, migration flows are likely to fall, but the stock of international migrants may not decrease immediately, since migrants cannot return to their countries due to travel bans and disruption to transportation services.

In 2019, there were around 272 million international migrants.

The rate of voluntary return migration is likely to fall, except in the case of a few cross-border migration corridors in the South (such as Venezuela-Colombia, Nepal-India, Zimbabwe South Africa, Myanmar-Thailand), it said.

Migrant workers tend to be vulnerable to the loss of employment and wages during an economic crisis in their host country, more so than native-born workers.

Lockdowns in labour camps and dormitories can also increase the risk of contagion among migrant workers.

Many migrants have been stranded due to the suspension of transport services. Some host countries have granted visa extensions and temporary amnesty to migrant workers, and some have suspended the involuntary return of migrants, it said.

Observing that government policy responses to the COVID-19 crisis have largely excluded migrants and their families back home, the World Bank said there is a strong case for including migrants in the near-term health strategies of all countries, given the externalities associated with the health status of an entire population in the face of a highly contagious pandemic.

The Bank said governments would do well to consider short, medium and long-term interventions to support stranded migrants, remittance infrastructure, loss of subsistence income for families back home, and access to health, housing, education, and jobs for migrant workers in host/transit countries and their families back home.

The pandemic has also highlighted the global shortage of health professionals and an urgent need for global cooperation and long-term investments in medical training, it said.

New Delhi, Jan 1: Newly-appointed Chief of the Defence Staff General Bipin Rawat on Wednesday said the armed forces stay away from politics and work as per the directives of the government of the day, remarks that come amid allegations that the forces were being politicised.

Gen Rawat also said that his focus as CDS will be to integrate the efforts of the three services and to work as a team.

"We keep ourselves away from politics. We act according to the directives of the government of the day," he said.

Gen Rawat said his focus will be to ensure best and optimal use of resources allocated to the three services.
