People from Jammu being brought for PM's Srinagar rally: Omar

New Delhi, Jun 4: India's Defence Secretary Ajay Kumar tested positive for COVID-19 on Wednesday, following which the defence ministry carried out a massive contact-tracing exercise, official sources said.

Kumar's condition is stable and he is currently under home-quarantine, they said.

At least 35 officials working at the ministry's headquarters in South Block in the Raisina Hills have been sent on home quarantine after reports of Kumar testing positive for the infection emerged on Wednesday morning.

There was no official comment on Kumar's health condition. The defence ministry spokesperson refused to comment on the issue.

It is learnt that Defence Minister Rajnath Singh did not attend office as part of a precautionary measure.

The offices of the defence minister, the defence secretary, the Army Chief and the Navy Chief are on the first floor of the South Block.

The sources said all laid down protocols on contact-tracing and quarantining of people are being scrupulously followed.

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, Jun 18: The border clash between Indian and Chinese soldiers in Ladakh broke the brittle quiet – and also the sense of security for anxious Chinese nationals in India who fear a backlash with anti-Chinese sentiment spiralling in the country.

With the high altitude violent face-off in eastern Ladakh’s Galwan Valley spurring hashtags such as “Boycott China” and “Teach Lesson to China” and leading to street protests, the undercurrents of tension were evident.

Wary of being identified, some said they had been reassured by their friends but were still apprehensive for themselves and their families.

"They (Chinese families) don''t want to speak to the media. They are not going out and are worried about their security and well being. Their families are also worried back home," Mohammed Saqib, secretary general of the India China Economic & Cultural Council, told PTI.

He added that his Chinese friends in India been calling him since they heard news about Monday night’s clashes in which 20 Indian soldiers were killed -- the worst military confrontation in five decades -- and expressed concern over growing anti-China sentiments.

A Chinese national from Beijing working in Gurgaon for a Chinese mobile firm initially refused to talk, saying he did not want to speak to the media and later shared his thoughts only on condition of anonymity.

"There is talk of border standoff and tensions, but we know Indians are very warm people and that is why I have told my family that all is fine here and they should not worry," he said.

Another Chinese national working in Gurgaon said he and his family are feeling the stress amid the spiralling conflict between India and China, but many friends have been reassuring him.

"They (Chinese in India) are under a lot of stress naturally. Such a conflict puts a lot of stress as they could bear the brunt and the same applies to Indians in China," B R Deepak, professor at the Centre for Chinese and South East Asian Studies of the Jawaharlal Nehru University said.

He said it was unfortunate that the border standoff derailed the commemorative programmes aimed at strengthening ties at a time the two countries were gearing to celebrate 70 years of establishment of diplomatic ties.

Experts also feel the border clash is likely to have a significant negative impact on the economic and people to people ties.

There are scores of Chinese in India working in various Chinese firms and also those who are studying in universities like JNU.

About 3,000 Chinese people, doing business or studying in big cities in India, were stranded in India at the start of the COVID-19 crisis, and about half of them returned to China before the lockdown began on March 25.

The Chinese Embassy in New Delhi announced on May 25 that they will arrange for flights to take back students, tourists and businesspersons to five Chinese cities, including Shanghai and Guangzhou.

"It will impact the psychology of the Chinese here. There are 2,000 Chinese firms in various sectors in India which are going to be impacted," Deepak said.

Future investments from the Chinese side could also be impacted, he said.

Moreover, as far as people-to-people contacts are concerned, the number of Chinese students choosing India as a preferred destination is likely to go down, Deepak said.

Alka Acharya, another China expert, said there are two kinds of impacts of such an incident -- short term and medium term.

Usually after the initial nationalistic reaction in the short term things tend to normalise in the medium term, but with such a border clash happening for the first time in decades clearly the resonance would be much more in both India and China, said Acharya, professor at the Centre for East Asian Studies, School of International Studies, in JNU.

“Due to the impact of the COVID-19 crisis on the economy, whether India can take a hardline in terms of economics towards China, is a tricky question,” she said.

In the immediate context, there may be a dip in economic ties with calls for boycott of Chinese goods and services, Acharya said.

The manner in which this crisis is resolved will affect how ties will be affected in the medium term, she said.

The headlines have added to the anxiety.

A group of ex-armymen gathered near the Chinese embassy to protest the killing of 20 Indian Army personnel in Ladakh’s Galwan Valley. And another group of around 10 protesters belonging to the Swadeshi Jagaran Manch protested near the Teen Murti roundabout in Central Delhi.

The anti-China sentiment prevalent among the common public is also finding a reflection in government policy with sources saying the Department of Telecom (DoT) is set to ask state-owned Bharat Sanchar Nigam Ltd (BSNL) not to use Chinese telecom gear in its 4G upgradation.

Trade bodies like CAIT are also calling for a boycott of Chinese products.

And Chinese handset maker Oppo cancelled the livestream launch of its flagship 5G smartphone in the country amid protests.

Monday night’s clashes between the Chinese and Indian troops in Galwan Valley significantly escalated the already volatile border standoff between the two countries.

The casualties on the Chinese side are not yet known. However, government sources, citing an American intelligence report, claimed the total number of soldiers killed and seriously wounded could be 35.
