'Unauthorised' Bhagwat Katha programme cancelled in Greater Noida

New Delhi, Apr 24: The trajectory of COVID-19 cases could have plateaued and might even fall for some weeks after the lockdown is lifted but India is likely to see a second wave in late July or August with a surge in the number of cases during the monsoon, say scientists.

The timing of the peak will depend on how India is able to control physical distancing and on the level of infection spreads after restrictions are relaxed, they said.

It looks apparent that the trajectory of daily new cases has reached a plateau and eventually it will take a downward fall, maybe for some weeks or even months, Samit Bhattacharya, associate professor at the Department of Mathematics, Shiv Nadar University, said.

Still, we may get a surge of new cases of the same coronavirus and this will be considered a second wave, Bhattacharya explained.

The second epidemic may come back in late July or August in the monsoon, although the peak timing will depend on how we control social distancing during that time, he said.

Rajesh Sundaresan, professor at Bengaluru's Indian Institute of Science (IISc), agreed.

“Once we return to normal activity levels, there is a chance that infection may begin to rise again. China is seeing this to some extent post easing of some restrictions on travel,” Sundaresan, corresponding author of a working paper by researchers at IISc and the Tata Institute of Fundamental Research (TIFR) in Mumbai, said.

On March 25, when the number of coronavirus cases was 618 with 13 deaths, the government announced a nationwide lockdown that was later extended to May 3.

On Friday, the death toll due to COVID-19 rose to 718 and the number of cases to 23,077, according to the Union Health Ministry.

In good news, officials said this week that the doubling rate of cases has slowed down in the period, going from 3.4 days before lockdown to 7.5 days, with 18 states doing better than the national average. The recovery rate has also almost doubled in the last 10 days.

"Looking at the new cases in the past few days, it seems the growth of new daily infection is much slower than earlier. This apparently indicates that we might have reached at the plateau of the growth curve, Bhattacharya said.

He noted that recent studies in China and Europe observed that the infection might relapse in those people who have already recovered from earlier phases.

So, there is no evidence that the earlier infection may help acquire immunity against the second infection. And in that way, the entire population may be vulnerable to the second wave to some extent, said the scientist.

In their study unveiled this week, IISc and TIFR researchers analysed the impact of strategies such as case isolation, home quarantine, social distancing and various post-lockdown restrictions on COVID-19 that might remain in force for some time.

The study modelled on Bengaluru and Mumbai suggests the infection is likely to have a second wave and the public health threat will remain, unless steps are taken to aggressively trace, localise, isolate the cases, and prevent influx of new infections.

The new levels and the peaking times for healthcare demand depend on the levels of infection spreads in each city at the time of relaxation of restrictions, they said.

The lockdown is currently upon us. It has given us valuable time. Let us test, trace, quarantine, isolate, practice better hygiene, search for a vaccine, etc. We should do these anyway, and these are being done. When and how to lift the lockdown is going to be a difficult decision to make, said Sundaresan.

It's clear that it's going to be phased. What our team is focusing on is to come up with tools to help the decision makers assess the public health impact of various choices, he said.

According to the experts, infectious diseases spread via contact between infectious and susceptible people. In the absence of any control measures, an outbreak will grow as long as the average number of people infected by each infectious person is more than one.

Once enough people are immune there will be fewer people susceptible to the infection and the outbreak will die.

However, when an outbreak is brought under control by social distancing and other interventions, it is possible only a small proportion of the population will have been infected and gained immunity, they said.

This means enough susceptible people may remain to fuel a second wave if controls are relaxed and infection is reintroduced.

Until the vaccine comes on the market, we have to remain alert Once sporadic cases occur here and there in the country, we immediately need to implement quarantine or social distancing locally for the people in that region, and also need to perform tests to identify positive cases irrespective of showing symptoms, Bhattacharya explained.

Note that these monsoon months are also flu season in many places of India. So, we should not ignore the early signs of the flu symptoms. Irrespective of symptoms, we need to increase tests in the hotspots to identify people and contain the surge, he said.

Sundaresan added that the timeline for a second wave will depend on a lot of circumstances which may change as the time passes.

Significant testing may have been underway, there may be behavioural changes with people becoming more careful about their hygiene, wearing masks may become more common, etc. All these responses may help restrict the second wave, he said.

A study published in The Lancet journal earlier this month modelled the potential adverse consequences of premature relaxation of interventions, and found it might lead to a second wave of infections.

The finding is critical to governments globally, because it warns against premature relaxation of strict interventions, the researchers said.

While interventions to control the spread of SARS-CoV-2 are in place, countries will need to work toward returning to normalcy; thus, knowledge of the effect of each intervention is urgently required, they said in the study.

According to a recent analysis by the Harvard Chan School of Public Health, the best strategy to ease the critical care burden and loss of life from COVID-19 might be on-again, off-again social distancing.

In the absence of such interventions, surveillance and intermittent distancing may need to be maintained into 2022, which would present a substantial social and economic burden, the researchers wrote.p

New Delhi, Mar 24: Nearly 500 coronavirus cases have been reported in India so far, according to Health Ministry data on Tuesday.

Thirty-seven people have been cured/discharged/migrated, it added.

The number of active cases at 446 saw an increase of 22 from last night's figure.

As cases of the viral infection surged, authorities have put almost the entire country under lockdown, banning gathering of people and suspending road, rail and air traffic till March 31.

Kerala has reported the highest number of COVID-19 cases so far at 95, including eight foreign nationals, followed by Maharashtra which recorded 87, including three foreigners, according to the ministry data.

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.
