Shambhulal Regar, who lynched Muslim man, all set to contest 2019 polls

New Delhi, April 5: People were seen buying diyas and candles across the country to light them at 9 p.m. on Sunday to fight the "darkness of coronavirus" as requested by Prime Minister Narendra Modi.

Although the country is under a lockdown and all the shops barring those selling essential items are shut, but a number of makeshift roadside shops and carts have cropped up selling earthen lamps or diyas at various places.

The earthen lamps, along with other 'puja samgari', are also sold near various temples. Those shops also opened on Sunday.

Gatherings at the temples and other religious places too are barred.
Those who did not find diyas in their localities contended with candles available at the local general stores.

Prime Minister Narendra Modi had on April 3 appealed to people in a televised address to light diyas and candles on April 5 at 9 pm to fight the darkness spread by coronavirus pandemic.

"Friends, amidst the darkness spread by the corona pandemic, we must continuously progress towards light and hope. We must defeat the deep darkness of the crisis by spreading the glory of light in all four directions," said the Prime Minister in a video message.

"And that is why, this Sunday, on April 5, we must all together, challenge the darkness spread by the corona crisis, introducing it to the power of light. On this day, we must awaken the superpower of 130 crore Indians. We must take the super resolve of 130 crore Indians to even greater heights," Modi said.

He asked the people to turn off all the lights in their homes and stand at doors or balconies and light candles or diyas, torches or mobile flashlights for 9 minutes on April 5.

"In that light, in that lustre, in that radiance, let us resolve in our minds that we are not alone, that no one is alone! 130 crore Indians are committed, through a common resolve!" he said.
PM Modi's call to light diyas, torches or mobile flashlights amid the lockdown has proved to be a boon for shopkeepers selling diyas and candles.

"Sales of diyas have increased to 50 per cent and we also got orders. It has happened because of Modi ji's appeal. We are with him in this," Ram Ravi Kumar, a shopkeeper in Delhi told news agency.

Vikas Kumar, a resident of Patna, said, "I have bought 50 diyas for today. PM Modi had said that people have to light the diyas for nine minutes after switching off light at home."
Modi has asked citizens to not assemble anywhere while participating in this programme and emphasised on the importance of social distancing to prevent coronavirus spread.

Meanwhile, the number of positive cases of coronavirus in the country continues to surge. As per the Ministry of Health and Family Welfare, the total number of confirmed COVID-19 cases is 3,374 with 79 deaths.

Lucknow, May 3:Holding the Tablighi Jamaat responsible for the spread of COVID-19, Uttar Pradesh Chief Minister Yogi Adityanath on Saturday said that being infected with a virus is not a crime but to hide it is definitely a crime.

Speaking at a programme of a news channel, Adityanath said, "The role of Tablighi Jamaat was most condemnable. To get a disease is not a crime but to hide a disease which is infectious is definitely a crime. And this crime has been done by those associated with the Tablighi Jamaat."

"In Uttar Pradesh and other places where the spread of the coronavirus has been seen, Tablighi Jamaat is behind it. Had they not hidden the disease and went about like its carriers, then perhaps we would have controlled the coronavirus outbreak to a large extend," he said.

The chief minister said action would be taken against them for the "crime that they have committed".

A Tablighi Jamaat congregation in Delhi in March turned out to be a major source of COVID-19 cases, with those who attended the meet returned home in different parts of the country after being infected with the deadly virus.

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
