I skipped rally because I was misled: Anna Hazare

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, Feb 4: Miffed over the controversy created by its former Union minister and Uttara Kannada MP Anantkumar Hegde by his remarks against Mahatma Gandhi, the BJP, it was learnt, has issued a show-cause notice to him. The ruling party came under heavy criticism from the opposition over its MP’s remarks. The opposition has demanded a clarification from Prime Minister Narendra Modi over his party MP’s remarks.

Often in news for his controversial remarks, Hegde, sources said, could also be barred from attending the first parliamentary party meeting of the BJP of the budget session, scheduled on Tuesday. The party had taken a similar approach against its Bhopal MP Pragya Thakur during the last winter session for praising Mahatma Gandhi’s killer Nathuram Godse. Though the BJP leadership was earlier of the view that Hegde should tender an apology over his remarks but the party top brass, it was learnt, decided that it was not enough.

The Congress on Monday launched a scathing attack on the central government over the comments of BJP Lok Sabha MP Ananthkumar Hegde on Mahatma Gandhi. The party demanded that Prime Minister Narendra Modi come to Parliament and clarify his position on BJP leader’s “objectionable” remarks.

Congress party spokesman Anand Sharma said, “we can understand that why one after the other senior BJP leaders are insulting the memory of Mahatma Gandhi. They are disparaging the national movement, the freedom struggle because they are ideological descendents of those who were not only non-participants, but, actively opposed the freedom movement.” He further added, “Parliament is in session. We demand that the Prime Minister come to the House and make his position clear. As I have said, feeds that he is unhappy and angry, we are not concerned with that. In the very ideology, mindset, thinking and language of the BJP, there is violence.”

Asserting that the BJP MP’s statement was condemnable, Rajasthan Chief Minister Ashok Gehlot said the leaders of the saffron party could afford to call the freedom movement a drama as they never fought for the country’s independence. “Such statements reveal their true mindset that they use Gandhi's name just for show and have no regard for him,” he said.

New Delhi, Jun 24: In a stinging attack on the Gandhi family of the Congress, BJP president J P Nadda on Wednesday said a dynasty and its courtiers have "grand delusions" of the opposition being about itself and stated that a "rejected and ejected" family is not equal to the entire opposition.

In his tweets, Nadda said it was the time for unity and solidarity, and the "relaunch of the scion for the nth time can wait", an apparent dig at Rahul Gandhi, who has been aggressive in his attacks on Prime Minister Narendra Modi for his handling of the border row with China.

Nadda said India lost thousands of square kilometres of land due to the "misadventures of one dynasty" and claimed that the Siachen glacier, where the Indian Army has a strong presence, was almost gone. No wonder India has rejected them, he said.'

The BJP president posted a news report to back his assertions about Siachen.

"One 'royal' dynasty and their 'loyal' courtiers have grand delusions of the Opposition being about one dynasty. A dynast throws tantrums and his courtiers peddle that fake narrative. The latest one relates to the Opposition asking questions to the Government," Nadda said.

Though he did not directly name the Gandhi family or any of its members, the reference was clear.

He said it was the opposition's right to ask questions and added that the all-party meeting called by Prime Minister Narendra Modi saw healthy deliberations, with several opposition leaders giving their valuable inputs.

They also fully supported the Centre in determining the way ahead, Nadda said.

"One family was an exception. Any guesses who," he asked.

Targeting the Gandhis, the BJP president said, "One rejected and ejected dynasty is NOT equal to the entire Opposition. One dynasty's interests are not India's interests. Today, the nation is united and supportive of our armed forces. This is the time for unity and solidarity. Relaunch of 'the scion' for the nth time can wait."
