No apology or withdrawal of charges against Devyani Khobragade: US

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 29: The total number of COVID-19 positive cases rose to 1024 in the country, said Ministry of Health and Family Welfare on Sunday.

"The total number of COVID-19 positive cases rise to 1024 in India including 901 active cases, 96 cured/discharged/migrated people and 27 deaths," Ministry of Health and Family Welfare said.
Prime Minister Narendra Modi had on Tuesday announced a 21-day lockdown to stem the spread of COVID-19, which has left thousands dead around the world.

New Delhi, Jul 22: Rajya Sabha Chairman M Venkaiah Naidu on Wednesday urged the newly elected members of the House to uphold rules and procedures of the House while discharging their duties as the lawmakers for the country.

"In his remarks at the end of the administration of oath/affirmation to the new members of Rajya Sabha in the Chamber of the House today, Shri Naidu urged them to hold themselves to account with regard to their conduct both within and outside the House, so as to enhance the standing of the institution in the eyes of the people," read a press note.

The note further read that Naidu suggested the members to "question themselves if they had acted to enhance the dignity of the institution or to the contrary at the end of each day during the session and if their conduct was ethical during the inter-session period".

He said, "Answers to these simple questions would guide you on the right path."

He further stressed, "Ensuring rule of law is the spirit of our law of the land (Constitution). It shall begin with your compliance with the rules and procedures of this House."

Of the 61 members elected to Rajya Sabha from 20 States in the recent biennial and bye-polls, 45 made oath/affirmation today including 36 who have been elected for the first time. 12 sitting members have been re-elected which include Sharad Pawar, Digvijaya Singh, Bhubaneswar Kalita, Prem Chand Gupta, Harivansh and Ramdas Athawale, who took oath today.

Those elected for the first time to Rajya Sabha include Mallikarjun Kharge, Jyotiraditya M Scindia and KC Venugopal who have vast legislative experience and taken oath today. Those members who could not make oath/affirmation will do so during the ensuing Monsoon Session.

"Members including three women made oath/affirmation in 10 languages viz., Telugu, Bodo, Kannada, Manipuri, Marathi, Oriya, Tamil, Bengali, Hindi and English," the note read further.

"Today's oath-taking has been organized to enable the newly elected members to participate in the committee meetings which are underway at once and in the monsoon session which is to follow. I hope to nominate all of you on different committees in a day or two. #RajyaSabha," the Vice President's official handle tweeted earlier on Wednesday.
