Nearly 500 coronavirus cases in India; 9 deaths

Thiruvananthapuram, Apr 24: The month of Ramzan will be observed from Friday in Kerala.
The crescent moon was seen at Kappad beach in Kozhikode on Thursday.

Amid nationwide lockdown in the wake of COVID-19, there will be no group prayers at mosques. The devotees have been directed to offer prayers at homes.

Palayam Mosque Imam, VP Suhaib said, "Usually at mosques in Thiruvananthapuram, devotees used to come to break the fast... But this year, amid lockdown, we direct people to prepare food at home and break the fast with family. Also, there will not be group prayers at mosques. People should pray at home."
"Imams and scholars have strictly directed people to observe all Ramzan-related prayers at home. There is no other option... Human life is the most important thing. Only if life exists, belief and religion can exist," he added.

Prime Minister Narendra Modi had on March 24 announced a 21-day nationwide lockdown as a precautionary measure to contain the spread of COVID-19. Later, the lockdown was extended till May 3.

Mumbai, Mar 29: Virologist Minal Dakhave Bhosale led from the front to create India's first coronavirus testing kit even when she was in the last stage of her pregnancy.

Bhosale's efforts paid the price with her team delivering the testing kit in a record time of six weeks.

Bhosale gave birth to a baby girl just a day before submitting the kit to the authorities for evaluation.

"It was like giving birth to two babies," Bhosale told PTI over the phone.

The virologist said both the journeys - that happened in parallel - were not without challenges.

"There were complications in the pregnancy while work on the test kit was on. The baby was delivered through cesarean," she said.

Bhosale said she felt that it was the right time to serve the people to help them in combating the coronavirus threat.

"I had been working for five years in this field and if I don't work in emergency situations when my services are needed the most, then what is the use?" she said.

Though Bhosale was not able to visit the office due to the pregnancy, she was guiding a team of 10 persons working on the project at Mylab Discovery in Pune.

The strong bonds forged with the team over the years and their support made it possible, she said.

Company's co-founder Shrikant Patole said just like drug discovery, test kits too go through a lot of quality checks to improve the precision.

He credited Bhosale for the success of the project.

The COVID-19 testing kit delivered by Bhosale's team will reduce the time taken for delivering a result to 2.5 hours from the prevalent practice of eight hours.

A pioneering approach to testing without compromising on the results was adopted, Bhosale said.

The Maylab test kit will cost Rs1,200, a quarter of Rs 4,500 per kit that the government has been spending on testing so far.

"I'm happy that I could do something for the country," Bhosale said.

As of Friday, only 27,000 of the 1.3 billion people were tested for the virus in the country.

According to experts, high scale testing is essential because it alone can ensure an early diagnosis of COVID-19 and lower down the fatalities.

The company is confident of ramping up the capacity at its plant in Lonavala to deliver 100,000 kits a week, Patole said.

He said the authorities are helping the company, including giving priority for shipping of the raw materials.

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
