AAP leaders stay away from rebels' meet

Kolkata, Jan 15: The arrows of Mahabharata's Arjuna had atomic power, claimed West Bengal Governor Jagdeep Dhankhar, drawing sharp criticism from academicians, even as he joined a long list of politicians who have in recent years given bizarre interpretations linking mythology with science.

Speaking at the 45th Eastern India Science Fair and 19th Science and Engineering Fair on Tuesday, Dhankhar also claimed that flying objects existed during the period of Ramayana.

"It is said that the plane was invented in 1910 or 1911, but if we delve into our old scriptures we will see in Ramayana, we had 'uran khatola' (aircraft)," he said.

"Sanjaya narrated the entire war of Mahabharata (to Dhitarasthra) not from TV. The arrows of Arjuna in Mahabharata had atomic power in it," Dhankhar said, asserting that the world can no longer afford to ignore India.

According to Sanskrit epic Mahabharata, Sanjay, even after staying away from the battlefield, had narrated what was happening there to Dhritarashtra, who was blind.

Dhankhar, who has been in news for clashes with the Mamata Banerjee government ever since he assumed office in July last year, joins politicians such as Tripura Chief Minister Biplab Deb and UP deputy chief minister Dinesh Sharma to give odd interpretations of mythology.

While Deb had claimed that the internet existed during Mahabharata, Sharma suggested that godess Sita was a test tube baby.

Recently, Puducherry Lt Governor Kiran Bedi was trolled online for sharing a doctored video that claimed, "NASA recorded sound of sun -- Sun chants Om".

Indologist Nrisingha Prasad Bhaduri said governors appointed by the BJP government at the Centre are delving into everything and behave "as if they are know-alls".

"They fail to understand one thing that great writers have very strong power of imagination," Bhaduri said.

Scientist Sandip Chakraborty said such comments only hurt the scientific progress in India at the global forum.

"The ancient writers described all these things based on their imagination. It is true that India made a lot of progress during the ancient period, but such comments only damages the progress made by our scientific community," he said.

Chennai, Apr 25: Civic authorities on Saturday turned down a plea for exhuming the body of a doctor who died of COVID-19 here and burying it in another cemetery, citing health experts' view that it was unsafe to do so. Citing a request from the wife of the deceased doctor to allow exhumation and then re-burial at a cemetery in Kilpauk, the Greater Chennai Corporation said it sought a report from a committee of public health experts to ascertain the feasibility of entertaining her plea.

The spouse of the doctor had appealed to the GCC on April 22 to exhume and bury again her husband's body. She had said that burial in the Kilpauk cemetery here was her husband's last wish and he had conveyed it to her before he was put on a ventilator.

The report of experts has said that "it is not safe" to exhume and again bury the body of a COVID-19 victim and hence "it is not possible to accept her request," the GCC said in an official release. On April 19, a city-based 55-year-old neurosurgeon died of coronavirus and his burial at the Velangadu crematorium here was marred by violence.

A mob which falsely feared that the burial may lead to the spread of contagion had attacked the corporation health employees and associates of the deceased doctor. The doctor's wife and son also had to leave the burial ground in view of the violence.

The body was brought to Velangadu as people of Kilpauk area had opposed his burial there. Over a dozen men involved allegedly in violence were arrested and remanded to judicial custody. Later, in a video message, the surgeon's wife had said that it was her husband's last wish to be interred at the Kilpauk cemetery as per Christian rituals

Chief Minister K Palaniswami and DMK president M K Stalin had spoken to her on Wednesday over the phone and condoled her husband's death.

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
