Modi asks BJP MPs, MLAs to submit account statement post demonetisation

New Delhi, May 15: Union Health Minister Harsh Vardhan has appealed to all states and Union Territories to ban the sale of smokeless tobacco products and spitting in public places in line with the orders of the Rajasthan and Jharkhand governments to prevent the spread of coronavirus infection.

In a letter to all state health ministers, Vardhan said smokeless tobacco users have a tendency to spit in public places or otherwise and therefore, increase health risks especially those of spreading contagious diseases like COVID-19, tuberculosis, swine flu, encephalitis and others.

"Use of smokeless tobacco also creates an unhygienic environment which further spreads the diseases. The large gathering at the retail outlets where smokeless tobacco products are sold, also pose the risk of spread of COVID-19," he said.

In the letter dated May 11, the Union minister underlined that tobacco use is a major threat to public health globally. He also mentioned the Indian Council of Medical Research's (ICMR) appeal to the public not to consume and spit smokeless tobacco products in public places.

Chewing tobacco products and areca nut increases the production of saliva followed by a very strong urge to spit. Spitting in public places could enhance the spread of the COVID-19, Vardhan said.

"By banning spitting in public places, states and UTs can help in achieving not only Swachh Bharat but also Swasth Bharat (Clean India and Healthy India)," he said.

Vardhan also mentioned the May 1 guidelines issued by the Union Home Ministry under the National Disaster Management Act, 2005, which stipulate that "spitting in public places shall be punishable with fine as may be prescribed by the state/UT local authority and consumption of liquor, pan, gutkha, tobacco etc in public places is not allowed".

Appreciating the efforts of Rajasthan and Jharkhand in this direction, the Union Health Minister urged all states to take similar measures and create widespread awareness regarding the harm of spitting in public places.

The Rajasthan government had by an ordinance banned spinning in public places and sale of paan, gutka and tobacco in the wake of the coronavirus outbreak. The Jharkhand too has imposed a complete ban on all types of tobacco products to prevent spitting in public places that could increase the spread of coronavirus infection.

"I am happy to note that the governments of Jharkhand and Rajasthan have already completely banned the sale of tobacco products and spitting in public places. Therefore, I urge upon you to take similar measures and also create widespread awareness in your state/ UT regarding harms of spitting in public places.

"It is also requested that the directions of Ministry of Home Affairs in this regard may be implemented scrupulously and effectively," Vardhan said in the letter.

Tobacco smoking is a known risk factor for many respiratory infections and increases the severity of related diseases. A review of studies by public health experts convened by WHO on April 29 found that smokers are more likely to develop severe diseases, compared to non-smokers, said Binoy Mathew, senior programme officer of Voluntary Health Association of India.

It is one of the main risk factors for a number of chronic ailments, including cancer, lung and cardiovascular diseases, he said, adding that according to the Global Adult Tobacco Survey, with 268 million or 28.6 per cent of all adults in India, the country has the second largest number of tobacco users in the world.

At least 12 lakh die from tobacco-related diseases every year, Mathew said.

Those keen to quit smoking and smokeless products can avail of free of charge telephone-based services launched by the government. The Ministry of Health has set up a National Tobacco Quit Line Services to provide counselling services to help tobacco consumers quit the habit.

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
