Lot of evidence to prove that you are a terrorist: BJP to Arvind Kejriwal

New Delhi, Apr 19: The government on Sunday prohibited the sale of non-essential items through e-commerce platforms during the ongoing lockdown, four days after allowing such companies to sale mobile phones, refrigerators and ready-made garments.

Union Home Secretary Ajay Bhalla issued an order excluding the non-essential items from sale by the e-commerce companies from the consolidated revised guidelines, which listed the exemption given to the services and people from the purview of the lockdown.

The order said the following clause "E-commerce companies. Vehicles used by e-commerce operators will be allowed to ply with necessary permissions" is excluded from the guidelines.

The previous order had said such items were allowed for sale through e-commerce platforms from April 20.

However, the reason for reversing the order is not known immediately.

New Delhi, May 23: The nationwide lockdown will no longer help India in its fight against COVID-19, and in its place community-driven containment, isolation and quarantine strategies have to be brought into play, leading virologist Shahid Jameel said.

The recipient of Shanti Swarup Bhatnagar Prize for Science and Technology also stressed that testing should be carried out vigorously to identify coronavirus hotspots and isolate those areas.

"Our current testing rate at 1,744 tests per million population is one of the lowest in the world. We should deploy both antibody tests and confirmatory PCR tests. This will tell us about pockets of ongoing infection and past (recovered) infection. This will provide data to open up gradually and let economic activity resume," Jameel told PTI in an interview.

He stressed that testing has to be dynamic to continuously monitor red, orange and green zones and change these based on that data.

About community transmission of COVID-19 in India, Jameel said the country reached that stage long ago.

"We reached community transmission a long time ago. It's just that the health authorities are not admitting it. Even ICMR's own study of SARI (severe acute respiratory illness) showed that about 40 per cent of those who tested positive for SARS-CoV-2 did not have any history of overseas travel or contact to a known case. If this is not community transmission, then what is?" he posed.

Lockdown bought India time in its fight against coronavirus, but continuing it is unlikely to yield any further dividend, Jameel said.

"Instead, community-driven local lockdowns, isolations and quarantines have to come into play. Building trust is most important so that people follow rules. A public health problem cannot be dealt with as a law-and-order problem."

The nationwide lockdown, initially imposed from March 25 to April 14, has been extended thrice and will continue at least till May 31. The virus has claimed 3,720 lives and infected over 1.25 lakh people in the country so far.

Jameel has expertise in the fields of molecular biology, infectious diseases, and biotechnology. He is the CEO of Wellcome Trust/Department of Biotechnology's India Alliance and is best known for extensive research in Hepatitis E virus and HIV.

He said COVID-19 will eventually be controlled through herd immunity, which is acquired in two ways – when a sufficient fraction of the population gets infected and recovers, and with vaccination.

"It is estimated that for SARS-CoV-2 at least 60 per cent of the population would have to be infected and recovered, or vaccinated. This will happen over the course of the next few years," Jameel said.

Herd immunity is reached when the majority of a population becomes immune to an infectious disease, either because they have become infected and recovered, or through vaccination. When that happens, the disease is less likely to spread to people who aren't immune, because there just aren't enough infectious carriers.

"India has 1.38 billion people, a population density of about 400/sq km and a healthcare system ranked at 143 in the world. If we allow 60 per cent people to get infected quickly in the hopes of herd immunity, that would mean 830 million infections," Jameel said.

"If 15 per cent need hospitalization that means about 125 million isolation beds (we have 0.3 million). If five per cent need oxygen and ventilatory support, this amounts to about 42 million oxygen support and ICU beds; we have 0.1 million oxygen support beds and 34,000 ICU beds. This would overwhelm the healthcare system causing mayhem," he said.

Jameel said if the population level mortality is 0.5 per cent that would mean 40 lakh deaths. "Are we prepared to pay this price for herd immunity in the short term? Clearly not," he said.

He said it is unlikely that a vaccine would be available by the end of the year.

"Even then, we don't know yet how long it would give protection – weeks, months, one year, a few years? I don't think we will return to pre-coronavirus days for at least the next 3-5 years. This is also a chance to evaluate if we want to return to those unsustainable, environment-damaging ways. COVID-19 is a timely warning to reform our way of living," he said.

Jameel said it is hard to predict but plausible that COVID-19 would return in second or third wave.

"Later waves come when we don't understand the disease and become lax. A comparison to Spanish Flu is not entirely valid because in 1918 no one knew what caused it. No one had seen a virus till the mid-1930s as the electron microscope needed to view those was invented in 1931," he said.

"Today we know a lot more about the pathogen, its genetic makeup, how it transmits and how to prevent it. We need to be sensible and follow expert advice," he said.

If there is any scientific evidence linking deforestation, rapid urbanisation, climate change with pandemics like COVID-19, he said zoonotic viruses -- those that jump from animals to humans -- happen so when wild animal–human contacts increase.

"Deforestation destroys animal habitats bringing them closer to humans. When you cut forests, bats come to roost on trees closer to human habitations. Their viruses in secretions/stool get transmitted to domestic animals and on to humans. This happened clearly with Nipah virus outbreak in Malaysia in 1997-98 from fruit bats to pigs to humans," he said.

"COVID-19 possibly arose in wet animal markets due to dietary habits that bring all kinds of live and dead wild animals in close contact with humans," Jameel added.

New Delhi, Jan 24: Although India's Ujjwala programme encouraged adoption of liquefied petroleum gas (LPG) for cooking among the poor, households availing the scheme have not shifted away from using highly polluting fuels like firewood, a study reveals.

The researchers, including those from the University of British Columbia (UBC) in Canada, found that additional incentives to encourage regular use of cooking gas are necessary for a complete transition to clean cooking fuel among poor rural households.

They noted that about 2.9 billion people across Asia, Africa, and Latin America burn solid fuels like firewood to meet their cooking energy needs.

This has significant negative implications for public health, the environment, and societal development, according to the researchers.

Through the Pradhan Mantri Ujjwala Yojana (PMUY), India has provided capital cost subsidies to poor women to adopt a clean-burning cooking fuel or LPG.

The researchers explained that within the first 40 months of the scheme, more than 80 million households obtained LPG stoves.

However, the full benefits of LPG adoption depend on near complete replacement of polluting fuels with LPG, according to a research-based policy brief published in the journal Nature Energy.

The scientists said this cannot be assumed solely on the basis of LPG presence in the household.

"Our research shows that Ujjwala was able to attract new consumers rapidly, but those consumers did not start using LPG on a regular basis," Abhishek Kar, a postdoc at Columbia University in the US, told PTI.

The study analysed LPG sales data for over 25,000 consumers, including PMUY beneficiaries, as well as general rural LPG consumers in Koppal district of Karnataka.

The scientists employed data covering all LPG purchases of PMUY beneficiaries through their first year in the programme.

They also assessed the general rural population's purchases during their first five years as consumers to assess the effect of experience on use.

The findings estimate that an average rural family needs to purchase five 14.2 kilogramme-cylinders annually to meet half of their cooking needs.

However, the study said just seven per cent of PMUY beneficiaries in Koppal purchased five or more cylinders annually, suggesting that the beneficiaries seldom use LPG.

The general (nonPMUY) consumers in this region use on average two times more LPG cylinders than PMUY beneficiaries, the researchers noted.

Yet, only 45 per cent of nonPMUY consumers use five or more cylinders per year -- even after several years of experience with LPG, they said.

The team assessed price and seasonal factors affecting LPG use among the general population over a three-year period.

It found that LPG consumers are sensitive to price and seasonality -- LPG cylinder refill rates are lower in the summer when agricultural activity is limited, and cash is scarce.

"There was no scheme incentives to promote use, except general LPG subsidies which is available to all, including the urban middle class," said Kar, who was a Ph.D. scholar at UBC when the research was published.

"If there is no additional income, what cost would a poor family on an already tight budget cut to pay for an extra expense on a regular basis.

"Ujjwala has started the scheme of 5 kg-cylinder in response, but the impact of that on LPG sales is still publicly unknown," he said.

These findings, the researchers noted, suggest the need for additional measures to promote regular LPG use for all rural populations.

Although the finding come from a single district in Southern India, it may also apply to other areas with similar socio-economic conditions, they said.

A more expansive evaluation of PMUY would help design targeted incentives to transform infrequent users to regular users, according to the researchers.
