With highest single-day spike of 28,637 cases, India's COVID-19 tally reaches 8,49,553

Jun 13: Requiring the wearing of masks to prevent the spread of the novel coronavirus in areas at the epicenter of the global pandemic may have prevented tens of thousands of infections, a new study suggests.

Mask-wearing is even more important for preventing the virus' spread and the sometimes deadly COVID-19 illness it causes than social distancing and stay-at-home orders, researchers said, in the study published in PNAS: The Proceedings of the National Academy of Sciences of the USA.

Infection trends shifted dramatically when mask-wearing rules were implemented on April 6 in northern Italy and April 17 in New York City - at the time among the hardest hit areas of the world by the health crisis - the study found.

"This protective measure alone significantly reduced the number of infections, that is, by over 78,000 in Italy from April 6 to May 9 and over 66,000 in New York City from April 17 to May 9," researchers calculated.

When mask-wearing went into effect in New York, the daily new infection rate fell by about 3% per day, researchers said. In the rest of the country, daily new infections continued to increase.

Direct contact precautions - social distancing, quarantine and isolation, and hand sanitizing - were all in place before mask-wearing rules went into effect in Italy and New York City. But they only help minimize virus transmission by direct contact, while face covering helps prevent airborne transmission, the researchers say.

"The unique function of face covering to block atomization and inhalation of virus-bearing aerosols accounts for the significantly reduced infections," they said. That would indicate "that airborne transmission of COVID-19 represents the dominant route for infection."

The U.S. Center for Disease Control and Prevention on Friday urged organizers of large gatherings that involve "shouting, chanting or singing to strongly encourage the use of cloth face coverings to lower the risk of spreading the coronavirus."

New Delhi, Feb 29: Former Union Minister M J Akbar told a Delhi court on Friday that journalist Priya Ramani had defamed him by calling him with adjectives such as 'media's biggest predator' in the wake of #MeToo movement in 2018 that harmed his reputation.

M J Akbar made the allegations before Additional Chief Metropolitan Magistrate Vishal Pahuja through his lawyer during the final hearing of a private criminal defamation complaint filed by him against Priya Ramani. Akbar resigned as Union minister on October 17, 2018.

Ramani in 2018 accused Akbar of sexual misconduct around 20 years ago when he was a journalist.

Senior advocate Geeta Luthra, appearing for Akbar, said that the allegations were intentional and malafide.

“When you call someone media's biggest predator, it is per se defamatory. Calling a person with such adjectives is on the face of it defamatory. In the eyes of the people, Akbar's reputation was harmed... The per se effect was lowering of my (Akbar) reputation in the eyes of the right thinking members of the society,” she told the court.

She said there was no due process in the allegations. “It has a cascading effect. Embarrassing questions were asked. I (Akbar) am a person of greatest integrity... There was no due process in the allegations. You cannot just make allegation and let that person suffer,” she added.

Luthra said that if there was any grievance, it had to be raised then and there before the appropriate authority.

“We need to realise the effect has what we say or what we do. It's not like she went to any authority or raised any grievance. Opportunity was there, rights were there but to attack so person behind their back on social media...knowing that his whole life will be adversely affected? It's not right,” she said.

M J Akbar has denied all the allegations of sexual harassment against the women who came forward during #MeToo campaign against him.

Akbar had earlier told the court that the allegations made in an article in the 'Vogue' and the subsequent tweets were defamatory on the face of it as the complainant had deposed them to be false and imaginary and that an “immediate damage” was caused to him due to the “false” allegations by Priya Ramani.

Ramani had earlier told the court that her “disclosure” of alleged sexual harassment by Akbar has come at “a great personal cost” and she had “nothing to gain” from it.

She had said her move would empower women to speak up and make them understand their rights at workplace.

Several women came up with accounts of the alleged sexual harassment by M J Akbar him while they were working as journalists under him.

He has termed the allegations “false, fabricated and deeply distressing” and said he was taking appropriate legal action against them.

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.
