Karnataka govt to pay fees of school, college students in flood-hit Kodagu

The current physical distancing guidelines provided by the World Health Organisation (WHO) and by the US Centers for Disease Control and Prevention (CDC) may not be adequate to curb the coronavirus spread, according to a research which says the gas cloud from a cough or sneeze may help virus particles travel up to 8 metres. The research, published in the Journal of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.

Study author, MIT associate professor Lydia Bourouiba, warned that droplets of all sizes can travel 23 to 27 feet, or 7-8 metres, carrying the pathogen.

According to Bourouiba, the current guidelines are based on "arbitrary" assumptions of droplet size, "overly simplified", and "may limit the effectiveness of the proposed interventions" against the deadly pandemic.

 She explained that the old guidelines assume droplets to be one of two categories, small or large, taking short-range semi-ballistic trajectories when a person exhales, coughs, or sneezes.

However based on more recent discoveries, the MIT scientist said, sneezes and coughs are made of a puff cloud that carries ambient air, transporting within it clusters of droplets of a wide range of sizes.

Bourouiba warned that this puff cloud, with ambient air entrapped in it, can offer the droplets moisture and warmth that can prevent it from evaporation in the outer environment.

"The locally moist and warm atmosphere within the turbulent gas cloud allows the contained droplets to evade evaporation for much longer than occurs with isolated droplets," she said.

"Under these conditions, the lifetime of a droplet could be considerably extended by a factor of up to 1000, from a fraction of a second to minutes," the researcher explained in the study.

The MIT scientist, who has researched the dynamics of coughs and sneezes for years, added that these droplets settle along the trajectory of a cough or sneeze contaminating surfaces, with their residues staying suspended in the air for hours.

"Even when maximum containment policies were enforced, the rapid international spread of COVID-19 suggests that using arbitrary droplet size cutoffs may not accurately reflect what actually occurs with respiratory emissions, possibly contributing to the ineffectiveness of some procedures used to limit the spread of respiratory disease," Bourouiba wrote in the study

Bengaluru, Apr 21: Hardline BJP leader and Bengaluru South MP Tejasvi Surya, who had deleted some of his old sexist tweets while contesting for Lok Sabha polls, yesterday deleted deleted his ugly remarks against Arab woman after it went viral and triggered sharp response from  many quarters, including from the Arab world.

In 2015, before Surya became an MP, he had said in a tweet, "95% of Arab women have never had an orgasm in the last few hundred years! Every mother has produced kids as an act of sex and not love. @Tarek Fatah."

The old tweet was picked up some influential members in the Arab community. Many intellectuals and various members of the royal families too have over the past few days condemned the attacks on Muslims in India and called out instances on Islamophobia. They have been highlighting derogatory comments about the Arab community purportedly made by supporters of the ruling BJP. It was then that a few found that even present day recognised leaders like Tejasvi had made similar comments in the past.

As the outrage grew, Tejasvi deleted the old tweet. A lot of BJP supporters on Twitter then started pointing out that Tejasvi Surya had merely quoted Canadian journalist Tareh Fatah, known for his anti-Islam comments. But by then someone had archived the tweet and Tejasvi's response to it in 2015.

Dear @Twitter , this Indian politicians @Tejasvi_Surya has racially slurred Arab women, I wonder how is his account still active? Is it not against Twitter's official policy? Please act as Arab sentiment has been badly wounded. pic.twitter.com/JAM3hnDEjN

In a thread to the same tweet, responding to criticism, Surya had said that these were not his opinion but attributed to Tarek Fatah. He also said that he agrees with Fateh's position that 'Islamofascism was a threat to all civilsations'.

Surya could not be reached for a comment.

However, a source close to Surya, said, "This is a 2015 tweet where Tejasvi Surya was quoting Tarek Fatah from an interview. It is being wrongly attributed to him with malicious intent. The main issue being addressed in the interview was about the barbaric and inhuman practice of genital mutilation of women. If there's any person to comment on it, it has to be Tarek Fatah."

Tejasvi Surya had landed in a similar controversy soon after his nomination as a candidate just ahead of the 2019 Lok Sabha elections.

The Congress also stepped in to criticise Surya and the BJP, national spokesperson Sanjay Jha said in a tweet, “The BJP gives tickets to Pragya Singh Thakur and #TejasviSurya etc because it helps popularise their hardline bigoted political profile. But the chickens usually come home to roost. Today, India stands embarrassed, humiliated.”

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.
