Hindus ‘hurt’ as Amazon CEO Jeff Bezos shown as Vishnu idol

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Newsroom, May 22: Countless netizens including Indians have hailed the action taken by Jazan University of Kingdom of Saudi Arabia against a high-ranking Indian expatriate who had posted called Indian Muslims as radicals.  

Social media platforms such as Twitter and Facebook flooded with appreciation after the University announced on Twitter that the professor, who had posted objectionable messsages, had been fired. The university, however, did not disclose the name of the professor. 

On its Twitter account, Jazan University wrote, “Based on what was monitored by the university about the publication of a contracted faculty member for offensive posts and tweets, his registration has already been folded. #JazanUniversity affirms that it resolutely addresses any perverted or extremist ideas that affect the constants or violate the directions of good leadership.”

After the university’s announcement, many on Twitter posted screenshots of the communal tweets claiming that the professor is Neeraj Bedi and made it clear that the dismissed professor is an Indian.

Bedi has been working as full time Professor in Faculty of Public Health and Tropical Medicine in Jazan University for years.

In his Twitter account, which does not currently exist, he was praising PM Modi and spewing poison against Islam and holding Muslims responsible for the spread of Coronavirus. It is believed that the account was deleted after the protests became severe.

Udupi, May 21: In a shocking development, as many as 27 fresh coronavirus positive cases were reported in the coastal district of Udupi today. 

Another shocker is, 16 among 27 covid-19 patients are children. The rest are six men and five women. 

Interestingly, all of them have inter-state travel history. 23 had come from Maharashtra and 3 from Telangana. Another one had come from Kerala to Manipal. More details are awaited.
