Cong slams Yogi for campaigning in Karnataka after dust storm hits UP

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Mangaluru/Udupi, May 20: The twin districts of coastal Karnataka today reported seven new coronavirus cases. Six cases were reported from Udupi district and one from Dakshina Kannada.

The woman had travelled from Rajajinagar in Bengaluru along with her son to Mangaluru on May 10.

She was suffering from Asthma and respiratory problems. She was admitted to Wenlock COVID hospital on May 17.

Dubai, Apr 11: An Indian expat in the UAE is facing police action for allegedly insulting Islam on social media in response to a Facebook post on the coronavirus, according to a media report.

Rakesh B Kitturmath, who worked as a team leader at Emrill Services, an integrated facilities management (FM) headquartered in Dubai, was sacked on Thursday after his post sparked outrage on social media, the Gulf News reported.

“Kitturmath’s employment stands terminated with immediate effect. He will be handed over to Dubai Police. We have a zero-tolerance policy towards such hate crimes,” said Stuart Harrison, CEO of Emrill Services.

"As an organisation, we have worked hard over the years to embrace diversity and create a culture of inclusion, where every nationality, religion and background is welcomed and celebrated. We have a strict social media policy for our employees to ensure they respect our values, both inside and outside of work," the newspaper quoted Harrison as saying.

Harrison said they are trying to find out if Kitturmath was still in the UAE, according to the report.

“We have over 8,500 employees so this may take a while. That said, we have fired him. If he’s still in the country, he will be handed over to Dubai Police,” he said.

Originally from Ranebennuri, Karnataka, Kitturmath joins an ever-growing list of Indian ex-pats who have landed in trouble for alleged Islamophobic messages in recent days.

Earlier this week, Abu Dhabi resident Mitesh Udeshi was sacked for posting a cartoon mocking Islam on his Facebook page while a police complaint was filed against Sameer Bhandari of Future Vision Events & Weddings’ in Dubai after he asked a Muslim job seeker from India to go back to Pakistan.

The UAE outlaws all religious or racial discrimination under a legislation passed in 2015.

The anti-discrimination/anti-hatred law prohibits all acts “that stoke religious hatred and/or which insult religion through any form of expression, be it speech or the written word, books, pamphlets or via online media.”
