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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Dubai, Apr 14: Around 2,500 Indians have approached Indian missions in the United Arab Emirates (UAE) seeking help to be flown home during the ongoing coronavirus lockdown, top diplomats have said.

The Indian Embassy in Abu Dhabi and the Indian Consulate in Dubai together have received requests from "a little more than 1,000 individuals" while the latter has received an additional request from an employer who has laid-off around 1,000 Indian workers, reports Gulf News on Monday.

According to the Indian Ambassador to the UAE Pavan Kapoor, the missions have not been bombarded with mass requests from the people who wish to take an immediate flight home unlike widespread reports on social media.

Most of the individuals who have expressed their interest to return home are visitors and those who lost their jobs, he told Gulf News.

Consul General of India in Dubai, Vipul said his mission had received nearly 1000 requests via email and phone from people who want to return home.

"A majority of them are visit visa holders. On Sunday, we got information about another large group of around 1,000 Indian workers who have lost jobs. The employer has got in touch to know the options to send them back home as early as possible," he told Gulf News.

However, the diplomatic heads refuted unverified reports that claim tens of thousands of Indians were scrambling to fly home during the pandemic.

They added that the missions have been aiding hundreds of workers, who have been left in the lurch by their employers, with provisions.

The Indian government had said that flight services cannot be resumed during the lockdown period, which has now been extended till May 3.

Mangaluru, Feb 7: To stop the NRC and CAA from being implemented everyone has to fight unitedly highlighting the failures of the ruling party, said National President of Priyadarshini squad, All India National Women’s Congress Kavya Narasimha Murthy.

Addressing the workshop for the protection of Citizenship against CAA, NRC and NPR for the party workers at the Cordel Hall, Kulshekar here Thursday by district Congress party, she said, “Protests are being held everywhere against the CAA, NRC and NPR but if we only go on protesting, the ruling party will implementing divisive policies and new laws every day.

Many think that they may not be affected by the CAA, NRC or NPR and keep away from protesting against it. The congress should fight against the CAA concentrating on three approaches. We cannot fight against divisive politics by fighting only against the CAA and NRC. We need to expose the government’s failures, their divisive politics and continue our protests against the CAA, NCR and NPR.”
