UAE court issues worldwide freezing order on BR Shetty’s assets

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

New Delhi, Jun 6: With the coronavirus pandemic showing no signs of abating, it seems unlikely that Muslims from India will be able to undertake the Hajj pilgrimage this year.

However, the government will take a final decision on the matter only after Saudi Arabia makes its position on hosting the pilgrimage clear.

A circular issued by the Hajj Committee of India on Friday said only a few weeks are left for the preparatory work in India for Hajj 2020, yet the Saudi authorities have not communicated any further development regarding the pilgrimage.

"In view of the several inquiries received and concerns expressed over uncertainty over Hajj 2020, it has been decided by the Hajj Committee of India that, those pilgrims who desire to cancel their Hajj journey this year, their 100 per cent amount paid so far will be refunded without any deductions," the circular issued by Hajj Committee of India CEO Maqsood Ahmed Khan said.

"Coronavirus cases are increasing in Saudi Arabia and two lakh people have to go from here. We had made preparations, but now there is very little time left. We are waiting for an official word from Saudi Arabia," a top source said.

In response to a question, the source said, "This time, it is unlikely that people will be able to undertake Hajj from India."

Uncertainty has been looming large over this year's Hajj in the wake of the coronavirus pandemic and though Saudi Arabia has not made a decision on whether the annual pilgrimage will be held or not, it did ask Muslims to delay their bookings till there is more clarity.

The bilateral annual Hajj 2020 agreement between India and Saudi Arabia was signed last December. In 2020, a total of 2 lakh Indian Muslims were expected to perform Hajj.

Over 95,000 COVID-19 cases and more than 600 deaths have been reported in Saudi Arabia due to the coronavirus pandemic, according to Johns Hopkins University data.

Some countries have decided not to send their people for Hajj this time. The most prominent among these is Indonesia, the country with the largest Muslim population in the world.

The Hajj 2020 is proposed in the period between late July and early August.

The Hajj is one of the five pillars of Islam which every Muslim is required to complete at least once in their lifetime if they are healthy enough and have the means to do so.
