Flight chartered by SAQCO brings stranded Kannadigas from Dammam to Mangaluru

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jun 18: Former Karnataka Chief Minister and Congress leader Siddaramaiah has accused the BJP-led government of not passing the benefit of the low price of crude to the common man and urged Prime Minister Narendra Modi to take steps to bring down prices of petroleum products.

Hitting out at the BJP-led government, he termed it as "opportunistic" and said the price of petroleum products were being increased when people were facing difficulties due to COVID-19.

"It is very disheartening to witness and unprecedented opportunistic government which is trying to extract every pound and flesh from the common man, that too when the whole country is suffering from the COVID-19 pandemic. This is in the backdrop of the continuous price hike in the last 10 days," said the letter was written on Wednesday.

The Congress leader said that the policy decisions taken by the government "with respect to managing fuel sources are inconsistent with the prudent measures generally adopted".

"When the price of crude oil was remarkably low in March, April and May 2020, your government was very reluctant to pass on the benefits to the people by reducing the fuel prices proportionately, but, instead, your government continued to capitalise by increasing the excise duty," he said.

He said the government had also "failed" in the last six years to increase the oil storage capacity which could have been used for the country's advantage when the international crude oil price fell really low.

He said the government should roll back the excise duty and help in the reduction of fuel prices.

"The reduced burden will help the common man to have additional money in hand that will be spent on essential goods and services which will ultimately help them tide over these difficult times," he said.
