Coronavirus can go up to 8 metres from exhalation, linger in air for hours: MIT scientist

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

These include customers compulsorily wearing of facemasks andmaintaining social distancing with not more than five people inside liquor shops.

Many customers were indeed well-prepared.

At many places, they came with umbrella, raincoat, newspapers and books and queued up as early as 3 am.

At a liquor shop in Salegame Road in Hassan, the tipplers lit the traditional lamp and incense sticks, performed 'aarati'with camphor and decorated the store with the garland of flowers.

With folded hands, they all performed 'special prayers'.

In Mandya, the tipplers queued up before Martaanda liquor shop before dawn.

An hour before the sales were to resume, a few people burst crackers in celebration.

Some tipplers in Belagavi were more "enterprising."

They wentto a liquor store on Sunday night itself, performed special prayersand placed their "representatives" in the form of slippers, bags and stones in the "social distancing boxes" they themselves had drawn sothat they don't have to stand in queue in the morning.

An elderly woman Dakamma was the centre of attraction in Shivamogga.

The bent body did not bend the determination of this spirited lady, claimed to be 96-year-old, who was heard saying "liquor is goodfor health."

At the taluk headquarters town of Brahmavara in the coastal Udupi district, the queue of the booze lovers was reported to be almost half-a-kilometre.

Long queues were seen at liquor stores at Mariyappana Palya and K R Puram, among others, in Bengaluru.

The store managers too were no less cautious while dealing with customers in the COVID era.

They let the customers enter after spraying sanitisers in their hands, and allowed only those who hadworn masks and maintained social distancing.

To maintain law and order, authorities had deployed policemen in good numbers at these stores and they were seen on duty ensuring  that customers maintained social distancing.

Coimbatore, June 1: A communal conspiracy has been aborted by the police by arrested a miscreant who had placed meat in front of Venugopala Krishnaswamy Temple and Sri Ragavendra Temple in Coimbatore, Tamil Nadu.

The miscreant has been identified as S Hari Ramprakash, 48, of Kavundampalayam in Coimbatore. He is a civil engineering graduate. It is suspected that He is a Sangh Parivar activist and the intention behind his act was to put the blame on Muslims.

Even though officials claimed that Hari appeared to be mentally disturbed, there were no medical records that stated he was mentally disturbed.

Two separate cases were registered against Hari. He was booked under sections 153 A (promoting enmity between different groups) 295 A (deliberate and malicious acts intended to outrage religious feelings of any class by insulting its religion or religious beliefs) and 298 (uttering words etc, with deliberate intent to wound religious feelings) of the Indian Penal Code.

City police commissioner Sumit Sharan said, “We collected CCTV footage and found a man, who had parked his motorcycle near the two temples and returned from the temples. Based on the registration number, we traced and arrested Hari.”

Commissioner added that the city has CCTV cameras in many places and it helped police officials crack the case faster. The police said he purchased one kg of pork meat from a shop at Kavundamapalaym last Friday morning and placed it in front of the temples on the same day.
