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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, May 13: Kinz Foundation started distributing around 1500 food packets daily for migrant workers migrating in different parts of Dakshina Kannada district amidst coastal coronavirus lockdown.

"We are distributing daily 1,500 food packets both vegetarian and non-vegetarian. The number will be increased to 5,000," said businessman Althaf Hussain who arranged food packets on May 13.

"These are trying times. The poor migrants who are being denied of their bread due to the lockdown deserve help and we are trying to bring them food which is most basic needs.” he added.

Bengaluru, May 4: Booze lovers ushered in the resumption of liquor sales in a spirited fashion in Karnataka onMonday thronging stores hours before shutters went up at severalplaces and made no secret of their celebratory mood.

At some places, they flocked liquor shops even before day-break and performed "special prayers" with flowers, coconuts,incense sticks, camphor and crackers in front of the stores.

Liquor outlets had been shut in the State from March 25 following the lockdown due to the COVID-19 pandemic.

Excise revenue loss during the period was about Rs 2,500 crore, according to government sources.

About 4,500 standalone liquor outlets (CL-2 and CL- 11licence holders), which comprise wine stores and those owned bystate-run Mysore Sales International Limited, outside containmentzones were allowed to be opened from Monday from 9 am to 7 pm withsome restrictions.

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.
