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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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
Anant Kumar Dattatreya Hegde, a member of parliament, who represents coastal Karnataka's Uttara Kannada constituency, in a press meet at his native Srisi on Sunday stated that terrorism could not be wiped out as long as Islam remained in this world.

Mr.AKD...just asks with your own Hindu Brothers & sisters those who live in Arabian Sand , how they enjoy their peace life with their family & children in Muslim countries ! Then you will come to know the real fact of terrorism.
COMMUNAL RAGAV, GO TO NEPAL FOR FREEDOM SPEECH ,///// WE NEED PEACE HERE,, [JAI HIND]
one more idiot appears in chaddi parivaar.
This stupid is dangerous to peace loving Hindu society
You better try yourself rather than asking others to do it. Most of the people in BJP are gone mad. O Hegde Islam is near to your door step. Come out if you dare to know the beauty of Islam.
Metal Manja This MP,
More you try to wipe out more it spreads
This RSS dog is trying to spread virus poison at Uttara Kannada surroundings. Hope peace loving Kannadiga's will kick him from power shortly.
All are well aware these are the special training from his dirty nagpur base.
But rss will never succeed fro any angle.
He is in the state of \vitiated by perversity nature\""
Where is the commnet from Ibraheem Hussain Udupi.
We muslims fuck you anthya kumra hedge...

Islam is the religion which brings peace and tranquility to entire human kind, now it is your turn to accept Islam and do some good things, otherwise you will have to taste hell fire hereafter. Also you have to believe in last and final messenger of Allah \Mohammed Sallalahu Alaiwassallam\".....
