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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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
Mahesh S Patil, the judge of second additional civil court and JMFC, Managluru, ruled that Mr Uchil should be given a compensation of Rs 50,000 along with interest at the rate of 9% per annum from the date of suit till the actual payment towards damages.

Dear Mr Rahim,
Congrats on winning the law suit.
In my opinion, you dont have to listen to the negative comments, especially to that of you receive from bearies. It doesn't matter which political party you belong to, as long as you do good service to the society.
They advise you on how to be 'true muslim'. 'True muslim' tag is not 'universal'. Till today nobody can unambiguously/univocally/indisputably define 'true muslim/islam'. We have 100s of parties in Islam. Each party considers themselves as 'true muslims'. This confusion will never ever be cleared until end of this world. Even terrorist claim they are 'true muslims'.
So, please continue your good works sir. By good works I mean moral/ethical and socially beneficial works, which are independent of any religion. Good is good. Bad is bad. No need any religious tags/support for it.
Thanks for valuable suggestions,(positive and negative comments )
What a joke Rahim!!! From which jungle these so called politician are coming from... Redicolous
Only in front of Media he is telling that he is not accepting interest. The real matter is entirely different. If he is a true Muslim he never join facist party like BJP. If he take interest or leave interest what is the difference....??? for him.
Dear Raheem Bhai,
If you are a true muslim then you should not accept even 50,000/ rupees . Because it is not that your hard earned money. Being a true muslim atleast you should donate this money to some charitable organization such as Old home , disabled children center or orphanage , then only you can say you are a true muslim.
Ra(hi)m Uchila, you cannot be a true muslim by not accepting interest, you have to learn and practice Islam to be come Muslim.
example for the man kind, best of rahim uchila \Being a ‘true Muslim’ I cannot accept interest,” he said."
By the way, what was the actual allegation? Can you please publish that defamatory article here ? :p
Rahim uchil shirt color and pose super
Just avoiding interest will not make a person true Muslim. A Muslim has to set example by practicing all teachings of Islam in life, so that even Non-Muslim be attracted.
