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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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
According to the reports, Shahnawaz, a resident of Uttar Pradesh's Saharanpur district, about 500 km from here, called his wife a few days ago and pronounced the word talaq' thrice and severed all relations with her.

He is a crazy without having any knowledge of islam. He only knows Talaq but does not know how to implement or follow it. such people are bringing shame to muslims and Islam. He should apologise for this great mistake and ask for pardon from Allah. May Allah give him right knowledge of Islam.

I don't understand why non Muslims are more interested then Muslims to discuss about this subject. Mind your own business guys....don't disturb Muslims...they know what is good for them....
Very bad ...women are considered as property and I met one divorcee but well educated ..her husband left her just becoz she had baby girl ..he is roaming freely in India and she was in trauma ...later one good hearted married her ..of course he is a Hindu ...now they stay in Singapore only ...to send sexual abuse and polygamy ..govt must bring strong rules ....
Request everyone to watch video on triple talaq by Br.Imran. https://www.youtube.com/watch?v=MwNAgNNE-lI
This is an ignorant act to Claim a divorce, Divorce, in Islam is the most uncalled act for any man or women. The conditions and procedures are highly thoughtful & very clearly mentioned in Quran. A short example of one of the conditions: A triple Talaq doesnt mean reciting the word thrice & done, but, Giving a waiting period of 1 month to resolute and try to improve in between each claim of Talaq.
I would wish the commentators here just go through what the Quran says from the right source and understand the integrity of Justice given to both gender. This holds good for generations that's passed and for future to come.
When such incidents happens..
its a way Non Muslims & Some ignorant Muslims will know the reality of the divine law.
We Muslims know that Devils are most happy when couple part...
So a true Muslims will try to stay together as much as they can save their marriage form splitting each other.. and There is an option for the couple who could not go along with the partner.. (For eg : if the husband is dunkard and wife have a chance to give khula (talaq) or if the wife is dunkard and husband can have the option of giving talaq despite several warnings to quit the habit)
WE see compared to other religions, Muslim divorce rate is very less...
I would request the Non Muslims and the ignorant muslims who misuse this divine law to look the answers from the source or please check below video
\Br.imran Answering About Triple Talaq To a Non Muslim Sister\"
Well EXPLAINED .."
I don't know why the other part of women's right in Islam is not highlighted to public....they forgot how sita was left back in the jungle with luv and kush....can we know the reason please.......
If there is rift between couples, if every ways of compromise failed to unite them... is there any other solution other than divorce ? whether he proclaimed thru phone or writing letter or any other valid means , discussion on 'way of talaq' is second option.. discussion on 'condition of couple's relationship' should be first option for discussion...
