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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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
The 42-year-old Beary artiste-cum-politician, who had earlier served as the vice president of the Dakshina Kannada district unit of the Minority Morcha, will now also be in-charge of the minority unit of the saffron party in twin coastal districts of Dakshina Kannada and Udupi.

Please watch PK Movie, you will understand what does PK means... Cheddis alwz see Pakistan in their dream, its your fault for not using your mind to recognize the cheddi deception. Till when will you submit to the cheddi's lies and follow & support their evil agenda..
Use your intellect and be honest. We all clearly see their Lies and deception. Never think they will not be accountable...
DONT BE A WATCHMAN OF BJP AND RSS
Mr.Raheem, You have the right to join any political party. But please do not misquote Quran & Hadees for your benefit. i watched many debates in local channels , you were misquoted some ayath & Hadees about Go Hatya & Conversion. Political position is temporary but atleast show little bit ethics in your life. Do not justify Kalladka Bhat Hate speech /Soolibele about madrasa.
People are ready to release their families for their personal benefits. This guy doesnt even know what is Hajj Subsidy. He was claiming in one of his speech that \Muslim are receiving subsidy which was supported during AB Vajipaye govt time\" and muslims should support BJP. My dear, there is provision of subsidy to all religion if they are travelling abroad as pilgrim. Search it. Dont be so cheap to claim against own religion. Shame on you."
Dear brother Rahim uchil,
Congratulations for getting new responsibility. Hope to see some positive results this time from saffron party towards muslims. Take those comments as challenge and do something good for community. Hope to see you in more and more good positions. Wish you all the best.
Rahim, Uchila, you give answer in Mashara OR jahannam.....who bothers ???? your answer proves that you do not have guts to face the people........ Some one compared you to abbas naqvi and shanawaz hussain...... they married to young Hindu women .
If possible, do one more thing, work for the cancellation of Haj Subsidy..... Owaisi is struggling to put this in Modis Bheja, but it is not going.... try your best and tell the Muslims, that Allah do not need the haj from us with the begging from Indian govt.
Congratulations brother.
Masha Allah. Congrats Rahim Uchil. You are doing good job. BJP is far better than Congress and Rahim Uchil is far better than all Congress leaders from the coastal. He is a pious Muslim and a die hard fan of internationally acclaimed scholar Shaikh AP Abubakar Musliyar.
My message to Rahim sir: Dont care wahhabis and salafis. Our prophet has said muslims will be divided into 73 sects and only one will enter jannah. Who knows that sect might be the one which is with BJP!
Good answer brother Rahim Uchil. Dont care about jealousy people. We are all with you. In fact this news portal has more Wahhabi commentors. Just dont care them. Let them keep blaming. As Rohan sir rightly said, you may one day become a minister. Then those who are blaming you now, will be at ur threshold for your permission to bring their zakir naik to mangaluru. hahaha.
Bjp and RSS is behind minorities and daliths, they are doing every efforts to curb these two relegion. Their paid servants are asking our leaders head for lacs of rupees. So any one who go behind these RSS is not our men. He is against our relegion and against us.
I really dont understand why some people are so much narrow minded. he has given some responsibility. Muslims must congratulate him and try to take maximum benefits from his position. Who knows after next election he may also become a minister.
Anyways. All the best Mr Uchil. Go ahead and do good for the society and also for your community.
Just reward for defending communal news paper which published article against Islam and our prophet. He losing religion/people for Duniya's political career.
Mr PK (Comment No.8)
Your name also suggests that u r a pakistani fan. by the way Mr Rahim Uchil is appointed as BJP Minority Morcha vice president. And you are advising him to do the works of Mukri Morcha vice president! thats very funny!
Dear raheem uchil, may allah guide you to understand islam...aameen
Before answering to all the above questions you need to prepare yourself here in this world.
Congrats Rahim Bhai. You are one of a very few nationalist Muslim. We are all proud of you. Hope you will change the fate of ur community and teach them nationalism.
His life style fits into BJP which is built on corrupt foundation. The man never hesitates to do anything crime for personal benefits. This is the quality against the Islamic values.
EFFECT OF DIGITAL INDIAAAA.....

Govts are not permanent, tomorrow it may be out of power.. People already know now who is a leader and who is a deciever.. Y dont YOU recognize it?
Another Naqvi or Shanwaz he too will be fit in nothing
Poor Chap what a pity.
I will give answers in mahshara.. In sha Allah
Clearly Cheddis are barking against Muslims and Dalits... and this Cheddi chela blind to see it...
Cheddis are very cunning in deceiving the people including their own cheddi members.
U have already become a weapon for cheddis to fight our own BROTHERS in faith.
They use dalit members to attack innocent which we now know .... whats their fate (Some spending their life in prison and some are on the run to the courts and some even in hideouts)
Only ALLAH knows Whats your intention by joining the haters of Muslims who opening deceive public about the peaceful religion.
Head Master of the school where there is only one master in the entire school.
Congrats Rahim Yachil, Engage Praising R.S.S an BD Goons acts and following kalladka Bhat, you will be prosperous future in National level.

BJP needs such muslims who are ready to sell themselves for the sake of money and seat though their own people are suffering from this hate mongers of BJP.
I hope this man was there in the sangh parivar processions who attacked Muslims and ransacked their propertities plus places of worship.
Dear Rahim, i could not understand what will be your fate on the Day of Judgement for your injustice to your own people You are supporting the terrorists who are after Muslims. shame on you.
