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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

its like every month ONE SWAMI is caught for sexual activities..
ALL above big Swamis caught in this act... When will U guys WAKE up... Hindus need to understand and not fall trap to anybody...
JUst depend on GOD. To depend on GOD only, U need to learn WHO is GOD... IF U are HONEST, the GOD who created U & ME & all that EXISTS will GUIDE YOU...
STOP worry about your life with all the RAHU KALAAS and other KALASS its a game played with the one who is far from the TRUE CREATOR... When U recognize the TRUE CREATOR ... U will understand this JOYTHIS Deception like \this day is not good or that\"
STOP fearing... and LEARN who is TRUE GOD."
Idol worship is wrong and the people who run it will never say to YOU guys cos its a money making tool to fool those who doesnt look \WHO is their CREATOR\"
Unless U search for YOUR CREATOR of YOU and all that Exists... We all fall to such a way of deception in worship which make the creation like STONES as YOUR GOD or REACHING GOD (which seems that we are not using our god given intellect.)
The CREATOR says PONDER on ME ... He will Guide us ..But If we rely on IDOLs and other created objects as Gods then our Intellect is ZERO. NOTHING
God says HUMANs are Intellect than any of his CREATION, if we USE our Intellect... to HONESTLY look for HIM. He will Guide us. even if you are in deep jungle looking for HIM.
But people believe what is said and they doesnt use their intellect. which is pushing them FAR from the TRUE CREATOR.
Recognize YOUR lord and WORSHIP the CREATOR and not his CREATION... U will not fall to such pornist as your SWAMI. its not first ... U check your self... (NA TASYA PRATIMA ASTI) There is no image of God ... PONDER Y are U asking with the ImAGE which is LIFELESS>>> not even move hands and heads like us."
Dear Brothers,
Please learn from these endless incidents.
Hindu community is responsible for these incidences not only the Babas.
This is the consequences of Not allowing the priests to get marry.
the same thing happens with Christian churches.
Allow the priests to get married. As they would have families, they can understand the problem of worshippers, public
Otherwise you have to face the unfortunate consequences with our own sisters.
May God Guide
BOLO BABA PARAMANAND KI...
Now many might be dreaming to became SWAMI at-least once in life time to have free fun and enjoyment with support and protection of RSS/BJP goondas and politicians
LOL..!! The continuous news of HindusSanghis involved in rapes, molestation etc. and in return the reward to set them free, one can simply say- Bharat Mata ki Jai!
LOL>>>We are not saying ALL HINDUS ARE RAPISTS. BUT ALL RAPISITS ARE HINUDS.
Doesn't it sound similar to Terrorist/Muslim etc.
Parmanand ji Maharaj: We are all fortunate to have Narendra Modi and Baba Ramdev with us.
Baba Ramdev is out of depth now. My sincere advice with Swami Parmanand jee is do Dhyan for sometime to regain balance.
Baba Hari Das gave me the name \Parmanand\". I think it was a great joke because everyone started calling me \"Parmasean\"."
Seriously i dont know, who make them famous, why people go there..
Baba Parmanand is a \stud\". Literally Was sexually exploiting infertile women to.. A feat at his age."
Just look at sanskaari, oops I mean, tharki Baba Parmanand's age. But then I am probably being ageist!
There goes another Fake Godman.
