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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

All these because of lacking of knowledge of fundamentals of Islam.
Islam is perfectly taught with boundaries for what to be done and what not to be done.
What to be done are : Farz, or obligatory deeds
What may be done : N compulsion, but doing can lead for extra reward
Not to be done Prohibitions : These should not be done. Like Associating someone with the True God who created us who only deserves to be worshipped. This is a biggest crime in Islamic point of view. Other prohibitions are eating pork, liquors, adultery, gambling,
Now the things what happening mostly in Dargah are worshipping the graves, which is the biggest crime. This is forbidden to both men and women. People can visit the dargah and pray for the dead people in that grave. But begging the dead there is prohibited.
Really those dead bodies can not help us, in contrary those bodies need prayers, wishes of living people.
We can visit the dargah in the intention to pray for the dead in the grave and to say Salam. Doing like this properly is not sin.
Wrongly Visiting Dargah can mislead to sin,
And not visiting Dargah does not amount to sin.
Therefore people lack basic teaching of Islam.
A MUSLIMAH ( True Muslim Women) will never ask with any other creation EXCEPT ALLAH... Those who depend on other than ALLAH will get what they want but in the end they will fall for the trap of deceivers who are attracting the people who are WEAK in IMAN to their way of worshiping the graves or asking with the graves.
THOSE who have faith in ALLAH will never ask or depend on, other than ALLAH. They are Satisfied with what ALLAH gave and Say ALHAMDULLILLAH in whatever situation comes their way... Congrats to such MUSLIMS and MUSlIMAH who trust ALLAH and follow the teaching of Prophet Muhammad pbuh... who never showed us Such CULTURE of DARGAH ViSIT..
Prophet MUHAMMED pbuh said... Visit GRAVES to Pray for the one who is in the GRAVE & REMEMBER that one day our fate will be same. So dont live in this life in ARROGANT or do injustice to Others.
Dear Sahil, if they knows the meaning of Namaz or Salah they never visit Dargah. Here may be RSS behind such kind of demands.
These so called muslim women don't know Islam. so they are asking entry to Dargah/Grave yard. Who stop them to go there go and enjoy.CD Editor please remove Muslim woman tag because muslim women never ask such kind of demands.Better tag Ahle biddah women ask entry to darga.
They dont bother about namaz..but worried about entry to do shirq
Haha..funny..they dont bother about performing namaz..
But worried about entry to dargah to do shirq..
Dear CD team. Please be careful when you posting one sided opinion about practice of Islam. You have reader from all sections.
REALLY SURPRISED TO SEEE THESE MUSLIM LADIES IN ROAD PROTESTING FOR ENTERING THE DARGAH ,
FIRST THEY HAVE TO OFFER NAMAZ PERFECTLY I DONT KNOW WHAT THEY WILL GET IN DARGAH ....
THEY JUST VISIT TO ASK TO THEM.. THATS NOT GOOD WE HAVE TO ASK WITH ALLAH HE IS OUR ALL MIGHTY ..
