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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

U have been voted to develop ur area. Do that first. We muslims don't have any issues if your women's go to temple or not go to temple. It's ur internal matter. We don't interfere. Pls do not interfere in our matters. U have right to do whatever you want to do. We don't come there. So do good to your are in this 5 years and next time also u will get elected for your good deeds. I feel sorry for those who voted you. God bless India.
Ahlan Wa Sahlan welcome to all faith include prathap simha
If in case any muslim women tried to engter Sabarimala temple it is 100 percent her fault. As entry of women is not allowed in this temple, she should respect the rules and should not put herself in trouble. What is the need to her to enter in a restricted area. In case she believes Sabarimala as God, why is she represents as Muslim. None will stop her from follwoing Ayyappa religion as Islam or muslims will not lose anything if she ruins her present and future. As she has no respect to her own religion how can we expect her to respect other religions. she might be doing it to get publicity or she is bribed to do so.
My dear friend, none will stop entry of women of any religion in masjid, but they should pray separately. Many masjids have prayer room for women as they are not allowed to mix with males while praying. However, for your information, it is preferred to muslim women to pray in home and there is no force on them to go to masjid to pray. This is a facility provided to them and in case any woman wants to pray in masjid it is due to the nfluence and unnecesary advice of any person.
Dear ex bhakat, he is a member of kesari jihad organisation.
Yes All Women are welcome. Irrespective of Faiths.
Yes , all faiths are permitted to enter mosque .
E.g. Sheik Zayed Mosque , Abduhabi.UAE.
Please google it if am wrong.
Because u people are borries
Anyone can entre mosque. But women cannot mingle with men in mosque unlike in temples and churches. There will be separate place for men and women. Unfortunately, in India most of the mosques have no facility for women. But Prophet Muhammad (pbuh) warned men against preventing women’s entry into mosque.
What the hell you are asking sir? Are u promoting love jihad?
