We understand it daily, a key advice to slow the spread of coronavirus: to maintain six feet of social distance from other people. Public places such as shops and banks have marked the distance on the floor so that people are standing safely. But just as it has become a way of life, some researchers say that the distance may not always be sufficient to protect people against Covid-19.

In a new report, researchers ofMIT and the Oxford University are taking other factors - including ventilation, the size of the crowd, the duration of exposure and if facial masks are used - should also be taken into account when setting guidelines social distancing.

"It's not just six feet, then everything else can be ignored, or just a mask and everything else can be ignored, or just ventilation and everything else can be ignored" Lydia Bourrouiba, Associate Professor of Civil Engineering and environmental to MIT and CO -Author of the report, told NBC News. Read reading to decide when you should be tested and to protect yourself and protect your other during this pandemic, do not miss this essential list of theWithout signs that you have already had coronavirus.

Sing or talk can spread the virus more than six feet

Covid-19 propagates mainly through the respiratory droplets, the spray that comes out of your mouth and your nose when you sneeze or if you touch.

The researchers say that the six-foot recommendation is based on a science of eighty years, about 1948, how much the droplets can travel before falling on the ground. "Rules that stipulate a specific physical distance (1 or 2 meters) between individuals to reduce the transmission of SARS-COV-2, the Covid-19 causing virus, based on an obsolete dichotomous concept of the size of the respiratory droplets, "wrote the researchers in the report, which was published Tuesday inBmj.

Instead, there is evidence thatCoronavirus can travel more than six feet through activities such as expiration, coughing, singing and shouting, has declared researchers. In addition, there are risk notes. In high-risk situations, such as poorly ventilated rooms, large crowds, long durations, and no facial mask - a safe distance will not have to expand beyond six feet.

In addition, back in the day, scientists thought that the droplets existed mainly two sizes: big and small. The large droplets fall (hence their name) while smaller droplets (called aerosols) can linger in the air. We now know that there is a range of droplet sizes and how far they travel depends on the flow of air and expiration.

Experts such as Mr. Anthony Fauci, say that coronavirus is spreading through aerosolization and research are underway to calculate this risk factor. These results could redefine the six-foot rule.

Social distance based on a range of situations

In the meantime, theBmj The researchers suggest that we take a more nuanced vision of social distancing, setting guidelines based on a range of situations, low risk at high risk. They created aTraffic style toolTo help identify this risk based on activity, ventilation level, contact time and use of the facial mask.

Scientists have also urged more research on how the airflow diffuses the virus, which is the duration of exposure leads to an infection and size of the droplets resulting from various physical activities.
