The word ‘social-distancing‘ is often heard as the only remedy that could prevent Coronavirus spread. It is the only way to stop the community-spreading until the Vaccine is developed. We are told that Six feet distance is mandatory to keep us safe from respiratory droplets that pass the virus.
Lydia Bourouiba, an associate professor at MIT, has researched the dynamics of exhalations (coughs and sneezes, for instance) for years at The Fluid Dynamics of Disease Transmission Laboratory. He disagrees with the Six feet formula and says it is just not enough.
He claims that his research found exhalations cause gaseous clouds that can travel up to 27 feet. WHO and Centers for Disease Control (CDC) should immediately revise the guidelines about the Social-Distancing, he says. In such a case, we are already dead.
On the other side, the total number of cases across the globe crossed 800,000. The first Four Lakh cases were recorded in four months while the next four lakh cases took just One week.
