<span style="color: #222222;">IIT Bombay’s researchers have proved that, if appropriate social distancing is not maintained then the Covid -19 infection may probably double up. And hence the use of face mask and maintaining social distance are always advised as important scientific guards against COVID-19.<br />” <br />” AIR correspondent reports that IT Bombay’s researchers Prof. Amit Agarwal and Prof. Rajneesh Bhardwaj have first time quantified the probability of infection for a super-spreader. As per their research findings, Super-spreader emits infections more than 3 times as compared to a normal person. The surgical mask reduces the chance of infection to about one-third of the no-mask while the N-95 reduces the probability of infection to a negligible value.<br />” <br />” The research paper further says that the Probability of infection increases by up to 185 % if appropriate social distancing is not maintained. Research says, The presence of a mask drastically reduces the volume of infected air and significantly cuts down the risk of the infection to the other persons present in the room.<br />” <br />” They also say that coughing into the elbow and the use of a handkerchief, can reduce the volume of a cough cloud and, therefore, the chances of dispersion of the virus.<br />” <br />”This research paper will be soon published in ‘Physics of Fluids’ journal published by 'American Institute of Physics'.</span>
