Commonly used face masks, shields unable to prevent Covid-19 virus transmission: IIT BBS study – Times of India

BHUBANESWAR: In view of the second wave of Covid-19, everyone is focussing on carrying masks to minimise the unfold of the virus. But an IIT Bhubaneswar study has revealed that the generally used protecting measures like face masks and shields are unable to prevent the escape of droplets generated throughout respiratory.

The study acknowledged that leaked aerosol particles might include the virus, which can set off the airborne transmission of Covid-19 and different related ailments. The researchers recommended {that a} business 5-layered masks is noticed to be the simplest measure with minimal leakage of the droplets. This study has been chosen as a ‘Featured Article’ within the journal of the American Institute of Physics (AIP) Advances.

One of the 4 researchers, Venugopal Arumuru, assistant professor (faculty of mechanical sciences), IIT Bhubaneswar, stated the bulk of the earlier analysis works put emphasis on understanding droplet era and transport by coughing and sneezing. “However, ‘breathing’ the most common phenomenon, is scarcely studied as a virus transmission source,” stated the researcher within the study.

The researchers stated the smaller droplets (diameter

“A commercial N-95 mask completely impedes the leakage of the droplets in the forward direction. However, the leakage of droplets from the gaps between the mask and nose is observed to be significant. A five-layered mask is observed to be the most effective preservative measure with minimum leakage of the droplets,” stated the study.

The study acknowledged that there’s a want for innovation in face masks design, which might current the leakage of the droplets with sufficient human consolation. New tips want to be formulated for deciding the air circulation price in confined area contemplating the leakage of the aerosol particle from protecting measures,” stated the study.

RV Rajakumar, director of IIT Bhubaneswar, congratulated the crew for this study. “Apart from wearing masks, social distancing is very much important during this pandemic. Further research is needed on this study,” he added.
