Commonly used face mask, unable to prevent Kovid-19 virus transmission: IIT BBS Study

BHUBANESWAR: Looking at the second wave of Kovid-19, everyone is focusing on wearing masks to reduce the spread of the virus. But an IIT Bhubaneswar study showed that commonly used protective measures such as face masks and shields are unable to prevent the exodus of droplets generated during breathing.

The study notes that leaked aerosol particles may contain the virus, which may trigger aerial transmissions of Kovid-19 and other similar diseases. Researchers suggested that a commercial five-layered mask with minimal droplet leakage is considered the most effective measure. This study has been selected as a ‘Featured Article’ in the Journal of the American Institute of Physics (AIP) Advance.

One of the four researchers, IIT Bhubaneswar assistant professor (school of mechanical sciences) Venugopal Arumaru, said that much of the previous research work emphasized understanding droplet generation and transport through coughing and sneezing. The researcher in the study stated, “However, the most common phenomenon is ‘breathing’, known as a virus transmission source.”

Researchers said that small drops (diameter)

“A commercial N-95 mask completely impedes the leakage of droplets in the forward direction. However, the leakage of droplets from the gap between the mask and the nose is considered significant. A five-layered mask is considered the most effective preservative measure with minimal leakage, “the study said.

The study stated that there is a need for innovation in face mask design, which can present droplet leakage with sufficient human comfort. The study noted that in view of leakage of aerosol particles from protective measures, new guidelines are needed to determine air circulation rate in confined spaces.

IIT Bhubaneswar Director RV Rajkumar congratulated the team for this study. “Apart from wearing masks, social distance is very important during this epidemic. There is a need for further research on this study, ”he said.
