A commercial five-layered mask coupled with social distancing and good ventilation may be key to curtail the spread of SARS-CoV-2, the virus that causes Covid-19, in enclosed spaces like offices, prisons and hospitals, say researchers from the Indian Institute of Technology Bhubaneswar, Odisha.
The findings, published in the journal AIP Advances, showed that just breathing or participating in normal conversation, even without the risk of coughing or sneezing, led to a leakage of air droplets from masks. While a commercial five-layered mask showed full front-of-face protection and minimal leakage below the chin, N-95 masks showed leakage in gaps between the mask and nose. The surgical mask also showed leakage from the front.
