Mouth and nose masks are said to reduce the risk of coronavirus droplet transmission. But this (difficult to prevent) thing makes wearing it less safe
Wearing a mouth and nose mask is compulsory in many places in shops and on public transport to prevent the uncontrolled spread of the coronavirus. We already have over here common mask mistakes cleared up, but there is one more thing that makes wearing the mouth and nose mask less safe. Namely cough!
For one study, which was carried out by researchers from the University of Nicosia in Cyprus, various computer models were created to show how far droplets can be expelled through masks when coughing. It turned out that even with a slight cough, the pent-up air pressure is so high that the droplets can also be transferred over the mask – over a distance of up to one meter.
“Although masks reduce droplet transmission, they do not completely prevent the transmission of droplets in the air. Therefore, staying clear remains one of the most important rules in the fight against the pandemic,” the scientists conclude.
