MOSCOW, Dec 10 - RIA Novosti. Japanese scientists from Fukuoka University have found that commonly used face shields do not protect against airborne transmission of coronavirus. The results of their research are published in the journal Physics of Fluids.

Experts analyzed the movement of air currents around the shield, which occur when an infected person sneezes next to him without a mask.

It was found that sneezing or coughing creates vortex rings that gradually become unstable and deformed in three dimensions. At the same time, reaching the upper and lower edges of the flap, they fall under the screen.

If the period of inhalation of a person who is opposite the sneezing coincides with the ingress of a vortex ring into the flap, then he will inevitably inhale infected particles, the researchers emphasize.

Scientists are now working to improve personal protective equipment, trying to reduce the risk of inhaling particles from air currents entering the screens.
