Note to that enemediot: Using a disposable facemask to protect against an airborne respiratory virus is like using chicken wire to keep out mosquitos.
IMPORTANCE Airborne simulation experiments showed that cotton masks, surgical masks, and N95 masks provide some protection from the transmission of infective SARS-CoV-2 droplets/aerosols; however, medical masks (surgical masks and even N95 masks) could not completely block the transmission of virus droplets/aerosols even when sealed.
