A study published on the PNAS website on May 13, 2020 suggests that talking without protection can release thousands of micro-fine saliva drops per second from the mouth, which could not be seen with naked eyes because the drop size can be as small as less than 30 micrometers.

High viral loads of coronavirus 2 (SARS-CoV-2) that causes covid 19 have been detected in oral fluids of infected patients. The authors conclude that is highly likely that “normal speaking causes airborne virus transmission in confined environments.”

This study validates that wearing a face mask is a way to prevent the spread of the coronavirus 2 Sars-cov 2 virus.
