Double Your Pleasure, Double Your Fun, Double Your Protection

Yes, if everyone uses masking properly, everyone is safer and better-protected. Double your fun!

Although the Centers for Disease Control (CDC) report does not provide very clear guidance, a careful reading of the NPR story and the CDC report may help the reader improve their masking methods. Note that although the CDC recommends cloth masks, current information favors the use of medical procedure masks and/or double masking, with a cloth mask serving to close gaps. And the KN95 masks are also good. If everyone in the community uses these good masking methods, the chances for transmission are reduced and everyone can be safer, according to the CDC.

Maximizing Fit for Cloth and Medical Procedure Masks to Improve Performance and Reduce SARS-CoV-2 Transmission and Exposure, 2021 (CDC report)

"SARS-CoV-2 infection is transmitted predominately by respiratory droplets generated when people cough, sneeze, sing, talk, or breathe. CDC recommends community use of masks, specifically non-valved multi-layer cloth masks, to prevent transmission of SARS-CoV-2. Masks are primarily intended to reduce the emission of virus-laden droplets (“source control”), which is especially relevant for asymptomatic or presymptomatic infected wearers who feel well and may be unaware of their infectiousness to others, and who are estimated to account for more than 50% of transmissions. Masks also help reduce inhalation of these droplets by the wearer (“filtration for personal protection”). The community benefit of masking for SARS-CoV-2 control is due to the combination of these effects; individual prevention benefit increases with increasing numbers of people using masks consistently and correctly."--- Scientific Brief: Community Use of Cloth Masks to Control the Spread of SARS-CoV-2
