Great points. It’s worth adding that SARS-COV-2 is spread primarily through the air via extremely tiny droplets (< 5 μm) [1]. Breathing, coughing, and sneezing produces infectious aerosols which can remain suspended in the air for hours. Most cloth masks that are used by the general public will provide very little protection against inhaling or producing these aerosols [2], though such masks are likely to help reduce the spread of larger droplets.
