Masking up against COVID-19

Edited to add in January 2022: There is no longer a shortage of medical grade N95 masks in the US as we had at the start of this pandemic in 2020 (see next), but, sadly many are reticent (hesitant) to wear them still. Also, KN95’s and K94s are 95 and 94% effective, whence their names.
