This is from the New England Journal of Medicine on May 21, 2020:
We know that wearing a mask outside health care facilities offers little, if any, protection from infection.
Public health authorities define a significant exposure to Covid-19 as face-to-face contact within 6 feet with a patient with symptomatic Covid-19 that is sustained for at least a few minutes (and some say more than 10 minutes or even 30 minutes).
The chance of catching Covid-19 from a passing interaction in a public space is therefore minimal.
PURE MAGICK AIN’T IT ?
