“We know that wearing a mask outside health care facilities offers little, if any, protection from infection,” according to an article published in The New England Journal of Medicine, written by researchers from the Harvard Medical School, Brigham and Women’s Hospital, and Infection Control Unit and Division of Infectious Diseases, Massachusetts General Hospital in Boston, Massachusetts.

 

They go on to write:

“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.”
