Wrong article.
The virus is submicron, yes, but spewing coughing sneezing lickspittle saliva stews are hundreds of microns.
PS , I do this type of work for a living.
Then as you must surely know, "[c]oughing sneezing lickspittle saliva stews" are better controlled with a handkerchief than with an ill-fitting, improperly worn and maintained identity-hiding face mask.
Better still, if you're discharging "[c]oughing sneezing lickspittle saliva stews" your ass better stay home until you are well ... wouldn't you agree? Cheers!
Why are sneezing coughing people even out in public?
These essentially useless face coverings give them permission.
so you stop some droplets with a mask (the ones that dont go above below or out the sides). You do the same by covering your cough or sneeze. Think about those cloth masks everyone is wearing. unless they are discarded or washed after every use they are breeding grounds of disease living in your pocket or on your dashboard or in your purse. They are almost never worn or fit correctly. They induce the wearer to touch their face more not less. They probably spread more disease than they prevent
I remove the employer mandated mask to sneeze into my elbow. I cant imagine not doing so.
