The same goes for CoVid. These masks have been very little help, only if someone coughed or sneezed, but not with normal breathing. I prefer to carry a disposable tissue with me for these events, not wear a mask over my nose and mouth.
Where masks are useful is for virtue signaling and for control of the masses. They are very effective in that regard.
