There are a lot of misconceptions about masks and how they stop the flu virus. Let's set it straight.
An ordinary paper mask will not stop you from catching the flu, only stop you from spreading it. If you already have the flu, then by all means wear
one; otherwise, you're wasting your time.
A N95 respirator mask will filter out particles of .3 microns or greater, which will stop water droplets from a sneeze or cough. This will not,
however, filter the virus if its already floating in the air, as the flu virus is about .1 to .12 microns in size.
In summation: If you have the flu, wear at least a paper mask. If you're in an area where the flu has been found, wear an N95 respirator mask, and
avoid places where the flu may be floating in the air, such as hospital emergency rooms.
