Read my comment #1 that says what we been told about masks.
Also from CDC
CDC recommends that people wear a cloth face covering to cover their nose and mouth in the community setting. This is to protect people around you if you are infected but do not have symptoms.

Yup, a mask won’t do diddly to prevent a person from getting the virus. The reason the powers that be give to wearing are to stop a person from spreading it, the idea being that it “captures” a sneeze or cough to some degree. Otherwise, as even Fauci says, it’s just symbolic - like wearing a ribbon for whatever cause.
