I would like to add one thing to the previous post.
I believe that wearing a mask does nothing to protect anyone, unless you are less
than 10+- inches from someone and face to face.
Then it makes sense if you are a Doctor or caregiver and very close to a person especially
if they are sick with any raspatory disease
If in an enclosed area with people close together who are strangers it makes sense to wear
a mask if or when there is flu or colds "going" around.
That's my opinion.
