“Why do we see every healthy healthcare worker wearing a mask?”
They have fitted masks and know not to pick their nose.
Except for those in full respirator gear, the ones I see have masks of the type that the wearer fits to their face (or perhaps with help). If masks help when properly fitted, that’s what the official guideline should say.
Seems wearing a mask will stop people from picking their noses.
I have family member that gets masks at work...They are checked to make sure using the correct size for proper fit, but not specially fitted.
Ah, geez. You mean not to pick one's own nose?
I've been doing it all wrong.
