If I can add - Do not bother wearing a face mask unless you are actually sick! The people who need them for avoiding contracting the illness are the medical staff treating those infected - Distancing & hand washing is much more effective than masks for the currently not sick. The virus can also enter via the nose and eyes, and is not airborne apart from in the coughs of an infected person, so unless you are letting people cough on your face while out in public, a mask is going to do no good.
Don't hoard them as that deprives the medical personnel who need them most of the supplies to keep them safe.
If you are showing symptoms, then there is potential benefit to others around you from wearing a mask - but you should be in isolation if you are showing symptoms anyway so it's a bit of a moot point.
Stay safe all otherwise though
