I know I'm not an expert of any kind but I think this governor is miss understanding to some extent the reasoning for wearing a mask. The way I understand it is the majority of the function of the mask is NOT to prevent you from contacting the virus, but is to reduce the spread of the virus from the person wearing it. Say if you are a non-symptomatic carrier of covid the mask would help limit the area the virus spreads to when you exhale. There by limiting to some extent the chance you will pass it on to someone else. If someone has information saying it is more for acting as an incoming filter I would like to see that information.
