Fun story, a total of 12 people wore masks in town (required for their jobs), everyone was fine. Then a cold snap came through and oops, because of schools getting everyone tested and then all families getting tested a ton of people tested positive. So for two weeks of everyone being contagious we went about our business in masks. Two weeks was up and no more masks, we're all still fine lol. So yeah, in my area if someone is wearing a mask there is a good chance they have it.
