Are there abnormally high numbers of store cashiers, bar tenders, restaurant wait staff, teachers, ect. that are testing positive? I did a real quick google and all I found was where COVID "could" be highly transmissible based on conditions but no hard data. I would think it would be rather easy to compile this information and would give us a good sense of the type of situations and environments where COVID is spreading. Remember when grocery store workers were considered "front line workers" back in spring - I don't remember hearing about massive amounts of them getting COVID. Three weeks ago a H.S. classmate of mine died from COVID (age 54, Dane County). She was a bartender, a second job to acquire some spending cash. Will never know if she caught it from a patron, but plausible. So it does happen.
