> you walk by a group of people in the park and they’re infected >This has never been documented in the entire history of SARS-CoV2 This seems like something at risk of being a self fulfilling prophecy. How would something like that be documented? You can't do contact tracing on random people you walk past in the park. Even the contact tracing apps, sparsely used as they are, generally require a 15 minute contact period to "count". We've assumed that it can't happen, but we have no way of knowing if it did happen. (Anecdata, accompany with 0.36g sodium chloride: I was speaking to someone over the weekend who claims they can pinpoint to a 20-minute window when they got infected (on the basis that they could not have caught it from anyone else that day) and they reckon that they got it from walking down an extremely densely crowded alleyway. Due to a testing screwup, this person isn't even documented as having had Covid at all. Of course, they may be mistaken, but nevertheless it goes to show that just because something happened, doesn't mean it will be recorded.)
