I dont say its all coincidence I just say its not all from rehearsal either.
I just found the headline sensationalistic in that sense.
They were in a hot spot and high risk. So they could have gotten it lots of places around town.
But Skagit County hadnt reported any cases, schools and businesses remained open, and prohibitions on large gatherings had yet to be announced.
They were not in a high risk area. There were no cases reported at the time in that area.
My pathology professor gave me good advice decades ago. When you hear hoof beats think horses not zebras. I am concerned that you are trying to cobble together a case for something that is mathematically impossible to avoid looking at the most probable truth.
Ten cases I could see as possible, even though in NJ, which actually is a hotbed with 22k cases and 355 deaths, few people have more than 1-2 acquaintances that have been diagnosed with COVID-19. 45 out of 60, impossible.
I would not care that you were pursuing a zebra so assiduously if there was no downside but this incident is the most extensive transmission of the virus within a group, seen to this point in America. There is something unique about this incident and we need to be armed with the knowledge of what that might be. The choir would have been breathing in deeply & expelling with force. Prudent people should not ignore the likelihood of enhanced risk of spread in similar circumstance.
