This sort of thing is why I believe business closures should only go statewide when 3/4 of counties in the state have evidence of community transmission. Of course, the state gov can feel free shut down businesses in individual affected counties, as far as I’m concerned, until the 3/4 threshold is reached (2/3 for RI and DE). OTOH, shutting down all the publik skrewels in the state is fine — kids in a school can spread this bug like wildfire, both to each other and to teachers, some of whom may live in another county.
Last I looked at the numbers we met your threshold sometime yesterday.
