I can see how they may become transmission corridors. My thought is they could also be treatment clusters. Don't just quarantine them in place, per se. Take over nearby hotels and spread them out, if needed. On contamination, have all supplies ready and onsite.

Note, I explicitly don't think this would be cheap. Such that I am not sure it is tenable without hindsight.

That said, I can see your point. With my firework shop metaphor, you are basically proposing to disperse the inventory such that one misfire will not ignite all of them.

I think I just have a hard time believing we will contain this with all of the other data we have seen. My gut is it is as likely that there is some yet unknown factor for the places that have seen better numbers.
