“It is simply too late and there has been too much spread already”
I don’t think so. Or, I don’t sense it...
China showed regional quarantine helps when everything else is out of control. I suspect it is because people try to escape from dense hot zones with full hospitals...and carry vast quantities of the virus with them.
NYC is likely our first candidate in the US, if it ever comes to that.
The virus clearly spreads much more quickly in a dense urban environment.
I was ranting about Grand Central Station right at the beginning of this thing.
That one location probably is responsible for more positives than are in ten inland western states combined.
