When it comes to NY, the run rate of recorded US daily CV fatalities has actually dropped - net of NY state. The only reason the US looks like it's still increasing is because of NY state. And NYC is the driver behind NY state.
The world might be beginning to realize that CV is in fact a highly regionalized type of natural disaster, really not much different than an earthquake, hurricane, etc. That means the resources of entire nations can be directed to targeted zones to attack the point(s) of incursion.
In the case of NY, the US can fly in additional medical personnel, mobile ICU units, etc. It also means the rest of the country can go back to business, with added stipulations with respect to social distancing, etc, while keeping close tabs on potential/emerging hot spots.
The history of this disease has been rather clear.
First it is just a Chinese problem.
Then it is just an Italy problem.
Now it is just a metro NYC problem.
hmmmm......
