New York is just ideal for a massive outbreak - density, climate in spring, late response. It’s basically Wuhan but worse.
Wuhan shut the city down, but not before about five million left town (Wuhan is a regional hub but must of the residents aren’t from there so are quick to leave - or may have even been going home already for the (lunar) new year). The pre-lockdown exodus exported the virus but also cut down Wuhan’s density.
Is it going to get to the point where people start bailing en masse on New York? Will a more vigorous lockdown prompt a similar exodus?
