It is interesting just why NY was hit with such a tragic tsunami.

I wonder how late they were in cancelling sporting events or pop concerts with large attendances.
A densely packed mass crowd who are maybe shouting or singing is the perfect cauldron for virus transmission.
As indeed is a crowded subway train.
Plus Broadway, of course.
Plus lots of incoming international air travellers into NY.

When and wherever social distancing was introduced, infections continued but at a a reduced rate.
Plus (and it's really only my hypothesis) you can get infected with the virus, but only with a small infection. (Maybe when you use a cash till and pick up a low level infection from using the keypad)
In other words, a small viral load.
(Very different to someone shouting in your ear at the Aqueduct racetrack, for example.)
And if your immune system is effective enough to handle a small viral load, you will be OK, and if you're young enough you will have minimal or no symptoms, but you will develop antibodies.
(Which is basically the principal behind many vaccines, where you receive an attenuated dose of the pathogen.)
Social distancing measures perhaps led to most new infections becoming mild ones because of low viral load.

And indeed use of masks was a very sensible idea from the outset.
But WHO advised against the general public using them.
As did the BBC in the UK...

I also think that maybe the virus is simply losing virulence over time.
