Well I witnessed it.
As for going to the hospital on your own, they were giving advice to please call an ambulance for Covid-19 suspicion. They DIDN'T want Covid-19 spread to the hospital and sick people in the emergency ward. So there was activism here to call 911 to get instructions which usually resulted in the ambulance
Also many people who said they could make it themselves to the hospital were simply told to stay home (again for fear of spreading it to others) and also because if you didn't need hospitalization, there was no treatment or cure for it. (" Yep, you got Coronavirus. Go home. We can't help you if you are well enough to travel. What do you want us to do? Two weeks quarantine but if your conditions worsen then call 911").
So basically the ambulance was sent for whenever someone was deathly ill.
At it's peak we were seeing over 900 people dying a day. That's dying, not hospitalizations. I suppose if the 2% death rate is correct you can extrapolate some larger percentage of Ill rushed to the hospital
Finally, PLEASE NOTE:. NY is STILL in lockdown!!! Broadway is still shuttered. Casinos closed. Movie theaters closed. Malls closed. A phased reopening is slowly underway.
It's law that masks must be worn. I would say about 90% of people obey this. The others get yelled at for their insolence and DON'T get served at most businesses.
You think we would still be in lockdown at this very moment if we didn't just go through hell?
