There’s no actual rule in NYC against going outside, though, and people are still going outside. Parks are still open.
Maybe thankfully, the virus is still spreading, albeit more slowly and petering out. Mass testing in NYC now shows about 25% of people exposed from 3-4 weeks ago (due to delays in development of antibodies). Error bound is probably +- 5%, so 20-30%. Hopefully, we’ll see 50% or more immunity in the next month — at that point, the thing will have difficults finding non-immune hosts with even basic hygiene measures.
Cuomo isn’t talking about herd immunity explicitly, but is de facto, since he’s said that 40 to 80% of people will get this, and he wants to keep reproductive number between 0.8 and 1.2 (linear spread).
My problem with what the state has done is that they haven’t done enough to protect the truly vulnerable. Thousands (up to 5000) of the deaths in NY have been in nursing homes. A state policy in March required hospitals to discharge COVID + patients back to nursing homes. This kind of policy is criminal, and I hope the people responsible for it stand trial.
