NYC Peak on the chart here, down a bit, latest data likely higher as delay. https://www1.nyc.gov/site/doh/covid/covid-19-data.page
So far, the biggest damage to the economy was done by the state governors and federal government bureaucrats, not the virus. In my state they keep cannabis stores open - those are essential.
Only around 10% of Italians have antibodies/have been infected. https://www.thetimes.co.uk/article/coronavirus-only-10-of-italians-have-antibodies-xf7rfxlcq Applying same ratios to New York city, that would mean around 25% of NYC has been infected so far. 2 million people in the City of 8 million.
I read the story on Daily Mail as the Times has a paywall. On one hand the health official doesn´t explain how they came up with that 10% number, the antibody tests haven´t been applied yet in Italy at least on a significant scale according to the article. Besides 10% of Italy´s population is 6.3 million people, compare that to the 175000 registered cases there and 23200 deaths. That would put the mortality rate of the virus @0.37% in a country which Health System has been apparently overwhelmed
How many of those 6.3million are still going to die? That will get the death rate from 0.37% to at least 0.5%.
The 10% number seems to be much of a guess, and so is our discussion about it. That would depend what antibodies we are talking about, it seems they try to test 2 different kinds of antibodies, ones that exist once a person is still fighting the disease, and others that show up once the virus has disappeared or at least is considered non agressive and non contagious. It makes sense the immunity passport is only considered for those in the second group.
They are ballpark numbers. But I think all the data does clearly indicate that no city of country is anywhere near herd immunity. New York City might be closest at 2 million infected out of 8 million people, 25% (if i had to give a ballpark number)
