>where it’s possible that 80% of people have had the virus,
If a demographically representative cross section of the population is infected, I would operate under the assumption that about 0.9% of them will die. From what you write about NY city, it sounds like you think the fatality rate might be a lot lower. I think this will be a major crux for people and so I’d focus first on addressing questions like why recent serology surveys in NYC grocery stroes find only 21% of people with antibodies.
