Another interesting way to look at the local covid-19 stats for San Mateo County CA is the death rate by age. This virus is showing a dramatically different lethality by age bracket. I know there are researchers looking into this and there is a lot of data about comorbidities, but I don’t know for sure if age is simply a very good proxy for comorbidity.
What this chart tells me is that we HAVE to get this virus under control for the long term. If these death rates stay constant, then after a few years there just won’t be many people left over 70 years old.
