There was a small testing regime in a Northern Italian town that was in the papers yesterday. They tested a whole town and by the end of it there had been no new cases at all when all around the virus rages. They found several asymptomatic cases.It’s still the case fataility rate tho.
and as I keep pointing out. In China the WHO looked for the iceberg assuming the known cases were the tip, they didn’t find it. So this is the calculation they are using to calculate mortality rate.
We'll find out the extent of it when the antibody test comes in.
Fatality rate (deaths / total known cases) in South Korea is low (1%). There they did loads of testing. I think it must be under 1% because you can miss cases but you're less likely to miss deaths.
