Sure. Per yesterday's paper, there have been 15185 cases and 834 deaths in WA. That would be a CFR of about 5%.
Now, it says the cases are 33% above sixty, and the deaths are 91% above sixty. So that would be a CFR of 758/5011, 15%.
Contrast with below sixty. Which comes to a CFR of about .7%.
If I go with just under twenty, the paper doesn't give me enough data to calculate. They are 4% of the cases, but don't even get listed in the deaths breakdown.
Under forty, the rate is about 1.5%.
And note that more testing can drive down these numbers. But it's unlikely to do so for the elderly.
