CFR

CFR stands for Case Fatality Ratio, or maybe Rate. The denominator would be the proportion who we know got the disease, and are done with it. One way or another.

The number of cases should not be considered for CFR… at all. Many of those are ongoing. These, we do not know how will all end up. We use CFR alongside total cases to guess those still-living cases' outcome.

Here is how maximum CFR should be calculated: deaths / (full recovery + deaths). I say “maximum” because the “full recovery” variable is a minimum - here, because some "asymptomatics" are caught early, so may be presymptomatics. But some are lucky and go through it all just fine. I'm assuming that the statistics aren't lying about the deaths.

Once you're in the ICU, from what I understand, you're in trouble. That CFR is 30% going in, 70% on mechanical respiration. And that's not counting the morbidities that the machine adds to your account when you "survive". Our job is to stay out of the ICU.

Also, we need frequent and free testing. That requires different leadership than what we got in Trumpestan, and in all its little statelets passive-aggressively letting this play out. As far as different leaders, we'll see what alternatives we get.

UPDATE 5/15: Infection Fatality was 1% in April and prior. CFR is therefore greater than that - and that's where morbidity kicks in. A hospital stay [as of April] would boost this to 30%. But maybe this is better now.
