Case fatality rate, also called case fatality ratio, in epidemiology, the proportion of people who die from a specified disease among all individuals diagnosed with the disease over a certain period of time.
Case fatality rates are not constant; they can vary between populations and over time, depending on the interplay between the causative agent of disease, the host, and the environment as well as available treatments and quality of patient care.
So, um... yes.
I read dang goodly!
“...case fatality ratio, in epidemiology, the proportion of people who die from a specified disease among ALL individuals DIAGNOSED with the disease over a certain period of time.”
Nowhere are the “non-recovered” eliminated, as you do. You can make your own name for your own math, that’s fine, be creative, but your formula is not the CFR formula
Well, maybe a term other than Case Fatality Rate (which formally has an understood meaning of cases/deaths) could be used?
Maybe Resolved Fatality Rate? That reflects a denominator using resolved cases — they either died or recovered.
With CFR, TIME is the factor that makes it a smaller percentage, the time between infection and resolution. CFR would equal RFR only after the disease has run its course and all cases are resolved — they died or survived.
My 2 cents.
