It would seem in a emerging epidemic, where the time to resolve a disease is long, an evaluation might be used such as:
(predictive mortality rate) = (deaths) / (deaths + resolved)
Is this a standard metric? And if so what is it called?
It would seem that this kind of metric would be a predictor as to the ultimate mortality rate, unadjusted for treatment advances. The intent is to describe the demonstrated mortality of those who have acquired the disease, without influencing of the number of people who have acquired the disease. This would be helpful where R0 is large and/or Specific Interval is small. However I cannot find references to a metric similar to this. Pointers appreciated.
