的確是兩個概念。 CNN說的就是fatality rate, 而且它的計算是對的

Case fatality rate is calculated by dividing the number of deaths from a specified disease over a defined period of time by the number of individuals diagnosed with the disease during that time

 

mortality rate is calculated by dividing the number of deaths by the population at risk during a certain time frame.
