You are conducting a study on a new type of infectious disease and find that the case fatality rate is high. It means that:
Case fatality rate = Total number of deaths due to a paicular disease/Total number of cases of the same disease It is a measure of the killing power of a disease and is closely related to the virulence. Ref: Park, Edition 21, Page - 54.
The disease is highly infective
The disease has a sho incubation period
The disease is caused by a virulent organism
All the above
