How is severity different from incidence and prevalence?
Severity differs from incidence and prevalence in that it describes the impact or seriousness of the disease rather than the number of cases. Incidence refers to the number of new cases of a disease in a population over a specific time period, while prevalence is the total number of cases, both new and existing, in a population at a given time. Severity provides context to these measures by illustrating the potential consequences of the disease.
