In medicine and epidemiology, the term morbidity can refer to

• the state of being diseased (from Latin morbidus: sick, unhealthy),
• the degree or severity of a disease,
• the prevalence of a disease: the total number of cases in a particular population at a particular point in time,
• the incidence of a disease: the number of new cases in a particular population during a particular time interval.

Accordingly, the term morbidity rate can refer either to the incidence rate or to the prevalence rate of a disease. Compare with mortality rate, the number of people dying from a particular disease during a given time interval, divided by the total number of people in the population. Morbidity is often what is measured by ICU scoring systems.
