Which term is used to describe the rate of illness and disease?

The term that accurately describes the rate of illness and disease is morbidity. Morbidity encompasses the prevalence and incidence of diseases within a population, offering insights into how many individuals are affected by specific health conditions. This statistic is crucial for understanding public health trends and planning healthcare services.

Mortality, on the other hand, refers specifically to the rate of death within a population, which is a different measure than morbidity. Infant mortality focuses exclusively on the death rates among infants, while life expectancy calculates the average number of years a person is expected to live based on demographic factors. Each of these terms provides valuable information about health and disease but addresses different aspects of health statistics.
