Healthy Populations Exam 3 Practice

Morbidity is about illness in a population and the burden that disease creates. It’s often described by how often new cases occur (incidence) or how many people are living with a disease at a given time (prevalence). Describing morbidity as the incidence of a disease captures the idea that morbidity reflects the occurrence of illness contributing to the overall disease burden. The death rate is about mortality, not morbidity. The number of cases at a single point in time describes point prevalence, which is a measure of morbidity but not the full concept on its own. The total population at risk is the denominator used to calculate rates, not a direct description of disease burden. Keep in mind that morbidity isn’t limited to notifiable diseases; it covers illness from any disease in the population.
