What is incidence rate in epidemiology?
Put simply, the incidence rate is the number of new cases within a time period (the numerator) as a proportion of the number of people at risk for the disease (the denominator). This measure is commonly used in epidemiology as a way to denote the occurrence of disease, illness, or accident.
How is incidence expressed?
It is calculated dividing the number of new cases during a given period by the number of subjects at risk in the population initially at risk at the beginning of the study. Where the period of time considered is an entire lifetime, the incidence proportion is called lifetime risk.
