Epidemiology- What is Incidence and Prevalence in Epidemiology? Incidence Vs Prevalence

Epidemiology- What is Incidence and Prevalence in Epidemiology? Incidence Vs Prevalence. Incidence and prevalence both are measures of morbidity. Measures of morbidity frequency characterize the number of persons in a population who become ill (incidence) or are ill at a given time (prevalence). Incidence refers to the occurrence of new cases of disease or injury in a population over a specified period of time. Although some epidemiologists use incidence to mean the number of new cases in a community, others use incidence to mean the number of new cases per unit of the population. Two types of incidence are commonly used — incidence proportion and incidence rate. Prevalence, sometimes referred to as prevalence rate, is the proportion of persons in a population who have a particular disease or attribute at a specified point in time or over a specified period of time. Prevalence differs from incidence in that prevalence includes all new and preexisting cases in the population at the specified time, whereas incidence is limited to new cases only. Point prevalence refers to the prevalence measured at a particular point in time. It is the proportion of persons with a particular disease or attribute on a particular date. Period prevalence refers to prevalence measured over an interval of time. It is the proportion of persons with a particular disease or attributes at any time during the interval.
