The number of the existing cases of disease or injury in a defined population at a given point in time. NOTE: The relation between incidence and prevalence varies among diseases. There may be low incidence and a high prevalence - as for diabetes - or a high incidence and a low prevalence - as for the common cold. [After Basic Epidemiology, R. Bonita and others, WHO 2006; After Principles of Epidemiology in Public Health Practice, Third Edition. An Introduction to Applied Epidemiology and Biostatistics, Lesson 3: Measures of Risk, CDC 2012] Compare to incidence. See also morbidity rate, morbidity, mortality, incidence rate.
