The medical term 'incidence' of Digestive Diseases usually refers
to the annual diagnosis rate of new cases of Digestive Diseases.
Prevalence is a different medical disease measure that refers
to the estimated population
of people who are managing Digestive Diseases at any given time (e.g. prevalence includes people who have had
a medical condition for a long time).
For more information on prevalence and incidence statistics, see about prevalence and incidence statistics.
