The word 'prevalence' of Digestive Diseases usually means the estimated population
of people who are managing Digestive Diseases at any given time (i.e. people with Digestive Diseases).
The term 'incidence' of Digestive Diseases means the annual diagnosis rate,
or the number of new cases of Digestive Diseases diagnosed each year (i.e. getting Digestive Diseases).
Hence, these two statistics types can differ:
a short disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
For more information see about prevalence and incidence statistics.
