About prevalence and incidence statistics:
The term 'prevalence' of Digestive Diseases usually refers to the estimated population
of people who are managing Digestive Diseases at any given time.
The term 'incidence' of Digestive Diseases refers to the annual diagnosis rate,
or the number of new cases of Digestive Diseases diagnosed each year.
Hence, these two statistics types can differ:
a short-lived 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.
