About prevalence and incidence statistics:
The term 'prevalence' of Inflammatory bowel disease usually refers to the estimated population
of people who are managing Inflammatory bowel disease at any given time.
The term 'incidence' of Inflammatory bowel disease refers to the annual diagnosis rate,
or the number of new cases of Inflammatory bowel disease 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.
