About prevalence and incidence statistics:
The term 'prevalence' of Irritable bowel syndrome usually refers to the estimated population
of people who are managing Irritable bowel syndrome at any given time.
The term 'incidence' of Irritable bowel syndrome refers to the annual diagnosis rate,
or the number of new cases of Irritable bowel syndrome 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.
For more information see about prevalence and incidence statistics.
