About prevalence and incidence statistics:

The term 'prevalence' of Anorexia Nervosa usually refers to the estimated population of people who are managing Anorexia Nervosa at any given time. The term 'incidence' of Anorexia Nervosa refers to the annual diagnosis rate, or the number of new cases of Anorexia Nervosa 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.
