    About prevalence and incidence statistics:

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