About statistics:

This page presents a variety of statistics about Spinal Muscular Atrophy. The term 'prevalence' of Spinal Muscular Atrophy usually refers to the estimated population of people who are managing Spinal Muscular Atrophy at any given time. The term 'incidence' of Spinal Muscular Atrophy refers to the annual diagnosis rate, or the number of new cases of Spinal Muscular Atrophy 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.
