Canavan disease: Rare Disease

Canavan disease is listed as a "rare disease" by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH). This means that Canavan disease, or a subtype of Canavan disease, affects less than 200,000 people in the US population.

About prevalence and incidence statistics:

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