Spina bifida: Rare Disease

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

Ophanet, who are a consortium of European partners, currently defines a condition rare when if affects 1 person per 2,000. They list Spina bifida as a "rare disease". More information about Spina bifida is available from Orphanet

    About prevalence and incidence statistics:

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