Prevalence and Incidence of Neurofibromatosis-2
Prevalance of Neurofibromatosis-2:
1 per 25,000 people suffer from neurofibromatosis type 2, Genetics Home Reference website ... see also overview of Neurofibromatosis-2.
approx 1 in 25,000 or 0.00% or 10,880 people in USA [Source statistic for calcuation: "1 per 25,000 people suffer from neurofibromatosis type 2, Genetics Home Reference website" -- see also general information about data sources]
Neurofibromatosis-2: Rare Disease
Neurofibromatosis-2 is listed as a "rare disease" by the Office of
Rare Diseases (ORD) of the National Institutes of Health
(NIH). This means that Neurofibromatosis-2, or a subtype of Neurofibromatosis-2,
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 Neurofibromatosis-2 as a "rare disease".

About prevalence and incidence statistics:
The term 'prevalence' of Neurofibromatosis-2 usually refers to the estimated population
of people who are managing Neurofibromatosis-2 at any given time.
The term 'incidence' of Neurofibromatosis-2 refers to the annual diagnosis rate,
or the number of new cases of Neurofibromatosis-2 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.
