Prevalence and Incidence of Acatalasemia
Acatalasemia: Rare Disease
Acatalasemia is listed as a "rare disease" by the Office of
Rare Diseases (ORD) of the National Institutes of Health
(NIH). This means that Acatalasemia, or a subtype of Acatalasemia,
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 Acatalasemia as a "rare disease".
More information about Acatalasemia is available from Orphanet
About prevalence and incidence statistics:
The term 'prevalence' of Acatalasemia usually refers to the estimated population
of people who are managing Acatalasemia at any given time.
The term 'incidence' of Acatalasemia refers to the annual diagnosis rate,
or the number of new cases of Acatalasemia 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.
