Autoimmune Hepatitis: Rare Disease
Autoimmune Hepatitis is listed as a "rare disease" by the Office of
Rare Diseases (ORD) of the National Institutes of Health
(NIH). This means that Autoimmune Hepatitis, or a subtype of Autoimmune Hepatitis,
affects less than 200,000 people in the US population.
About prevalence and incidence statistics:
The term 'prevalence' of Autoimmune Hepatitis usually refers to the estimated population
of people who are managing Autoimmune Hepatitis at any given time.
The term 'incidence' of Autoimmune Hepatitis refers to the annual diagnosis rate,
or the number of new cases of Autoimmune Hepatitis 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.
