Primary biliary cirrhosis: Rare Disease
Primary biliary cirrhosis is listed as a "rare disease" by the Office of
Rare Diseases (ORD) of the National Institutes of Health
(NIH). This means that Primary biliary cirrhosis, or a subtype of Primary biliary cirrhosis,
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 Primary biliary cirrhosis as a "rare disease".

Cirrhosis and fibrosis:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
These clinical types of cirrhosis reflect its diverse etiology:
❑ Portal, nutritional, or alcoholic (Laennec’s) cirrhosis, the most common type, occurs in 30% to 50% of cirrhotic patients, up to 90% of whom have a history of alcoholism. Liver damage results from malnutrition, especially of dietary protein, and chronic alcohol ingestion. Fibrous tissue forms in portal areas and around central veins.
❑ Biliary cirrhosis (15% to 20% of patients) results from injury or prolonged obstruction.
❑ Postnecrotic (posthepatic) cirrhosis (10% to 30% of patients) stems from various types of hepatitis.
❑ Pigment cirrhosis (5% to 10% of patients) may result from disorders such as hemochromatosis.
❑ Cardiac cirrhosis (rare) refers to liver damage caused by right-sided heart failure.
❑ Idiopathic cirrhosis (about 10% of patients) has no known cause.
Noncirrhotic fibrosis may result from schistosomiasis or congenital hepatic fibrosis or may be idiopathic.

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