Prevalence and Incidence of Temporal arteritis

Prevalance of Temporal arteritis:

200 per 100,000 people over 50. ... see also overview of Temporal arteritis.

Prevalance Rate:

approx 1 in 500 or 0.20% or 544,000 people in USA [Source statistic for calcuation: "200 per 100,000 people over 50." -- see also general information about data sources]

Temporal arteritis: Rare Disease

Temporal arteritis is listed as a "rare disease" by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH). This means that Temporal arteritis, or a subtype of Temporal arteritis, 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 Temporal arteritis as a "rare disease". More information about Temporal arteritis is available from Orphanet

Prevalance of Temporal arteritis:

An estimated 200 per 100,000 people over the age of 50 develop giant cell arteritis. (Source: excerpt from Questions and Answers About Polymyalgia Rheumatica and Giant Cell Arteritis: NIAMS)

About prevalence and incidence statistics:

The term 'prevalence' of Temporal arteritis usually refers to the estimated population of people who are managing Temporal arteritis at any given time. The term 'incidence' of Temporal arteritis refers to the annual diagnosis rate, or the number of new cases of Temporal arteritis 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. For more information see about prevalence and incidence statistics.
