Prevalence and Incidence of Trichinosis

Trichinosis: Rare Disease

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

Prevalance of Trichinosis:

Infection was once very common; however, infection is now relatively rare. From 1991-1996, an annual average of 38 cases per year were reported. (Source: excerpt from Trichinosis: DPD)

About prevalence and incidence statistics:

The term 'prevalence' of Trichinosis usually refers to the estimated population of people who are managing Trichinosis at any given time. The term 'incidence' of Trichinosis refers to the annual diagnosis rate, or the number of new cases of Trichinosis 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.
