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

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