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

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