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

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