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

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