Prevalence and Incidence of Ciguatera poisoning
Ciguatera poisoning: Rare Disease
Ciguatera poisoning is listed as a "rare disease" by the Office of
Rare Diseases (ORD) of the National Institutes of Health
(NIH). This means that Ciguatera poisoning, or a subtype of Ciguatera poisoning,
affects less than 200,000 people in the US population.
Prevalance of Ciguatera poisoning:
The relative frequency of ciguatera fish poisoning in the United States is not known. The disease has only recently become known to the general medical community, and there is a concern that incidence is largely under-reported because of the generally non-fatal nature and short duration of the disease.

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