Prevalence and Incidence of Mycosis fungoides
Mycosis fungoides: Rare Disease
Mycosis fungoides is listed as a "rare disease" by the Office of
Rare Diseases (ORD) of the National Institutes of Health
(NIH). This means that Mycosis fungoides, or a subtype of Mycosis fungoides,
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 Mycosis fungoides as a "rare disease".
More information about Mycosis fungoides is available from Orphanet
About prevalence and incidence statistics:
The term 'prevalence' of Mycosis fungoides usually refers to the estimated population
of people who are managing Mycosis fungoides at any given time.
The term 'incidence' of Mycosis fungoides refers to the annual diagnosis rate,
or the number of new cases of Mycosis fungoides 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.
