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

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