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