About prevalence and incidence statistics:

The term 'prevalence' of Polymyalgia rheumatica usually refers to the estimated population of people who are managing Polymyalgia rheumatica at any given time. The term 'incidence' of Polymyalgia rheumatica refers to the annual diagnosis rate, or the number of new cases of Polymyalgia rheumatica 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.
