Prevalence and Incidence of Ankle sprain

About prevalence and incidence statistics: The term 'prevalence' of Ankle sprain usually refers to the estimated population of people who are managing Ankle sprain at any given time. The term 'incidence' of Ankle sprain refers to the annual diagnosis rate, or the number of new cases of Ankle sprain 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. For more information see about prevalence and incidence statistics.
