Prevalence and Incidence of Impotence


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