Prevalence and Incidence of Ocular Herpes

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