About prevalence and incidence statistics:

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