    About prevalence and incidence statistics:

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