About prevalence and incidence statistics:

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