Prevalence and Incidence of Whooping Cough


advertisement

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