This page presents a variety of statistics about Lyme disease. The term 'prevalence' of Lyme disease usually refers to the estimated population of people who are managing Lyme disease at any given time. The term 'incidence' of Lyme disease refers to the annual diagnosis rate, or the number of new cases of Lyme disease 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.
