About statistics:

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