Prevalence and Incidence of Chancroid


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

Incidence (annual) of Chancroid: 143 annual cases notified in USA 1999 (MMWR 1999); rare in the USA but with occasional outbreaks.
Incidence Rate: approx 1 in 1,902,100 or 0.00% or 143 people in USA [about data]
