Infection from the spirochete Treponema pallidum causes syphilis. Transmission occurs primarily through sexual contact during the primary, secondary, and early latent stages of infection. Prenatal transmission from an infected mother to her fetus is also possible. (See Prenatal syphilis.)
Incidence is highest in people ages 20 to 29.

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