Syphilis is caused by a bacterium. It is uncommon. There were 250 cases diagnosed in Indiana in 2005. Upon initial infection syphilis causes a painless ulcer. Women may not notice this ulcer depending upon where it occurs. Men usually will see it on their penis. Syphilis can be cured with penicillin. If it is not treated, it can cause serious problems including infection of the brain and spinal cord with resulting paralysis and confusion.  You can be tested for syphilis in the Health Center and Women's Center.

You can find more information about syphilis on the CDC website.
