Syphilis is a sexually transmitted infection that is transmitted from person to person by direct contact with a syphilitic sore, known as a chancre. Chancres can occur on or around the external genitals, in the vagina, around the anus, or in the rectum, or in or around the mouth. Syphilis can occur during vaginal, anal, or oral sex, and during childbirth.
Symptoms appear between 10 – 90 days. Syphilis follows a progression of (3) stages that can last for weeks, months, or even years.
