Syphilis

Syphilis is a sexually transmitted infection caused by Treponema pallidum. It is transmitted through vaginal, anal or oral sex and can also be transmitted from infected mother to infant during pregnancy or birth. Early symptoms can include genital sores, rash and headache. Untreated, syphilis can eventually affect the brain and nervous system. Prenatal testing and condom use can reduce risk of spread.
