How is syphilis spread?
Syphilis can be spread during vaginal, anal, or oral sex through contact with an open sore or contact with a skin rash. The bacteria can enter the body through the penis, anus, vagina, mouth, or through broken skin. An infected pregnant woman can also pass the disease to her unborn child. Syphilis is not spread by contact with toilet seats, doorknobs, swimming pools, hot tubs, bathtubs, shared clothing, or eating utensils.
