Syphilis is a sexually transmitted disease (STD) that is found around the world. In the United States it is more widespread in parts of the south. What causes syphilis? Syphilis is caused by bacteria (Treponema pallidum) that enter through your skin, mouth, or anus.
Syphilis spreads from person to person via skin or mucous membrane contact with these sores. After the initial infection, the syphilis bacteria can lie dormant in your body for decades before becoming active again. Early syphilis can be cured, sometimes with a single injection of penicillin. Without treatment, syphilis can severely damage your heart, brain or other organs, and can be life-threatening, or be passed from mother to an unborn child.
