CDC – Syphilis
Syphilis is an infection caused by the bacteria Treponema pallidum. Many people do not have symptoms when they have an infection with syphilis, but some people do have painless sores, rash, fever, swollen lymph nodes, sore throat, patchy hair loss, joint pain, and fatigue. If left untreated, syphilis can lead to serious complications including organ damage. The syphilis bacteria can be passed from a mother to her unborn baby during pregnancy or childbirth and can have serious impact on the baby. Syphilis testing is done with a blood draw. Syphilis is treatable but repeatable.
