Syphilis is a sexually transmitted disease (STD). If left untreated, syphilis can cause brain, nerve, tissue damage, and death. Fortunately, syphilis can be treated with antibiotics.
Syphilis is caused by a specific bacteria. It is passed through direct contact with a syphilis lesion, which may happen through:
- Vaginal, anal, or oral sexual contact with an infected person
- A pregnant woman who passes the infection to her unborn baby (called congenital syphilis)
