Syphilis is a sexually transmitted disease (STD) caused by an infection with bacteria known as Treponema pallidum. Like other STDs, syphilis can be spread by any type of sexual contact. Syphilis can also be spread from an infected mother to the fetus during pregnancy or to the baby at the time of birth.
Syphilis has been described for centuries. Today, about 55,000 people in the U.S. get new syphilis infections each year. It can cause long-term damage to different organs if not properly treated.
