Syphilis is a sexually transmitted disease (STD) that can cause long-term complications if not treated properly. Symptoms of syphilis in adults include a painless sore that goes away without treatment, followed by a non-itchy rash. If left untreated, syphilis can lead to bodily harm, including neurological and cardiovascular complications. Syphilis also increases the risk of HIV infection and, for women, can cause problems during pregnancy and for the newborn.
