Syphilis is an infection that spreads from person to person through sexual contact. In nonpregnant persons, syphilis can cause penile or vaginal discharge; skin sores or rashes; fever; and, if untreated, nervous system problems. In pregnant women, untreated syphilis can lead to serious problems in babies, including stillbirth or death soon after birth, bone deformities, and nervous system problems. Fortunately, syphilis is treatable with antibiotics. Doctors can screen patients for syphilis with a blood test and follow-up tests to confirm infection if the first test shows possible infection. Screening means testing people who do not have symptoms. In 2004, the USPSTF recommended that all pregnant women have screening tests for syphilis at their first prenatal health care visit.
