Syphilis is a common sexually transmitted infection that can cause serious illness. Having an active syphilis infection increases the risk you will get HIV or give HIV to someone else. HIV is incurable and can be fatal. If you are a pregnant woman, syphilis increases the risk that the pregnancy will end in miscarriage, death of the baby at birth or in infancy, or permanent disabilities for your baby. Fortunately, syphilis can be diagnosed with a blood test and cured with antibiotics. http://archive.org/details/DoIHaveSyphilisSignsAndSymptomsOfSyphilis.
