Syphilis is a serious, systemic STD caused by the Treponema palladium bacteria. Syphilis infection is divided into several stages: primary, secondary, early latent (EL), late latent, and congenital. Each stage of syphilis requires different treatment. For more information on syphilis diagnosis and treatment, please call PDPH at (215) 685-6737.
