Syphilis is referred to as a sexually transmitted disease, which is primarily caused due to bacteria and infects the genital area, mouth, lips and even anus of both males and females. It is usually occurred as a result of sexual contact with someone already infected with the disease. At the time of pregnancy, it may even pass from mother to baby. An early stage of the disease can be characterized by a single, tiny painless sore. At times, it may also cause swelling in adjacent lymph nodes. If left untreated, it can lead to a non-itchy skin rash, particularly on your hands and feet. Syphilis can be easily cured through antibiotics at its early stage though! With right use of latex condoms, it can be reduced largely but not eliminate completely the risk of spreading or catching syphilis.
