Syphilis can cause varied symptoms and the progression of the illness can vary widely. It is therefore often overlooked or mistaken for a different illness.
Initially, a small ulcer often develops at the site where the pathogen entered the body, for example on the penis, in the vagina, in the anal area or in the mouth. There may also be swelling of the lymph nodes. These symptoms usually go away of their own accord.
After around two to three months, symptoms such as fever, headache and joint pain may appear. Skin rashes and a coating on the tongue are also common. These signs of illness also subside on their own. After that, there are usually no more signs of syphilis.
If, however, years later, it progresses to a third phase of illness (tertiary syphilis), ulcers appear all over the body. The organs and the nervous system may be damaged - possibly leading to deafness, blindness and psychiatric problems. Today, however, thanks to effective treatment options, it rarely reaches this stage.
