Syphillis

The symptoms of syphilis usually begin with a small sore on the penis or vagina. Up to six months after the initial symptoms occur, you may experience flu-like symptoms, such as aching and shivering.
Syphilis can be easily treated during the early stages using a course of antibiotics for two weeks. It can also be treated during later stages of infection but any damage to the heart or nervous system may be irreversible.
