Syphilis is infection with the bacteria Treponema pallidum.

Symptoms

The symptoms of syphilis depend on the stage of the disease. Many people do not have symptoms.

In general, painless sores and swollen lymph nodes are possible symptoms of primary syphilis. Those with secondary syphilis may also have fever, fatigue, rash, aches and pains, and loss of appetite, among other symptoms. Tertiary syphilis causes heart, brain, and nervous system problems.

For more information, see the article on the specific stage of syphilis.
