What are the symptoms of syphilis?

Syphilis is an infection that can stay in the body for years if not recognized and treated promptly. There are three stages of syphilis, and each stage has distinct symptoms.

Symptoms of primary syphilis

Primary syphilis is the first stage of syphilis. Symptoms include:

  • A painless lesion called a chancre develops any time from 10 days to three months after exposure.

  • The chancre generally appears on the genital area but can also form on the lips, tongue or rectum if these areas have been exposed to a syphilis chancre on another person during oral or anal sexual contact. A chancre in the vagina, mouth or rectum is generally not easily seen.

  • The chancre heals in one to five weeks.

Symptoms of secondary syphilis

If left untreated, primary syphilis progresses to a second stage called secondary syphilis. In this stage, the bacteria that cause syphilis spread throughout the body and cause additional symptoms. Symptoms begin to appear about six weeks after the chancre has resolved and include:

  • Fatigue

  • Fever

  • Flu-like symptoms

  • Headache

  • Patchy hair loss

  • Skin rashes and a rash around the rectum (these rashes do not itch, and exposure to these rashes can transmit syphilis to others)

  • Sore throat

  • Swollen glands

  • Weight loss

Symptoms of tertiary syphilis

The third and final stage of syphilis is called tertiary or late-stage syphilis, which develops from untreated secondary syphilis. When untreated secondary syphilis symptoms disappear, the infection still continues in the body.

Symptoms of tertiary syphilis may not appear for 10 to 20 years after initial infection with syphilis. During this time, syphilis can damage organs, such as the brain, heart, blood vessels, liver, bones, and nerves, leading to serious complications.

Symptoms of tertiary syphilis include:

  • Gradual loss of vision

  • Loss of muscle coordination

  • Numbness

  • Paralysis
