Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum. It’s primarily spread through sexual contact and usually starts off as a painless sore on your genitals, rectum or mouth [1].

Syphilis symptoms


Syphilis commonly occurs in stages and the symptoms are dependent on the stage. Although the indicators aren’t always obvious, some of the most common for each stage include [2]:


Primary syphilis


  • Painless and small sore at the site of infection

Secondary syphilis


  • Skin rash
  • Swollen lymph nodes
  • Fever

Latent syphilis


If you aren’t treated for syphilis, the infection moves from the secondary stage to the latent stage where there are no noticeable signs or symptoms.

Tertiary stage


According to Mayo Clinic, about 15-30% of people with syphilis who don’t receive treatment will develop complications referred to as tertiary, or late, syphilis [3].

These complications can include:

  • Damage to the brain nerves, eyes, heart, blood vessels, liver, bones and joints

What does syphilis look like?


One of the first indicators of syphilis is a small chancre, commonly referred to as a sore. This sore usually occurs around the genitals, rectum or mouth and appears firm, round and painless.
