What is syphilis?

Syphilis is a sexually transmitted infection. It’s a bacterial infection that spreads by having unprotected sex or through using unclean needles or an unscreened blood transfusion. Syphilis is diagnosed with a blood test.

The infection starts as a painless sore on the genitals, rectum or mouth. It can then develop into a rash or more serious symptoms. Syphilis is treated with antibiotics, and it’s important to get treated as soon as possible. You will also need to tell your past sexual partners so they can be treated.
