here’s what you need to know about what syphilis looks like and how you can protect yourself.
signs and symptoms
a syphilis infection usually starts with painless sores on the mouth, genitals or rectum,
according to the mayo clinic. that’s often followed by a rash that begins on the stomach, chest or back and spreads across the entire body. there may be more sores at this point, often in the mouth or the genitals. muscles aches, fever, and swollen lymph nodes sometimes occur in this stage.
these first two stages are when it’s most infectious — but they’re also when it’s most easily confused with other illnesses.
these symptoms might go away, but that doesn’t mean the syphilis is gone — in fact, it could mean it’s gone into the hidden or latent stage, which can last for years before, in some cases, developing to tertiary syphilis. it can also affect the eyes (called ocular syphilis) or the brain and nervous system (neurosyphilis).
you should get tested or see a doctor if you experience unusual rashes, discharge or sores — especially if they’re in the groin.
causes and risk factors
having sex without using a condom or dental dam is one of the biggest risk factors for syphilis. making sure to use protection is the easiest and most effective way for sexually-active people to protect themselves from stis.
