Syphilis

Syphilis is a sexually transmitted infection (STI) caused by bacteria.

Primary stage

• A painless sore may appear at the site of entry (mouth, genitals, anus) 10 to 90 days after exposure.
• This sore heals without treatment in a few weeks, but the syphilis germ remains in the body.

Secondary stage

• You may have flu-like symptoms 4 to 10 weeks after the primary stage.
• A rash may appear on the palms of the hands, the soles of the feet, or elsewhere.
• The rash disappears without treatment, but the syphilis germ remains in the body.
• You are highly contagious during this phase.

Latent stage

• You may not show any symptoms during this phase.

Tertiary stage

• Without treatment, syphilis can cause paralysis, loss of vision, heart and nerve problems, or death 10 to 30 years later.

Syphilis can be transmitted through sexual contact (oral, vaginal, or anal). Pregnant women who are infected can transmit syphilis to their fetus, likely causing serious harm that may lead to the death of the fetus.

Testing can involve a simple blood test or a swabbing of the sore. Other tests depend on the stage and symptoms.
