Syphilis symptoms and signs are related to the stage of the infection. The first stage involves the appearance of a painless sore on the genitals, rectum, or mouth. After the sore heals, the second stage will usually manifest with a rash. Finally, after a long period with no  symptoms, the third stage can suddenly develop, causing extensive damage to the brain, nerves, eyes, or heart.

Because the syphilis symptoms are often non-specific (or mimic other conditions like psoriasis, hemorrhoids, and canker sores), infections are sometimes untreated. It is for this reason that we refer syphilis as the “great imitator.”

What this infection looks and feels like changes as it evolves, and can vary between the different types.

Primary Syphilis

Primary syphilis will typically start with the appearance of a chancre anywhere from three to 90 days after the initial exposure (average 21 days). The sore will develop at the point of contact, most commonly on the cervix, vagina, penis, anus, rectum, or mouth.

There may be one or more lesions ranging in size from an eighth of an inch to an inch or more. Because the sores are painless, they can be easily missed if internalized. Swollen lymph glands can also occur, usually near the site of the infection.

Without treatment, a chancre will heal in anywhere from three to six weeks.

Secondary Syphilis

If left untreated, a primary infection will progress to secondary syphilis. Symptoms typically appear within four to 10 weeks of the appearance of a chancre. During this stage, a person may feel sick and experience fever, sore throat, fatigue, weight loss, and headache. A generalized swelling of the lymph nodes (generalized lymphadenopathy) is also common.

One of the more characteristic symptoms of secondary syphilis is a widespread, non-itchy rash on the trunk, limbs, and (most tellingly) the palms and soles of the feet. With that being said, the appearance of the rash can vary dramatically.

Secondary syphilis can also manifest in rare, unusual, and varied ways affecting the liver, kidneys, bones, and central nervous system—why it’s often referred to as “the great imitator” or “the great masquerader.”

The symptoms of secondary syphilis will typically resolve without treatment within three to six weeks.

Latent Syphilis

Latent syphilis is the third stage of infection marked by the relative absence of the symptoms but positive blood tests. It is further divided into two stages:

  • Early latent syphilis is the period of less than a year from the last blood test. Secondary symptoms can sometimes relapse during the early latent phase.
  • Late latent syphilis is the period greater than a year from the last blood test. It can last for years and even decades with no signs of disease.

While the infection can be passed during the early latent stage, it is less likely to do so during the later stages of latency.

The duration of latency is highly variable, and scientists are not exactly sure why. One of the factors known to accelerate progression is HIV co-infection. On the one hand, an open chancre sore provides HIV an easy route into the body. On the other, having HIV and syphilis together increases the risk of late-stage complications even during the early stages of infection.

Tertiary Syphilis

Tertiary syphilis is the most serious stage of infection and we characterize them by three major complications:

  • Gummatous syphilis causes the formation of soft, tumor-like lesions called gummas. These non-cancerous lesions can cause large ulcerative sores on the skin and mouth, and erode tissues of heart, liver, muscles, bones, and other vital organs. The symptoms can develop as early as a year following exposure or as many as 50 years later.
  • Cardiovascular syphilis can cause severe inflammation of the aorta and the development of an aortic aneurysm (the swelling and weakening of the aortic wall). The symptoms of cardiovascular syphilis commonly appear 10 to 30 years after primary infection.
  • Neurosyphilis affects the central nervous system and usually develops within four to 25 years of an infection. While some people will remain symptom-free, others may experience severe neurological syphilis symptoms including meningitis (inflammation of the membrane surrounding the brain and spinal cord) or tabes dorsalis (a condition characterized by nerve pain, loss of motor skills, visual impairment, deafness, and incontinence). Seizures, personality changes, hallucinations, dementia, schizophrenia, and stroke can also occur.

Syphilis is not contagious during the tertiary stage.

Complications in Newborns

Congenital syphilis is a serious condition in which a pregnant mother with this infection passes T. pallidum to her developing baby.

Untreated syphilis during pregnancy can sometimes lead to miscarriage or stillbirth. Of the babies born with syphilis, as many as two-thirds will have no symptoms during the first couple of years of life. If left untreated, the symptoms may include:

  • Liver and spleen enlargement
  • Petechia (purplish skin spots caused by ruptured capillaries)
  • Profuse nasal drip (known as syphilitic “snuffles”) with highly infectious mucus discharge
  • Neurosyphilis
  • Lung inflammation
  • Jaundice (yellowing of the skin and eyes)
  • Seizures

By age 2, the child may have characteristic facial or physical deformities and significant sensory impairment, including:

  • Blunted upper front teeth (known as Hutchinson’ teeth)
  • A collapse of the bony part of the nose (saddle nose)
  • A protruding jawbone and foreshortened upper jaw
  • A protruding frontal bone of the skull (frontal bossing)
  • Swollen knees
  • Bowing of the shin bones (saber shins)
  • Inflammation and scarring of the cornea (interstitial keratitis)
  • Glaucoma
  • Deafness
  • Developmental delays

Related death in these children is most often caused by a lung hemorrhage.

It can be treated successfully in the early stages.

When is it safe to have sex?

You must avoid sexual contact until:

  • all treatment is complete
  • a blood test confirms that the disease is gone

It may take several months to see blood tests go down to an appropriate level. This would provide confirmation of adequate treatment.


Preventive measures to decrease the risk, include:

  • abstaining from sex
  • long-term mutual monogamy with an uninfected partner
  • condom use, although these protect only against genital sores and not those on the body.
  • use of a dental dam, or plastic square, during oral sex.
  • not sharing sex toys
  • avoiding alcohol and drugs that could potentially lead to unsafe sexual practices

Having it once does not mean a person is protected from it.
