Living with Congenital syphilis

An infection passed from a mother to her baby during pregnancy that can affect the skin, liver, bones, eyes, and hearing.

Understanding Congenital syphilis

Congenital syphilis is a rare condition caused by the syphilis bacterium (Treponema pallidum) passing from an infected mother to her baby.

Early signs in the first two years can include a rash, an enlarged liver and spleen, bone inflammation, a runny nose, and eye inflammation. Later signs can include Hutchinson's teeth, eye cornea inflammation, and hearing loss. Other signs can include a saddle-shaped nose, shin changes, and seizures. It can start during pregnancy or in newborns.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Rash that may peel
  • Enlarged liver and spleen
  • Low platelet count (thrombocytopenia)
  • Bone and bone-lining inflammation
  • Small red or purple skin spots
  • Fluid buildup before birth (hydrops fetalis)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
