Congenital Syphilis

Topic Overview

Congenital syphilis occurs when a mother'ssyphilisgoes untreated during pregnancy and is passed to the baby through theplacenta. A baby can also become infected with syphilis during labor or delivery.

The risk of infecting the baby is greatest when the mother is in the early stages of syphilis. But infection is possible any time during pregnancy.

It is very important that a pregnant woman have a blood test to detect syphilis. The baby's risk of getting syphilis is significantly reduced if the mother receives treatment during pregnancy. If the mother is treated before the 16th week of her pregnancy, the baby will usually not become infected.

If an infected mother does not receive treatment, the mother may miscarry, or the baby may be born dead, die shortly after birth, be born early, or be infected with syphilis.

Complications that can occur in a baby whose infected mother was not treated include:

  • A flat bridge of the nose (saddle nose).
  • Permanent incisor teeth that are peg-shaped, widely spaced, and notched at the end with a crescent-shaped deformity in the center (notched teeth or Hutchinson's teeth).
  • Inflammation of the cornea, which may cause blindness (interstitial keratitis).
  • A progressive, disabling, and life-threatening complication involving the brain (neurosyphilis).
  • Deafness.
  • Bone deformities.

Antibioticscan prevent progression of the disease in an infected baby. But problems that have already developed may not be reversible.

If the baby lives past the first 6 to 12 months and is not treated, the disease can progress to a latent stage in which no symptoms are present but complications can appear over time.
