Living with Fetal cytomegalovirus syndrome

Health problems that can happen when a baby is infected with cytomegalovirus (CMV) before birth.

Understanding Fetal cytomegalovirus syndrome

Fetal cytomegalovirus syndrome, also called congenital cytomegalovirus, is a group of symptoms that may occur when a baby is infected with CMV before birth.

Most infected babies never develop symptoms. About 10% have health problems or disabilities such as lung, liver, or spleen problems at birth, hearing or vision loss, intellectual disability, seizures, small head size, or lack of coordination. It happens when a mother is infected during pregnancy and passes the virus to the baby through the placenta.

Signs & symptoms

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

  • Hearing loss
  • Eye inflammation (chorioretinitis)
  • Enlarged liver and spleen
  • Intellectual disability
  • Low platelets or anemia
  • Small head size

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

    Specialists who may be involved include brain and nervous system specialists and seizure and epilepsy specialists.

  3. Ask which tests can help

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

  4. Connect with expert centers

    Epilepsy Foundation may keep lists of experts for this condition.
