Epidemiology

  • Risk of transmission to fetus
    • Primary infection: 30% risk of congenital CMV; higher risk later in pregnancy, but worse outcomes earlier
    • Non-primary
      • Reinfection: 5% risk
      • Reactivation: 1% risk

Clinical Presentation

Diagnosis

  • In mom, IgM antibodies
  • In baby, urine PCR within 2 weeks of birth

Management

  • Treatment is indicated for symptomatic babies
    • Brain
    • Hearing
    • Eye
  • IV ganciclovir or PO valganciclovir, for 6 months
  • Monitor CBC while on therapy
