title: Maternal, fetal and neonatal diagnosis of congenital human cytomegalovirus infection.
abstract: BACKGROUND
  The socio-economic burden associated with congenital human cytomegalovirus (HCMV) infection is well recognized. Nevertheless, women are neither informed nor tested for HCMV antibody, and in the absence of screening, HCMV infections proceed mostly undiagnosed during pregnancy.
  
  
  METHODS
  Knowledge has accumulated concerning both the natural history of HCMV infection and the availability of diagnostic tests.
  
  
  RESULTS
  Different assays for the diagnosis in the mother, fetus and newborn are well established. In addition, positive and negative predictive values of different assays for prenatal diagnosis have improved over time.
  
  
  CONCLUSIONS
  Without an HCMV vaccine, diagnosis of primary infection in the mother and of congenital infection in the fetus/newborn are key factors for management of congenital HCMV infection.
