Living with Congenital Epstein-Barr virus infection

A rare infection a baby can have from birth that causes no symptoms in most infants but, rarely, causes multiple differences.

Understanding Congenital Epstein-Barr virus infection

Congenital Epstein-Barr virus infection is a rare infection present at birth that causes no signs in most infants.

Rarely, after birth, babies have several birth differences such as a small jaw, undescended testes and cataracts. They may also have slow growth, low muscle tone, an enlarged liver and spleen, small red spots on the skin and bruises, and changes in long bones. Low birth weight may also be reported. It is seen in newborns and infants.

Signs & symptoms

Most infants have no symptoms. GARD's summary lists these rare features:

  • Small jaw (micrognathia)
  • Undescended testes
  • Cataracts
  • Low muscle tone (hypotonia)
  • Enlarged liver and spleen
  • Small red spots and bruises

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