If a CMV negative woman becomes infected during pregnancy, the fetus could become infected, too. This is known as a congenital infection and occurs in about one-third of cases.
Twenty percent of babies born with a CMV infection develop complications in their first few years of life. This may include:
- Low birth weight
- Deafness
- Blindness
- Intellectual disability
- Small head
- Seizures
- Jaundice
- Brittle teeth
- Liver or spleen damage
No baby develops all symptoms listed above, with the majority showing no symptoms at all.
