What is cytomegalovirus infection?
Cytomegalovirus (CMV) is a virus from the herpes virus family. Is the more common congenital infection, affects 3-4 / 1,000 live births. In Europe, 50% of women are susceptible to the disease during pregnancy. About 1% of susceptible women will develop the infection during pregnancy and, in half of the cases, the newborn will become infected.
Infection can occur in any time of pregnancy or during the neonatal period (by intimate contact with people who are infected, by breastfeeding if the mother has the disease, or by blood transfusion contaminated by CMV).
Cytomegalovirus infection symptoms
It is a mild infection or without symptoms (the mother does not realize that she is suffering from it because she does not feel sick). The 90% of fetuses who become infected suffer no repercussions at birth and its development is normal. However, 5% of affected babies can develop deafness over time.
5% have symptoms of infection at birth:
- Cerebral palsy
- Microcephaly (abnormally small head)
- Deafness
- Seizures
- Learning difficulties
- Lung involvement (pneumonitis)
- Jaundice
- Anemia and decreased platelets
- Ocular involvement
- Spleen and liver enlargement
- Death
Treatment and prevention
Currently there is no no effective treatment for infection congenital or neonatal due to cytomegalovirus. Cytomegalovirus screening tests in pregnant women are not routinely performed during pregnancy; this is so because the overall risk of serious disease to the fetus is very low. Nurseries and hospitals are the places where cytomegalovirus infection is most common. Good hand washing is recommended to avoid contagion.
