Cytomegalovirus (CMV) is a virus that causes infections that often pass unnoticed. 

A cytomegalovirus infection in pregnant women can cause damage to the fetus.

This is the most common congenital fetal infection in industrialized countries.

In early pregnancy the physician will perform a blood test to check whether or not you have already had the virus.

In non-immunized pregnant women, the risk of infection is increased by the fact of having a toddler, working at a daycare center or with the elderly and/or immunosuppressed.

Contamination occurs through contact with bodily secretions.


  • 10% of cases: flu-like illness;
  • 5% of cases: prolonged fever.

If you have a flu-like illness or fever, it is advisable to consult your physician. The diagnosis is based on the presence of antibodies in the blood of the mother.

To prevent the appearance of this virus, rigorous hand hygiene is necessary.
