Cytomegalovirus infection and pregnancy

Some simple tips for your baby

What is cytomegalovirus (CMV)?​​​​​​​

Cytomegalovirus is a virus from the herpes family of viruses. It is transmitted through bodily fluids, particularly saliva, tears and urine. Usually, this infection is contracted in childhood. Children under the age of three, especially those in collective childcare facilities, are frequently exposed. As a result, 50 to 90% of adults are immune.
This infection can have foetal consequences if contracted during pregnancy. 

Am I at risk?

All pregnant women are potentially at risk, regardless of whether they have CMV antibodies in their blood.

What are the risks to my foetus?​​​​​​​

Transmission of cytomegalovirus from the mother to the foetus has, in most cases, no impact on the foetus. On rare occasions, it can result in neurosensory problems of varying severity (for example, deafness). The severity of the problems will also depend on the gestational age when the virus is contracted.

How can I avoid getting infected with CMV during my pregnancy?

Young children represent the main source of the virus. Taking preventative measures among pregnant women and their partners who have contact with young children is an effective way of reducing the risk of maternal infection during pregnancy, especially up to 16 weeks of gestation. 

It is recommended that all pregnant women and their partners take the following steps, particularly during the first trimester: 
• Avoid coming into contact with the bodily fluids of young children that could be infected (tears, saliva, urine, nasal mucus). 
• Wash your hands regularly with soap and water, and particularly after changing a nappy or blowing a child's nose.  
• Don't share cutlery or cups with children, don't use their toiletry items and avoid kissing children on the mouth.

Have a discussion with your health professional (doctor, obstetrician, midwife, etc.).
