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 and urine. Usually, this infection is contracted in childhood. As a result, 50-90% of adults are immune. More rarely, this infection can occur 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 (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. If you are a pregnant woman in contact with young children, taking preventative measures is an effective way of reducing the risk of maternal infection during pregnancy. 

It is recommended that all pregnant women and their partners take the following steps, especially 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, and particularly after changing a nappy or blowing a child's nose. 
• Don't share cutlery 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.).
