Cytomegalovirus (CMV)

Cytomegalovirus is a common virus that is usually harmless. But sometimes it causes problems in babies if you get it during pregnancy.

Symptoms of cytomegalovirus include a high temperature, muscle aches and tiredness. Some people do not get any symptoms.

Cytomegalovirus is passed on through body fluids, such as semen, saliva and blood. Pregnant women can pass it to their baby before or during birth.

Cytomegalovirus is usually harmless and does not need treatment. Antiviral medicine may be used to treat babies and people with a weak immune system.

If you're pregnant, things you can do to help avoid cytomegalovirus include washing your hands regularly and not sharing cutlery with young children.
