Congenital Cytomegalovirus Overview
Congenital cytomegalovirus (cCMV) is a common infection that occurs during pregnancy. Cytomegalovirus (CMV) is a virus that belongs to the same family as other common viruses like the chicken pox virus. When children or adults catch CMV it is generally harmless and causes no symptoms. Young children are a common source of CMV and may spread it to their parents.
However, if a pregnant woman catches CMV and the growing fetus becomes infected, this can lead to later symptoms after birth. This is known as congenital CMV. Most babies born with cCMV do not develop symptoms, however some are born with symptoms at birth or develop them later in life.
