Congenital cytomegalovirus (cCMV) is cytomegalovirus (CMV) infection in a newborn baby.[1] Most have no symptoms.[1] Some affected babies are small.[1] Other signs and symptoms include a rash, jaundice, hepatomegaly, retinitis, and seizures.[1][2] It may lead to loss of hearing or vision, developmental disability, or a small head.[1]

CMV is a member of the virus family herpesviridae and is the most common congenital intrauterine infection.[3] cCMV is caused when a mother is infected with CMV in pregnancy and passes it to her unborn baby.[1] The risk of severe disease is greatest if the mother is infected in early pregnancy; most have no symptoms.[2] Diagnosis is by tests in the first 3-weeks after birth; on preferably urine, although saliva and blood can be used.[1][2] The chance of infection is reduced by hand washing, and avoiding touching saliva or urine of very young children.[1]
Worldwide the condition is common, and likely underreported.[4]
