False-colour transmission electron micrograph (TEM) of a single virion (virus particle) of cytomegalovirus, showing the central protein capsid (orange - contains viral genetic code in form of DNA) surrounded by a large lipoprotein envelope (green). Cytomegalovirus , a member of the herpesvirus group, causes a condition among newborns called cytomegalic disease, characterized by jaundice & an enlarged liver & spleen. It is transmitted to the infant by the mother either while in womb or during birth. The virus earned its name cytomegalo, meaning large cell, from the swollen appearance of an infected cell.
