Although CMV can be isolated from lu In the United States, cytomegalovirus is the most common congenital viral infection and the number 1 cause of nonhereditary sensorineural hearing loss. The hallmark of CMV infection is the finding of intranuclear inclusions consistent with herpesvirus infection. The vast majority of infants may be asymptomatic, especially if cytomegalovirus is contracted later in the pregnancy, and some symptoms may have a delayed onset. Histological findings may reveal CMV inclusions if supplementary testing is requested, which can aid diagnosis. Abstract Cytomegalovirus (CMV) causes clinically significant gastrointestinal (GI) injury.
