Hearing Outcome and Virologic Characteristics of Children With Congenital Cytomegalovirus Infection in Relation to Antiviral Therapy: A Retrospective Cohort Study.

Background: Congenital cytomegalovirus infection is one of the leading causes of nongenetic sensorineural hearing loss. The aim of our retrospective cohort study was to describe the changes in hearing in relation to antiviral therapy and the trend in viremia and viruria in children with congenital cytomegalovirus infection.
