Universal screening for congenital cytomegalovirus (CMV) in newborns, using dried blood spot analysis during the first week of life, created opportunities to intervene for improved outcomes, a diagnostic study has shown.
Congenital CMV is the most common nongenetic cause of hearing loss in children and a leading cause of other neurologic disabilities. Without universal screening, infants who are asymptomatic for the virus are especially at risk for congenital CMV-related sequelae later in life, claimed the study’s authors in JAMA Network Open. https://bit.ly/45PNwml
