Congenital CMV infection occurs when the cytomegalovirus is transmitted from a pregnant person to their baby during pregnancy. This can happen during pregnancy, at birth, or through breastfeeding. Many babies with congenital CMV may not show symptoms at birth, but some can develop health issues later. Symptoms of congenital CMV infection can include hearing loss, vision problems, and developmental delays. Early diagnosis and intervention are important for managing these potential complications. Regular check-ups and screenings can help identify and address any issues that arise as the child grows.
