Congenital CMV, or congenital cytomegalovirus, is a viral infection that a baby can acquire before birth. It occurs when a pregnant person passes the CMV virus to their developing fetus, often without showing any symptoms. This can lead to various health issues for the baby, including hearing loss, vision problems, and developmental delays. Most babies born with congenital CMV appear healthy at birth, but some may develop symptoms later. Early diagnosis and intervention are crucial for managing the effects of the virus. Regular check-ups and screenings can help identify any potential complications, ensuring the best possible outcomes for affected children.
