Congenital Cytomegalovirus (cCMV) is the most common infectious cause of birth defects in the United States. About 1 out of 200 babies is born with congenital CMV.
One out of 5 babies with congenital CMV will have symptoms or long-term health problems, such as hearing loss. Hearing loss may progress from mild to severe during the first two years of life, which is a critical period for language learning. Over time, hearing loss can affect your child’s ability to develop communication, language, and social skills.
