Congenital CMV Hearing Loss
Cytomegalovirus, or CMV, is the most common infectious cause of birth defects in the United States. About 1 out of 200 babies are 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.
Some babies with signs of congenital CMV at birth may benefit from medicines.
Some babies with signs of congenital CMV at birth may benefit from medicines. Babies who show signs of congenital CMV disease can be treated with medicines called antivirals. Antivirals may decrease the severity of hearing loss. Babies who get treated with antivirals should be closely watched by their doctor because of possible side effects.
Hearing loss can be present at birth or develop later.
Babies with congenital CMV may have hearing loss in one ear and may later develop hearing loss in the other ear. Progression may occur through adolescence.
Children with hearing loss can benefit from services.
Children diagnosed with hearing loss should receive services such as speech or occupational therapy. These services help ensure they develop important communication, language, and social skills. Children with hearing loss can also learn other ways to communicate, such as using sign language, and to use devices such as hearing aids and cochlear implants. The earlier children with hearing loss start receiving services, the more likely they are to reach their full potential.
