      Data Source: 2020 CDC Early Hearing Detection and Intervention (EHDI) Hearing Screening & Follow-up Survey (HSFS)

      Background: The CDC’s National Center on Birth Defects and Developmental Disabilities promotes the health of babies, children, and adults, with a focus on preventing birth defects and developmental disabilities and optimizing the health outcomes of those with disabilities. As part of these efforts, the Center is actively involved in addressing the early identification of permanent hearing loss among newborns and infants. Hearing loss affects between 1 and 2 per 1,000 infants in the United States and, when left undetected, can delay a child’s speech and language, social, and emotional development.

      To ensure children with permanent hearing loss are identified as soon as possible, states and territories have implemented Early Hearing Detection and Intervention (EHDI) programs. These EHDI programs work to ensure all infants are screened for hearing loss, ideally before 1 month of age; receive diagnostic audiologic evaluation (for those not passing the screening), ideally before 3 months of age; and are enrolled in early intervention (for those identified with permanent hearing loss), ideally before 6 months of age. The Hearing Screening & Follow-up Survey is a voluntary survey sent out annually by CDC to each state and territorial EHDI program that requests non-estimated hearing screening, diagnostic, and intervention information on infants born in a specified calendar year (e.g., 2020). The survey helps to assess the progress of EHDI efforts to identify infants with permanent hearing loss across the United States. This summary of the 2020 HSFS highlights EHDI-related information for babies born between January 1, 2020 and December 31, 2020.
