Congenital Cytomegalovirus and Deafness.

Although the incidence of medical and neurological problems resulting from congenital cytomegalovirus (CMV) infection is relatively low, the widespread and indiscriminate nature of this infection and the severity of these conditions when they do occur are such that it warrants the close attention of medical specialists, audiologists, and educators. The identification of congenital CMV is especially difficult because of its largely nonsymptomatic character, and because conditions associated with it, including hearing impairment, can be either progressive in nature or occur only later in life. Data reviewed in this study resemble those reported for children with impaired hearing from the 1964-65 maternal rubella epidemic: hearing loss in the severe to profound range, often accompanied by serious additional disabilities, especially mental retardation and cerebral palsy. Depressed achievement test results of children with CMV-induced hearing loss are further indications of the serious nature of this disease.The presence of any symptoms of CMV infection in infants or of risk factors associated with it-e.g., purplish skin rash, severe asphyxia, jaundice, low birth weight, swollen lymph glands, and other mononucleosis-like symptoms-signals the need for immediate testing, including audiological evaluation, and, if results are positive, the initiation of early medical and educational intervention.

Hearing-impaired children under age 6: a demographic analysis.

This paper presents information about hearing-impaired children under the age of 6 who are receiving special educational services in the United States and have been reported to the Annual Survey of Hearing-Impaired Children and Youth conducted by Gallaudet University's Center for Assessment and Demographic Studies. Results indicate an increase in the number of hearing-impaired children under age 6 reported to the survey over the last 10 years, especially children from minority backgrounds. The second section of the analysis focuses on students from schools participating in a model state project that encourages early identification and provision of services to hearing-impaired students and their families. The data pertain only to those children who are receiving services through established programs reporting to the Annual Survey; thus, inferences about the overall prevalence of hearing impairment among this age group should not be drawn.
