A survey of children born between 1949 and 1980 who are known to have been fitted with hearing aids in Australia by the age of 18 years reveals a ratio of 2.605 cases for every 1000 liver births. This incidence of childhood deafness is higher than previously reported, as a result of the greater number of birth years considered. Approximately 41.2% of these children have severe or profound deafness. A history of maternal rubella was reported in 11.06% of cases, but a significant reduction in the number of reported rubella cases after 1976 has led to correspondingly fewer diagnoses of severely and profoundly deaf children.
一项针对1949年至1980年间出生、在澳大利亚18岁前已知佩戴助听器的儿童的调查显示，每1000例活产中有2.605例。由于考虑的出生年份更多，儿童期耳聋的发病率高于先前报告的水平。这些儿童中约41.2%患有重度或极重度耳聋。11.06%的病例报告有母亲风疹病史，但1976年后报告的风疹病例数量显著减少，导致相应地被诊断为重度和极重度耳聋儿童的数量减少。
