To estimate the annual prevalence of viral and other neurological infections at large hospitals in Japan during the period from 1989 to 1991.
A nationwide questionnaire survey on the numbers of inpatients with viral and other neurological infections was sent for completion to the chiefs of Departments of Internal Medicine, Neurology and Pediatrics at all hospitals with more than 200 beds.
The average annual number of inpatients (and the number per 10(6) population) with encephalitis in large hospitals was estimated to be 2,200+/-400 (17.7+/-3.2), while it was 32,000+/-16,000 (258+/-129) for meningitis, and 650+/-50 (5.2+/-0.4) for myelitis. Among the inpatients with encephalitis, meningitis, and myelitis, an unknown etiology was the most common (51.2% in encephalitis, 73.2% in meningitis, and 36.3% in myelitis), followed by a viral etiology for all three diseases.
The first estimate was made of the annual prevalence of viral and other neurological infections and their etiology in Japan.
估算1989年至1991年期间日本大型医院病毒性及其他神经系统感染的年患病率。
向所有床位超过200张的医院的内科、神经科和儿科主任发送了一份关于病毒性及其他神经系统感染住院患者数量的全国性问卷调查，以完成调查。
大型医院中，脑炎住院患者的年平均数量（及每10^6人口中的数量）估计为2200±400（17.7±3.2），而脑膜炎为32000±16000（258±129），脊髓炎为650±50（5.2±0.4）。在脑炎、脑膜炎和脊髓炎住院患者中，病因不明最为常见（脑炎中占51.2%，脑膜炎中占73.2%，脊髓炎中占36.3%），其次是这三种疾病均由病毒引起。
首次对日本病毒性及其他神经系统感染的年患病率及其病因进行了估算。
