本文对虫媒病毒作为我国病毒性脑炎病原的作用进行了血清流行病学研究。1988～1990年在我国15个地区搜集了614例疑似病毒性脑炎病例的急性期和恢复期血清;对3种主要虫媒病毒群(黄病毒群、甲群、加里福尼亚(CAL)血清群病毒)抗原的血凝抑制(HI)抗体进行了测定,结果大部分地区的病例双份血清对黄病毒群和甲群虫媒病毒 HI 的滴度呈4倍升高。未发现对 CAL 病毒群中的 SSH 病毒HI 滴度呈4倍升高的病例。甲群虫媒病毒感染病例的年龄为50天～32岁。黄病毒感染的病例年龄为6个月～50岁。严重的中枢神经系统症状在黄病毒感染病例中较多。本研究肯定了黄病毒作为我国病毒性脑炎病原的重要性。并提供了在我国可能存在1种或1种以上可引起神经症状的甲群虫媒病毒感染的证据,并阐述了甲群虫媒病毒症状性感染在我国地理分布的概貌。
In this paper, the serological epidemiological study on the role of arbovirus as the etiological agent of viral encephalitis in our country. A total of 614 acute and convalescent sera from 614 cases of suspected viral encephalitis were collected in 15 districts of China from 1988 to 1990. The three major arboviruses (flavivirus, group A, CAL) Serogroup virus) antigen hemagglutination inhibition (HI) antibody was measured, the results of most parts of the two cases of serum sera of flaviviruses and flavivirus HI HI showed a four-fold increase. No case of 4-fold increase in HI titer of the SSH virus in the CAL virus population was found. A group of Arbovirus infection age of 50 days to 32 years. The age of cases of flavivirus infection is 6 months to 50 years. Serious CNS symptoms are more common in cases of flavivirus infection. This study affirmed the importance of flavivirus as a pathogen of viral encephalitis in our country. And provides evidence that there may be one or more CNGV-like infections that may cause neurological symptoms in China, and an overview of the geographical distribution of CNG Syndrome infection in China.
