目的了解2008年乙脑病例流行病学分布情况,为制定乙脑防控策略提供科学依据。方法根据监测病例定义,进行报告、个案调查,采集血和脑脊液标本进行实验室诊断。采用贝西公司生产的试剂盒检测病例标本的乙脑IgM抗体,评价标准按照使用说明书;采用Excel软件进行统计分析。结果2008年监测病例报告率比2005年增加了1.14%;血标本采集率99.2%,脑脊液标本采集率27.5%,确诊病例数22例,发病率0.26/10万,与往年发病率持平,略有升高。无暴发疫情,部分县发病数较往年增加,发病高峰在6月上旬,年龄主要集中在3～6岁。结论2008年乙脑监测系统运行情况正常,为针对不同地区,不同人群制定免疫措施提供了科学依据,同时将监测数据经过网络直报上报给国家。
Objective To understand the epidemiological distribution of Japanese encephalitis in 2008 and provide a scientific basis for the prevention and control of Japanese encephalitis. Methods According to the definition of surveillance cases, reports, case studies, blood and cerebrospinal fluid samples were collected for laboratory diagnosis. The samples produced by Bessie’s kit were used to detect the IgM antibodies of JEBB in accordance with the instruction manual. The software was used for statistical analysis. Results The reported rate of surveillance cases in 2008 increased by 1.14% compared with that of 2005; the blood sample collection rate was 99.2%; the cerebrospinal fluid sample collection rate was 27.5%; the number of confirmed cases was 22 cases, the incidence rate was 0.26 / 100,000, with the same incidence in previous years Rise. No outbreaks, the incidence of some counties increased over previous years, the peak incidence in early June, the age mainly concentrated in 3 to 6 years old. Conclusion The monitoring system of Japanese encephalitis in 2008 is in normal operation, which provides a scientific basis for formulating immunization measures in different regions and different populations. At the same time, the monitoring data are reported to the country directly through the network.
