黔东南州2004年106例流行性乙型脑炎流行特征分析

Epidemic Features Analysis of 106 Cases of Epidemic Encephalitis Type B in Qiandongnan Prefecture of Guizhou Province in 2004

  • 摘要: 目的对黔东南州2004年流行性乙型脑炎流行病学特征进行分析,为预防和控制乙型脑炎提供科学依据。方法采用统一个案调查表,对辖区内乙脑报告病例进行调查;通过MicrosoftExcel建立病例数据库,运用描述流行病学方法对病例进行分析。运用EIA检测急性期病人血清中的抗乙脑IgM抗体。结果全州报告的106例乙脑病例,90.57%发生在农村,88.68%的发病村寨近三年没有接种过乙脑疫苗,0 ̄9岁儿童接种率为14.66%,≤9岁儿童发病91例,占85.85%。在所采的28份血清中抗乙脑IgM抗体阳性率为78.57%。结论黔东南州乙型脑炎具有严格的季节性和年龄特征,农村卫生条件差,适宜蚊虫孳生,免疫接种率低,为引起流行主要原因,建议加强农村乙脑疫苗预防接种工作,把乙脑疫苗纳入儿童计划免疫。络直报工作。

     

    Abstract: Objective The epidemic features of epidemic encephalitis type B in Qiandongnan Prefecture of Guzhou Province in 2004 were analyzed to provide scientific evidence for the control and prevention of encephalitis type B.Methods Questionnaires were adopted to survey the re-ported encephalitis type B cases in the responsible area.Case database was established with the aid of Microsoft Excel and was analyzed by applying the descriptive epidemiology method.EIA was employed to test the anti encephalitis type B antibody IgM in the serum for the patients in acute stage.Results Of the 106 cases infected with encephalitis type B reported in the whole prefecture,90.57% occurred in countries and 88.68% of the countries were not inoculated with encephalitis type B vaccine in the recent 3 years.The immunization rate of children among ages of 0 to 9 was 14.66% and there were 91 children under the age of 9 infected with the diseases,accounting for 85.85% of all infected patients.Of the 28 serum samples,the positive rate of the anti-encephalitis type B antibody IgM was 78.57%.Conclusion In Qiandongnan Prefecture of Guizhou Province,encephalitis type B displayed a strict seasonal mode with an age characteristic.The main reason for the epidemic was the poor sanitation condition,which was suitable for the reproduction of mosquitoes and other insects,and the low immunization rate.It is recommended to enhance the inoculation of encephalitis type B vaccine in the countries and to involve encephalitis type B into the children'S expanded program on immunization.
