1950 - 2007年内蒙古自治区流行性乙型脑炎流行病学特征分析

Epidemiology of Japanese encephalitis in Inner Mongolia, 1950 - 2007

  • 摘要: 目的 分析内蒙古自治区(内蒙古)流行性乙型脑炎(乙脑)的流行情况,为有效预防控制乙脑提供科学依据。 方法 采用描述性流行病学现况分析方法,对1950 - 2007年内蒙古乙脑报告病例做回顾性分析。 结果 1950 - 2007年间内蒙古共报告乙脑病例4850例,年平均发病率为0.49/10万, 1969-1984年为内蒙古乙脑高流行时期,报告乙脑病例数4297例,年平均发病率为1.55/10万, 1985 - 2007年乙脑报告病例数为412例,年平均发病率为0.08/10万,特别是进入2000年后,2000 - 2007年乙脑报告病例数显著减少,为26例,年均发病率仅为0.01/10万,每年乙脑报告病例数低于10例。赤峰和通辽市在58年间共报告乙脑病例4117例,占内蒙古乙脑报告病例总数84.89%。 结论 近20年来内蒙古乙脑呈低水平流行,发病具有一定地域性,赤峰和通辽市为内蒙古乙脑高发地区。

     

    Abstract: Objective To understand the epidemiological characteristics of Japanese encephalitis (JE) in Inner Mongolia and provide scientific evidence for the effective control and prevention of JE. Methods Descriptive epidemiological analysis was conducted on reported JE cases in Inner Mongolia from 1950 to 2007. Results During 1950 - 2007, a total of 4850 cases of JE were reported to occur in Inner Mongolia with the average annual incidence rate of 0.49/lakh. Most cases (4297 cases) were reported during 1969-1984, and the average annual incidence rate was 1.55/lakh. However the average annual incidence rate from 1985 to 2007 was 0.08/lakh (412 cases), which was lower than national level. Only 26 cases had been reported since 2000 with the average annual incidence rate of 0.01/lakh. The JE cases occurred in Chifeng and Tongliao (4117 cases) accounted for 84.89% of the total cases. Conclusion The JE incidence declined in Inner Mongolia in recent 20 years. Chifeng and Tongliao were the areas with high incidence of JE.
