目的分析泉州市1963-2009年流行性乙型脑炎(乙脑)流行病学特征,为有效控制乙脑提供科学依据。方法对乙脑发病资料进行描述流行病学分析。结果泉州市1963-2009年乙脑发病率呈下降趋势;自2005年起山区县发病率高于沿海县;1990-2009年发病高峰季节前移1个月;2005-2009年10岁以下儿童所占比例比往年下降50%;调查的乙脑病例中无免疫史的占50%。结论泉州市乙脑发病率从60年代的34.93/10万下降至目前的0.08/10万,表明乙脑预防控制取得了显著成效,但仍需继续提高乙脑疫苗的接种率,开展乙脑病例监测,在流动人口聚集地、边远山区、免疫规划薄弱的乡镇进行重点控制是有效预防乙脑的发生和流行的必要措施。
Objective To analyze the epidemiological characteristics of Japanese encephalitis (JE) from 1963 to 2009 in Quanzhou and provide a scientific basis for the effective control of JE. Methods Descriptive epidemiological analysis of Japanese encephalitis data. Results The incidence of Japanese encephalitis decreased from 1963 to 2009 in Quanzhou. The incidence in mountainous counties was higher than that in coastal counties since 2005. The incidence of encephalitis in the peak season of 1990-2009 was one month. In 2005-2009, Accounting for 50% less than in previous years; 50% of those without JE have been investigated. Conclusions The incidence of Japanese encephalitis in Quanzhou dropped from 34.93 / 100000 in the 1960s to 0.08 / 100000 at present, indicating that the prevention and control of encephalitis has achieved remarkable results. However, the vaccination rate of Japanese encephalitis vaccines needs to be further increased, and cases of Japanese encephalitis Monitoring and controlling key towns and villages with floating population centers, remote mountainous areas and poor immunization programs are necessary measures for effectively preventing the occurrence and prevalence of JE.
