2012年山东省疟疾疫情流行病学特征分析

Epidemiological analysis of malaria prevalence in Shandong Province in 2012

目的分析2012年山东省疟疾疫情及流行特征,为该省消除疟疾提供参考依据。方法从中国疾病预防控制中心疾病监测信息报告管理系统收集山东省疟疾个案流行病学调查资料,采用描述流行病学方法分析2012年山东省疟疾流行病学特征。结果2012年山东省共报告疟疾93例,年发病率0.097/10万,比2011年下降19.83%。报告的93例疟疾病例均为输入性病例,较2011年的97例下降了4.12%;首年度实现了无本地感染病例。报告病例较多的为济宁、青岛和威海3市,病例数占全省总病例数的62.37%(58/93)。93.55%的疟疾病例为非洲输入性病例,大部分来自赤道几内亚、尼日利亚、安哥拉。首次报告输入性卵形疟3例。结论2012年山东省无本地疟疾病例报告,但输入性疟疾防控形势不容乐观。需继续加强疫情管理,加强专业人员培训及工作督导,加强流动人口管理、宣传和检测,探索多部门协调机制。
