目的 分析2010-2014年启动消除疟疾行动以来萧山区疟疾流行特征，评价消除疟疾工作效果，为制定适合本区实际的疟疾防治措施提供依据。 方法 利用中国疾病预防控制中心疾病监测信息报告管理系统以及疟疾疫情个案调查表，收集2010-2014年萧山区疟疾疫情数据资料，用Excel 2003进行统计分析。 结果 2010-2014年萧山区共监测报告疟疾病例25例，年报告发病率在（0.09 ~ 0.38）/10万之间。监测报告病例均为实验室确诊病例，其中间日疟占48.00%（12例），恶性疟占52.00%（13例），无死亡病例发生。患者以青壮年为主，主要为境外务工或经商人员；国内省外输入性病例8例，境外输入性病例17例，分别占32.00%和68.00%，无本地感染病例报告。 结论 萧山区疟疾发病率继续保持在较低水平，感染来源已从省外感染和境外感染结合为主转向境外感染。今后需加强境外输入性疟疾疫情的监测和处置。

Objective To understand the malaria epidemic situation and characteristics in Xiaoshan District， 2010-2014， so as to provide the evidence for formulating effective malaria elimination strategies and measures. Methods The reported malaria cases from the Internet Reporting System and the epidemiological data of malaria in Xiaoshan District were collected and analyzed statistically with Excel 2003. Results From 2010 to 2014， 25 malaria patients were reported， and the annual incidences were in the range of 0.09/100 000-0.38/100 000. All the cases were confirmed by laboratory examinations. Among these cases， 12 （48.00%） were vivax malaria cases and 13 （52.00%） were falciparum malaria cases. There was no death. These patients were mainly young people who were workers or businessmen overseas. There were 17 （68.00%） abroad?imported cases and 8 （32.00%） domestic?mobile cases， but no local malaria cases. Conclusions Malaria incidence rate continues at a lower level in Xiaoshan District. Since starting the action of malaria elimination， the source of infection has turned from domestic?mobile cases to abroad?imported cases. Therefore， in the future， we should enhance the prevention and control measures to reduce the risk of overseas imported malaria.
