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 analyze the malaria epidemic characteristics in Xiaoshan district since the malaria elimination was launched in 2010-2014, evaluate the effectiveness of malaria elimination work, and provide the basis for the formulation of malaria control measures suitable for the actual situation in this area. Methods The disease surveillance information reporting management system of China Center for Disease Control and Prevention and the malaria epidemic situation questionnaire were used to collect malaria epidemic data of Xiaoshan District from 2010 to 2014 and statistical analysis was made with Excel 2003. Results A total of 25 cases of malaria were reported from Xiaoshan district in 2010-2014. The annual incidence of malaria was between 0.09 ~ 0.38 / 100 000. The surveillance reports were all laboratory confirmed cases, of which, malaria accounted for 48.00% (12 cases) and falciparum malaria accounted for 52.00% (13 cases), with no deaths. The majority of patients were young adults, mainly overseas workers or businessmen. There were 8 imported cases and 17 imported cases abroad, accounting for 32.00% and 68.00% respectively. There were no reports of local infection cases. Conclusion The morbidity of malaria in Xiaoshan District has been kept at a relatively low level. The source of infection has shifted from the combination of extra-provincial infection and extra-national infection to overseas infection. In the future, it is necessary to strengthen the monitoring and disposal of outbreaks of imported malaria abroad.
