目的分析广西残存嗜人按蚊分布区近10年疟疾发病特点、监测结果及其评价,为疟疾防治后期的监测与控制提供科学依据.方法收集2000-2009年广西嗜人按蚊分布区15个县(市)当地居民发热患者、外出回归农民工、外来人员的疟疾监测资料,分析疟疾感染率和病例分布,对媒介和间接免疫荧光法(indirect immunofluorescence assay,IFA)检测资料进行描述和分析.结果嗜人按蚊分布区15县共血检常住居民发热患者152.50万人次,病灶点居民5.85万人次,外出回归农民工3.82万人次,外来人口5.45万人次,4类人群血检阳性率依次为0.0079%(120/1 525 031)、0(0/58 502)、0.6902%(264/38 252)和0.1926%(105/54 516);共检出疟疾患者489例,本地感染病例占24.52%(120/489),外出回归感染病例占53.99%(264/489),外来病例占21.47%(105/489).环江县嗜人按蚊占按蚊总数的3.32%(227/6 832),重点人群IFA检测抗体阳性率为0.092%(49/53 112).结论广西嗜人按蚊分布区疟疾发病率控制在1/万以下,当地传播病例主要分布在环江、南丹、融水、三江和上思等5县,输入性病例15县均有分布.人群抗体水平与疟疾流行程度一致.

Objective To analyze the results of malaria surveillance in Anopheles anthropophagus distribution zone of Guangxi Zhuang Autonomous Region during 2000-2009 so as to provide scientific basis for malaria surveillance at the late-stage of malaria control. Methods The data on blood smear examination of febrile patients among local residents, returned peasant-workers, immigrated population, vector and indirect immunofluorescence assay(IFA) surveillance data in 15 counties of An. anthropophagus distribution zones from 2000 to 2009 were collected,described and analyzed. Results 1 525 031 slides of febrile patients in local residents,58 502 slides of focus residents,38 252 slides in returned peasant-workers and 54 516 slides in immigrated population were examined from 2000 to 2009. The average positive rates of blood examination were 0. 0079% ,0,0.6902% and 0. 1962% in febrile patients,focus residents, returned peasant workers and immigrated population respectively. The total of 489 malaria cases was detected. The indigenous cases,imported cases in returned peasant-workers or in immigrated population accounted were 24.52% (120/489), 53.99%(264/489) and 21.47% (105/489) ,respectively. Population of An. anthropophagus accounted for 3.32%(227/6 832) of the total Anopheles vectors in Huanjiang County. The positive rate of IFA in focus residents was 0.092%(49/53 112). Conclusion The malaria incidence in 15 counties of An. anthropophagus distribution zone was under 1/10 000. The indigenous malaria cases were mainly distributed in Huanjiang, Nandan,Rongshui,Sanjiang and Shangsi counties. Imported malaria cases were scattered in 15 counties. The level of malaria antibody in population was coincident with malaria epidemical situation in this area.
