目的比较和分析广西壮族自治区(广西区)3类不同疟疾流行区1999-2008年疟疾监测结果,评价监测措施,为分类防治提供科学依据。方法收集1999-2008年广西区3类不同疟区51个县(市)当地居民发热病例、流动人口和间接免疫荧光抗体(IFA)检测资料进行描述和分析。结果 10年间黔桂交界地区12个县、中越边境地区8个县和消除疟疾地区的31个县3类疟区当地居民发热病例血检阳性率分别为0.0148%(215/1450957)、0.0015%(12/811810)和0(0/276859);外出回归人群阳性率分别为3.1532%(360/11417)、2.0206%(290/14352)和0.2865%(424/148008);外来人群血检阳性率为0.1710%(85/49699)、0.1955%(31/15860)和0.0899%(70/77856)。共检出疟疾病例1487例,本地感染病例占总病例数的15.27%(227/1487),外出回归感染病例占72.23%(1074/1487),外来病例占12.51%(186/1487)。3类疟区重点人群IFA检测抗体阳性率分别为0.3078%(102/33134)、0.2392%(69/28843)和0.0283%(37/130828)。结论广西区3类疟区疟疾年发病率控制在1/万以下,当地传播病例主要集中在黔桂交界12个县和中越边境8个县,消除疟疾的31个县无病例分布,人群抗体水平与疟疾流行程度相一致。应继续加强对3类不同疟疾流行区的监测及控制。
Objective To compare and analyze the results of malaria surveillance in three different malaria endemic areas of Guangxi Zhuang Autonomous Region (Guangxi Region) from 1999 to 2008, evaluate the monitoring measures, and provide a scientific basis for classification and prevention. Methods The cases of fever, the floating population and indirect immunofluorescence antibody (IFA) test data from 51 counties (cities) in three different malaria areas of Guangxi during 1999-2008 were collected and analyzed. Results The positive rates of blood tests for fever among local residents in 3 malaria endemic areas of 12 counties in the border area of Guizhou and Guangxi and 8 counties in the border areas of China and Vietnam and 31 counties in the malaria elimination area were 0.0148% (215/1450957) and 0.0015% 12/811810) and 0 (0/276859) respectively. The positive rates of return to the population were 3.1532% (360/11417), 2.0206% (290/14352) and 0.2865% (424/148008) 0.1710% (85/49699), 0.1955% (31/15860) and 0.0899% (70/77856). A total of 1487 cases of malaria were detected, accounting for 15.27% (227/1487) of the total number of cases of local infection, 72.23% (1074/1487) of returning to the infected cases and 12.51% (186/1487) of the foreign cases. The positive rates of IFA detection antibody in the major population of 3 malaria areas were 0.3078% (102/33134), 0.2392% (69/28843) and 0.0283% (37/130828) respectively. Conclusion The annual incidence of malaria in the three malaria-endemic areas in Guangxi is controlled below 1 / 10,000. The local transmission cases are mainly concentrated in 12 counties at the border between Guizhou and Guangxi and 8 counties along the border between China and Vietnam. There is no case distribution in 31 counties with malaria elimination. The population antibody level In line with the prevalence of malaria. Monitoring and control of three different malaria-endemic areas should continue to be strengthened.
