摘要:

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%(215/1 450 957)、0.0015%(12/811 810)和0(0/276 859);外出回归人群阳性率分别为3.1532%(360/11 417)、2.0206%(290/14 352)和0.2865%(424/148 008);外来人群血检阳性率为0.1710%(85/49 699)、0.1955%(31/15 860)和0.0899%(70/77 856)。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%(102/33 134)、0.2392%(69/28 843)和0.0283%(37/130 828)。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。

Abstract:

Objective To compare and analyze the monitoring results of three different types of malaria in the corresponding endemic areas in Guangxi Zhuang Autonomous Region (Guangxi) from 1999 to 2008, so as to evaluate the monitoring measures and provide the basis for category control and prevention. Methods Fever cases of local residents, floating population and indirect immunofluorescence antibody (IFA) assay results in 51 counties within the endemic areas of three different patterns of malaria in Guangxi from 1999 to 2008 were collected for descriptive analysis. Results The plasmodium positive rate in the blood of local fever patients in the three kinds of malaria-endemic area (12 counties on the Guizhou-Guangxi border, 8 counties on the Sino- Vietnamese border and 31 malaria-free counties) were 0.0148% (215/1 450 957), 0.0015% (12/811 810) and 0 (0/276 859), respectively; the positive rate of returned emigrants were 3.1532% (360/11 417), 2.0206% (290/14 352) and 0.2865% (424/148 008), respectively; and the those of immigrants were 0.1710% (85/49 699), 0.1955% (31/15 860) and 0.0899% (70/77 856), respectively. A total of 1487 cases of malaria were detected; local infected patients accounted for 15.27% (227/1487), returned emigrant patients accounted for 72.23% (1074/1487), and immigrant patients accounted for 12.51% (186/1487). The IFA positive rates for the focal groups in the three patterns of malaria-endemic area were 0.3078% (102/33 134), 0.2392% (69/28 843) and 0.0283% (37/130 828), respectively. Conclusion The annual incidence in the endemic areas of three patterns of malaria in Guangxi was controlled below one per ten thousand. The local transmitted cases were concentrated mostly in the 12 counties on the Guizhou-Guangxi border and the 8 counties on the Sino-Vietnamese border, whereas no cases were found in the 31 malaria-free counties. The antibody levels of the population were consistent with the degree of malaria prevalence. Therefore, the monitoring and control of the three patterns of malaria in the corresponding endemic areas should be further strengthened.
