1995～2004年广西疟疾监测措施与防治效果

目的分析广西壮族自治区1995~2004年疟疾监测结果,评价监测措施,为制定疟疾防治对策提供科学依据。方法收集1995~2004年广西区92个县(市)当地居民发热病人、病灶点居民和流动人口监测资料进行描述和分析。结果10年间全区92个县(市)共血检当地发热病人1092万人次,病灶点居民42.7万人次,外出回归人群24.6万人次,外来人群25.4万人次,4类人群血检阳性率分别为0.009%、0.079%、1.386%和0.324%,共检出疟疾病例5517例,本地感染病例占总病例的23.29%(1285/5517),输入性病例占76.71%(4232/5517)。结论广西区连续17年疟疾发病率控制在1/万以下,当地感染病例少,输入性疟疾病例多、分布面广、高度分散,但输入继发病例发生率较低,现行疟疾监测与防治措施能有效监控疟疾流行动态。

Evaluation on effect of malaria surveillance and control in Guangxi from 1995 to 2004

Objective To analyze the effect of malaria surveillance and evaluate the surveillance measure in Guangxi Zhuang Autonomous Region from 1995 to 2004 so as to provide scientific basis for formulating control strategy at the late-stage of malaria control. Methods The data on blood smear examination of febrile patients among local residents, focus residents and mobile population in 92 counties from 1995 to 2004 were collected,described and analyzed. Results The totals of 10920395,427600,246159 and 253530 slides in local residents,focus residents, returned population and endemic population were examined. The average positive rates of blood examination were 0.009%,0.079%,1.386% and 0.324%,respectively. The indigenous cases and imported cases accounted for 23.29% (1285/5517) and 76.71% (4232/5517) of the total malaria cases respectively. Conclusions The malaria incidence in Guangxi Zhuang Autonomous Region has been under 1/10000 for 17 years. There is less indigenous malaria in Guangxi. The imported malaria cases are dominated and scattered in whole Region. The secondary cases of imported malaria is very low. The results show that the present surveillance system and control programs are effective for monitoring the epidemic situation of malaria.
