广西1995-2004年输入性疟疾监测与防治

Surveillance and control of imported malaria in Guangxi Region from 1995 to 2004.

目的分析广西壮族自治区1995-2004年输入性疟疾监测和控制结果,评价输入性疟痰对疟防工作的影响,为疟疾防治后期监测提供科学依据。方法收集1995-2004年广西全区92个市、县当地居民发热病人、病灶点居民和流动人口监测资料进行回顾性分析。结果10年间全区当地居民发热病人、病灶点居民血栓阳性率为0.009%、0.049%,外出回归和外来人口血栓阳性率为1.39%、0.32%,本地感染病例占总病例的21.22%(1140/5372),输入性病例占78.78%(4232/5372)。结论广西连续17年疟疾发病率控制在1/万以下,输入性疟疾病例数最多、分布面广、高度分散,但传播指数较低,输入性疟疾监测与防治措施得当。

Objective To analyze the result of imported malaria surveillance and control, to evaluate imported malaria affect malaria eontrel in Guangxi from 1995 to 2004 . So as to provide scientific basis for malaria surveillance at the late - stage of malaria eontrel. 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 and analyzed. Results The average positive rates of blood examination were 0.009% , 0.049% , 1.39% and 0.32% in the febrile patients of local residents, focus residents ,returned population and moved in population respectively. The indigenous eases and imported eases accounted for 21.22% （1 140/5 372） and 78.78% （4 232/5 372） of the total malaria eases respectively. Conclusion The malaria incidence in Guangxi province was under 1/10000 for 17 years. The imported malaria eases was dominated and scattered in whole province. The transmission index of imported malaria was very low. The results showed the measure for imported malaria surveillance and eontrel is effective.
