摘要
目的 分析贵州省残存嗜人按蚊地区疟疾发病特点及流行规律 ,为制定疟疾防治及监测方案提供科学依据。 方法 收集分布区 1999～ 2 0 0 1年疟疾发病及病例侦察情况 ,用流行病学方法分析疟疾病人及疫点类型 ,疫点平均病例数等流行病学特点。 结果 嗜人按蚊疟区发病率仍超过 1 ,发热病人血检阳性率为 0 .2 5 % ,流动人群血检阳性率为1.31% ,当地感染疟疾病例占病例总数的 84 .5 9% ,输入性病例占 15 .4 1% ,内源性疫点占 87.2 3% ,外源性疫点占12 .77% ,平均疫点病例数为 1.30例。 结论 嗜人按蚊疟区是现阶段主要疟疾高发流行区 ,发现病人的主要手段仍是对当地发热病人的血检 ,以本地病例和内源性疫点为主 ,发病比较散发 ,呈点状分布。
Objective To analyze epidemiological characteristics of malaria in Anopheles anthropophagus distribution areas in Guizhou Province so as to provide scientific proof for formulating of malaria control measure. Methods The data on malaria incidence and cases in An. anthropophagus distribution area from 1999 to 2001 in Guizhou Province was collected. The epidemiological method was used to analyze the classification of malaria cases and focus, average No. of cases in each malaria focus, etc. Results The malaria incidence in the areas was still over 1. The positive rates of blood examination were 0.25% and 1.31% in the fever patients and mobile population respectively. The local and imported cases accounted for 84.59% and 15.41% of the total patients respectively. The local malaria focus accounted for 87.23% of the total foci. The average cases were 1.30 in the each malaria focus. Conclusion The An. anthropophagus distribution areas were still malaria endemic seriously areas in Guizhou Province. Now, the major way finding malaria cases was blood examination in the local fever patients. Malaria cases distribution was sporadic. The local malaria cases and foci were advantage compared with imported malaria cases and foci.
