摘要
目的 了解贵州省不同媒介地区现阶段疟疾传播的流行病学特点。方法 将全省疟区按主要传疟媒介划分为中华按蚊流行区、嗜人按蚊流行区和微小按蚊流行区，根据近五年的疟疾监测资料，分别对不同地区的疟疾流行态势进行流行病学分析。结果嗜人按蚊区发病率，为４．２７１万，以本地感染病例为主，占病例总数的８３．８１％，血检阳性率为０．４９％，病灶点以内源灶点为主，中华按蚊区发病率为０．４６／万，以输入性病例为主，占总病例的８８．０７％，血检阳性率为０．０４％，病灶点多为外源性灶点；微小按蚊区介于二者之间，但明显高于中华按蚊区。结论现阶段主要疟区为嗜人按蚊和微小按蚊地区，是仍须重点防治的疟区，监测措施不可过于简化，中华按蚊地区疫情稳步下降，可适当简化防治措施，但应加强对流动人口的疟疾管理。
Objective To determine epidemioligical feature of malaria transmission in different vectors areas. Methods It was divided to the areas of An. Sinensis, An. Anthropophagus and An. Minimus distribution, according to different vectors,and analysis malaria epidemiology for the three areas. Results The incidence was highest of 0.427‰,the average accounted for 83.81% of the total cases,the blood examined positive rate was 0.49%, the majorfity focal points were local indigenous, in the area of An. Anthropophagus.The dates of above aspects were 0. 046‰,11 .93% and 0.04% respectively,but the most of focies were imported in An. Sinensis distribution areas. Conchusion Presently, the areas of An. Anthropophagus and An. Minimus were main malarial epidemic regions, which should be emphasis antimalaria. The morbidity was being decreased in An. Sinensis areas, can besimplify sur- veillance measures as well as strengthening malarial management for the mobile population.
