摘要: 目的 了解传疟媒介在湖北省的分布规律及范围以及与疟疾发病的关系。方法调查各县(市)疟疾发病情况及当地传播媒介种类和分布规律。结果湖北省疟疾流行的媒介有单纯中华按蚊疟区以及兼有嗜人按蚊疟区,通过人血指数调查,嗜人按蚊的媒介能量平均高出中华按蚊的44.47倍。嗜人按蚊区疟疾发病数占全省发病数的81.38%~93.84%。结论湖北省疟疾近10年流行主要是在有嗜人按蚊的地区。其特点是发病率高、波动大,有些已形成顽固的疫点,目前防制重点应放在有嗜人按蚊的地区。

Abstract: Objective To find out the relationship between malaria morbidity and distribution of their vectors. Methods Cross section study was employed for malaria cases investigation,vectors survey and its distribution. The vectorial capacity was evaluated via human blood index survey. Results The malaria endemics could be divided into one-vector-endemics in which only Anopheles sinensis is recorded,and two-vector-endemics in which A.sinensisandA.anthropophagusare recorded. The vectorial capacity in two-vector-endemics is as 44.47 times as that in one vector endemics. The malaria cases of two vector endemics ranges from 81.38% to 93.84% of the total cases of Hubei Province. Conclusion The malaria epidemic is related with the distribution ofA.anthropophagus. It suggested that the malaria control should focus onA.anthropophagus.
