罗阿丝虫病呈明显的地理分布,以中非热带雨林为主。主要媒介是斑虻。人是罗阿丝虫唯一的贮存宿主。作者自1991年起用伊维菌素治疗罗阿丝虫病,以评价用伊维菌素控制罗阿丝虫病流行的可能性。 选择喀麦隆南部一个罗阿丝虫病高度流行(微丝蚴血症率为30％)的热带雨林村落为研究地区。将该村700个住户中的450户常住居民编入两年调查计划,共计868人。平均28.6岁(0—87岁),男女比例是0.94:1。
Loach filariasis showed obvious geographical distribution, mainly in the Central African tropical rain forest. The main medium is spotted. People are the only storage host of Lohs. The authors treated lorazacosis with ivermectin since 1991 to evaluate the possibility of controlling loach’s infection with ivermectin. A southern part of Cameroon was selected as the study area for a tropical rain forest village with a high prevalence of Loach’s filariasis (microfilariae rate of 30%). 450 permanent residents of the 700 households in the village were included in the two-year investigation plan, for a total of 868 people. Average 28.6 years (0-87 years), male to female ratio is 0.94: 1.
