【摘要】 通过昆虫学和寄生虫学调查,广坝地区疟疾呈不同程度流行,山麓区流行严重,居民带虫率和发病率接近50年代抗疟前水平,丘陵区相对较低,其原因与当地主要传疟媒介大劣按蚊的数量分布有关。工程队宿舍建在距山脚约2km 的丘陵区,受大劣按蚊侵袭机会较少,在采取现行的防治措施下,年发病率预计在3～5%之间,不会出现严重流行。更多还原

【Abstract】 A large hydropower station has been constructing in Guangba area since 1989.In order to predict the malaria epidemic potential during the engineering construction,an epidemiological investigation was conducted using entomological and parasitologica methods. The results show that the difference of malaria prevalence are associated with thel number and distribution of major vector,A,dirus.The prevalence in hilly area is low, while in mountain-foot area is serious where the parasite rate is 39.4% and the incidence from July to August is 20.5% which similar to that of 1950s before antimalaria measures implemented.The constructive workers,camps were set athilly area about two kilometers away from mountaln-foot.Based on present anti-malaria measures,it is predicted that the annual incidnce of malaria is 3—5%,no serious epidemic will take place.更多还原
