采用多种检查方法以进一步调查少数民族居民寄生虫感染的种类、感染率、感染度。结果：查出寄生虫１２种，感染一种虫的占８６．８％，二种虫的占１３．２％，居民平均感染率为３０．９％，其中蛔虫为１０．８％，蛲虫为３９．３％，其余低于１０％；华枝睾吸虫的感染度属中度，线虫、原虫、绦虫均属轻度。男性感染率为２８．１％，女性为２４．６％；中间宿主——纹沼螺全部阴性，鱼感染率为０．４％。提示：不同年龄组人群体内虫种构成比不同，感染率和感染度也不同，这可能与居民生产生活接触土壤和粪便的频率，生产活动范围等因素有关。居民感染率下降与经济状况改善、卫生意识提高和村民感染机会减少有关 A variety of inspection methods were used to further investigate the types, rates of infection and degree of infection of parasites of ethnic minorities. Results: 12 parasites were detected, 86.8% were infected with one kind of insects, 13.2% were two kinds of insects, and the average infection rate was 30.9%, of which roundworm was 10.8% 39.3% and the remaining less than 10%. The infection degree of Clonorchis sinensis was moderate, and nematodes, protozoa and tapeworms were all mild. The infection rate of males was 28.1% and that of females was 24.6%. The intermediate host, M. matsurasi, was all negative and the fish infection rate was 0.4%. It is suggested that the composition ratio of insects in different age groups is different, and the infection rate and infection degree are also different, which may be related to the frequency of production and living contact with soil and faeces, the scope of production activities and other factors. Inhabitant rates of decline have been associated with improved economic conditions, improved health awareness and fewer opportunities for villager infection
