本文按全国人体寄生虫分布调查实施细则的要求和方法，对青海省东部农业区９县１８个调查点的９１５６人进行了一次性粪检。其寄生虫总感染率为５４．０％，其中感染１种寄生虫者占总感染人数的７６．６％，同时感染２、３、４、５和６种寄生虫者分别占１９．４％、３．４％、０．４％、０．０６％和０．０４％。本次共查见寄生虫１５种，其中蠕虫６种，以蛔虫的感染率为最高（４３．５％），原虫９种，以结肠内阿米巴感染率为最高（８．３％）。调查结果表明，本区人体寄生虫感染分布的特点是：以小于１５岁的少年儿童感染率高；女性感染率显著高于男性；少数民族感染率较高；地区分布有明显差异，有随地形、水系和海拔之不同表现为虫种和感染率不同。总的来看，寄生虫的感染水平从西北向东南有上升的趋势。
According to the requirements and methods of the National Implementation Survey of the Distribution of Human Parasites, 9156 people from 18 survey sites in 9 counties in the eastern agricultural region of Qinghai Province were examined once. The total infection rate of parasites was 54.0%, of which 76.6% were infected with one type of parasite, and 19.4% were infected with 2, 3, 4, 5, and 6 parasites at the same time. , 3.4%, 0.4%, 0.06% and 0.04%. A total of 15 parasites were investigated in this investigation, of which 6 species were helminths, with the highest rate of aphid infection (43.5%) and 9 species of protozoa, with the highest rate of colonic amoeba infection (8.3%). The survey results showed that the distribution of human parasites in the district is characterized by high infection rates among young children younger than 15 years; the infection rate of females is significantly higher than that of males; the infection rate of ethnic minorities is high; the regional distribution is significantly different, with the topography The differences in water systems, elevations, and elevations are manifested by differences in insect species and infection rates. In general, the level of parasite infection has risen from northwest to southeast.
