【摘要】 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。更多还原

【Abstract】 Fecal specimens collected from 9 156 people in 18 sites of 9 counties in the eastern agricultural areas of Qinghai Province were examined according to the defined regulations of the “Nationwide Survey of Human Parasite Distribution”. The total infection rate was 54.0%. Polyparasitism was revealed in 23.4% of the infected people. The 15 species of parasites detected in the survey included 6 species of helminths with the highest infection rate of 43.5% for Ascaris lumbricoides , and 9 species of protozoa with the highest infection rate of 8.3% for Entamoeba coli . The features of human intestinal parasite infections and distribution were summarized as follows: Residents under 15 years old showed high incidence; the infection rate was significantly higher in females than in males; the minorities were more severely affected; parasite species and incidence were obviously different with topography,hydrography and altitude. Generally, the infection rate had a tendency to escalate from northwest to southeast of the investigated area.更多还原
