黑龙江人体寄生虫分布调查结果的分析

根据卫生部１９８６年《关于全国人体寄生虫分布调查的通知》要求，于１９８８－１９９１年，按全国人体寄生虫分布调查实施细则方法，对黑龙江省６个片区２６个县（市）１０１个调查点５２１３１人进行了人体寄生虫分布调查。共查见人体寄生虫１７种，其中原虫１０种，蠕虫７种。寄生虫总感染率为１７．５％。各种寄生虫的感染率分别为溶组织内阿米巴０．２％、结肠内阿米巴１％、哈氏内阿米巴０．０２％、微小内蜒阿米巴０．４％、布氏嗜碘阿米巴０．０７％、贾第虫０．３％、结肠小袋纤毛虫０．０１％、人芽囊原虫０．２％、人毛滴虫１例、等孢球虫２例、蛔虫１０．３％、鞭虫０．６％、粪类圆线虫０．０２％、华支睾吸虫１．２％、猪带绦虫０．１％、微小膜壳绦虫０．０３％和１５岁以下儿童蛲虫感染率的１６％。男、女感染率分别为１７．６％与１７．４％，两者间差别无显著意义（χ２＝１．０８９１，Ｐ＞０．０５）。蛔虫、蛲虫以学龄前儿童和中、小学生感染率最高，分别为２４．９％和２２．３％。华支睾吸虫以渔民的感染率为最高，为２．９％。经济收入的高低与人体寄生虫感染有关。通过本次调查，为我省制定防治规划、开展寄生虫病防治工作提供了重要的科学依据。

AN EVALUATION ON SURVEY OF HUMAN PARASITE DISTRIBUTION IN HELONGJIANG PROVINGE

As part of the Nationwide Survey of Human Parasite Distribution, a rando mized study based on cluster sampling was pursued in 101 pilot sites of 26 counties/cities in Heilongjiang with a coverage of 52 131 people in 1988-1991. Altogether 17 species of parasites involving 10 species of protozoa and 7 species of helminths were exhibited, the cumulative infection rate being 17.5%. The discovered species and the infection rates were noted as: Entamoeba histolytica 0.2%, Entamoeba coli 1.0%, Entamoeba hartmanni 0.02%, Endolimax nana 0.4% , Iodamoeba buetschlii 0.07%,Giardia lamblia 0.3%, Balantidium coli 0.01%, Blastocystis hominis 0.2%, Trichomonas hominis one cases, Coccidia sp. 2 cases, Ascaris lumbricoides 10.3%, Trichuris trichiura 0.6%, Strongyloides stercoralis 0.02%, Clonorchis sinensis 1.2%, Taenia solium 0.1%,Hymenolepis nana 0.03%, Enterobius vermicularis (<15 years of age)16.0%. Sex based difference did not occur. High infection rates of A. lumbricoides and E. vermicularis fell on preschool children as well as pupils and middle school students, showing 24.9% for the former species, and 22.3% for the latter. C. sinensis showed its top infection rate of 2.9% in fishermen. Prevalence of the disclosed parasites in population was fundamentally related to socioeconomic status.
