目的通过现况流行病学方法和实验室检测,调查甘肃省武都县7个村庄人群肠道寄生蠕虫的感染状况。方法根据生活水平、地理环境和交通条件等选择武都县的7个自然村,使用改良加藤氏厚涂片法,在光学显微镜下检查肠道蠕虫虫卵。结果在7个村庄总共调查了673人,其中12岁以下儿童占总调查人数的肠道蠕虫感染率为44．7％,蛔虫感染率为41．2％,鞭虫感染率为10．0％,蛲虫感染率为3．6％, 蛔虫和鞭虫混合感染率为6．8％。结论人体肠道寄生性蠕虫在武都县一些农村地区的感染率还比较高, 肠道蠕虫感染程度与当地农民的经济收入、生活水平、生产方式、生活习惯和卫生条件等有密切的关系。
Objective To investigate the status of intestinal parasitic worms in seven villages in Wudu County, Gansu Province through epidemiological methods and laboratory tests. Methods Seven natural villages in Wudu County were selected according to their living standards, geographical environment and traffic conditions, and the gut worm eggs were examined under a light microscope with a modified Katsushi thick smear method. Results A total of 673 people were surveyed in 7 villages. Among them, the rate of intestinal worms among children under 12 years of age was 44.7%, that of roundworm was 41.2% and that of whipworm was 10.0% , The pinworm infection rate was 3.6%, roundworm and whipworm mixed infection rate was 6.8%. Conclusions The human intestinal parasitic worm has relatively high infection rate in some rural areas in Wudu County. The infection rate of intestinal worm is closely related to the economic income, living standard, production method, living habits and hygiene conditions of local peasants.
