１９８７～１９８９年，采取分层整群随机抽样的方法，对我区２０个县、市１００个点，进行了人体肠道寄生虫分确调查，共粪检５１８８３人，发现线虫７种，其中蛔虫、鞭虫、钩虫（美洲钩虫和二十指肠钩虫）、蛲虫、粪类园线虫、东方毛园线虫的感染率分别为６５．９８％、４７．７１％、３７．８５％、３５．５０％、１．０９％和０．０２％。肠道线虫总感染率为８２．７４％。蛔虫感染者以中轻度为主，鞭虫、钧虫则以轻度感染为主。钩虫感染者中，单纯感染美洲钩虫者占５８．１２％，单纯感染十二指肠钩虫者占２８．３０％，混合感染者占１３．５７％。蛲虫感染者以儿童为高。调查结果表明，我区肠道线虫感染极为普遍，已成为当前影响儿童身心健康和威胁农业劳动力不可忽视的病种，应引起各级政府和有关部门的重视。
From 1987 to 1989, stratified cluster random sampling method was used to survey the human intestinal parasites in 20 counties and 100 cities in our district, with a total of 51,883 feces and 7 species of nematodes found The infection rates of roundworm, whipworm, hookworm (hookworm and nodular hookworm), pinworm, dung park nematode and oriental garden worm were 65.98%, 47.71%, 37.85%, 35 .50%, 1.09% and 0.02%. The total infection rate of intestinal nematode was 82.74%. Roundworm infection were mild, whipworm, Jun insects are mainly mild infection. Among hookworm infected persons, 58.12% were infected with hookworm alone, 28.30% were infected with hookworm alone, and 13.57% were mixed with infected hookworm. Pinworm infection is high in children. The survey results showed that the gut nematode infection in our area is extremely common and has become a disease that can not be neglected by the current physical and psychological health and threatening the agricultural labor force in our region and should be given the attention of all levels of government and relevant departments.
