广西人体肠道线虫感染情况调查

A Survey of Human Intestinal Parasit In-fection In Guangxi Zhuang Autonomous Re-gion

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。
