农村肠道寄生虫感染动态及影响因素调查分析

目的了解农村人体肠道寄生虫感染现状,观察社会经济因素变化和改水改厕对肠道寄生虫流行的影响。方法选择虞城县曾经开展1990年第一次全国人体寄生虫分布调查的彭庄村和苏楼村作为观察点,彭庄村是改水改厕试点村,调查两村1岁以上常住居民的基本情况及肠道寄生虫感染现状。结果2002 年两村肠道寄生虫总感染率较1990 分别降低了87.15%和61.42%,2002年彭庄村肠道寄生虫感染率显著低于苏楼村。结论　农村居民收入提高、居住环境改善以及改水改厕能够显著降低肠道寄生虫的感染。

Analysis on the Survey of Dynamics and Influent Factors of Intestinal Parasite Infection in Rural Areas

Objective To understand the current state of villagers' intestinal parasite infection and survey the effect of social and economic changes and water-and-toilet-reforms on the epidemic of intestinal parasites. Method Pengzhuang and Sulou, two villages, in Yucheng County were chosen as the surveying sites, where the First National Investigation of Human Parasite Distribution in 1990 was carried out, and Pengzhuang is also one of water-and-toilet-reform testing sites. The villagers' (older than one year ) basic states and their current intestinal parasite infection were investigated. Results The gross ratios of intestinal parasite infection in the two villages in 2002 were reduced by 87.15% and 61.42% individually than that in 1990, and the ratio of intestinal parasite infection in Pengzhuang Village was significantly lower than that in Sulou Village. It is indicated that intestinal parasite infection can be significantly lowered by raising villagers' incomes, by improving their living surroundings and by water-and-toilet-reforming.
