Abstract: Objective Objective To evaluate the effect of soil?transmitted helminthes control through mass deworming and latrine im? provement in rural areas. Methods Methods The data including mass deworming(1998-2000)and latrine improvement(2001-2010) were collected,summarized and analyzed in Danyang City. The infection rate of the soil?transmitted helminthes was monitored annually by using Kato?Katz method from 2001 to 2010. In addition,2 villages with the improved latrines strategy and one vil? lage without the strategy were selected for hygienic evaluation. Results Results Totally 1 130 000 person? times of mass deworming were carried out in Danyang City from 1998 to 2000,and the infection rate of soil transmitted helminthes of human was de? creased from 40.82% to 1.10%. The infection rate(2.49%-4.81%)was bounced in the first five years(from 2001 to 2005)after mass deworming,while it gradually declined in the following five years(from 2006 to 2010)and maintained at a low level (0.07%-0.52%),and there was a significant difference between the average infection rates during the above two stages(χ2 = 353.83,P < 0.01) . There was a negative correlation between the coverage rate of harmless latrine and the infection rate(r = - 0.83,P < 0.01) . Conclusion Conclusion The mass deworming and latrine improvement are effective measures for the control of soil?trans? mitted helminthes infection in rural areas.

摘要: 目的 目的 评价群体驱虫与改厕控制农村地区土源性线虫感染的效果。方法 方法 收集、 整理丹阳市1998-2000年群 体驱虫以及2001-2010年改厕资料, 对两种措施控制土源性线虫感染的效果进行评价。2001-2010年采用改良加藤法 (Kato?Katz) 开展人群土源性线虫感染率监测, 2010年分别选择2个改厕村和1个非改厕村开展卫生学评价。结果 结果 该市 1998-2000年开展群体驱虫113万人次, 人群感染率由40.82%降至1.10%, 驱虫后的前5年 (2001-2005年) 人群感染率有 所反弹 (2.49%~4.81%), 后5年 (2006-2010年) 逐步降低并保持在低水平 (0.07%~0.52%), 前后5年人群平均感染率差 异有统计学意义 (χ2 = 353.83,P<0.01), 人群感染率与无害化户厕覆盖率呈负相关趋势 (r = -0.83,P < 0.01)。结 结 论 论 群体驱虫与改厕可有效控制农村地区人群土源性线虫感染率。
