摘要

Objective To study current status and influential factors of major human parasitic diseases in the rural areas of Xinyu,Jiangxi Province,and also to predict the trend and identify the high risk population,so as to provide scientific evidence for the development of control strategies and evaluation of the effects of prevention and control.Methods Modified thick smear Kato-Katz method,test tube filter paper culture,adhesive cellophane anal swab,saline smear and iodine staining method were used for feces ex-amination to detect nematodes,tapeworms,protozoa and liver flukes.Results In the 764 examinees from the 3 rural survey points,the number of people with positive infection was 53,with an infection rate of 6.94%,of which the infection rate of Ascaris lumbricoides was 0.13% and those of hookworm,Trichuris trichiura,Enterobius vermicularis and liver fluke were 5.24%,0.26%,1.05% and 0.26% respectively.Neither tenia nor protozoa were detected.Conclusion The infection rate of human parasites among rural inhabit-ants of Yushui area,Xinyu city,as obtained from the survey was obviously decreased,as compared with the average infection rate a-mong the inhabitants of Jiangxi Province in 2004,with hookworm infection as the main infection and elderly farmers with an age of 50 and older as chief victims.%目的：了解和掌握新余市农村重点寄生虫感染现状及影响因素，预测流行趋势，明确高危人群，为制定本市重点寄生虫病防治策略和评价防治效果提供科学依据。方法本次调查采用改良加藤厚涂片法、试管滤纸培养法、透明胶纸肛拭法、生理盐水涂片法和碘液涂片法对受检者进行粪检，查找线虫、绦虫、原虫以及肝吸虫。结果3个农村调查点，共计764名受检者（制片1538张），其中感染阳性人数为53人，感染率为6．94％，其中蛔虫感染率为0．13％、钩虫感染率为5．24％、鞭虫感染率为0．26％、蛲虫感染率为1．18％、肝吸虫感染率为0．26％，未检出带绦虫和原虫。结论此次调查新余市渝水区农村居民人体寄生虫的感染率同2004年的江西省平均感染率相比，呈下降趋势，以钩虫感染为主，主要集中在50岁以上的中老年务农人员。
