Abstract: Objective To analyze the results of 3 investigations （2002-2004， 2008-2009， and 2016） of major parasitic diseases in Shixing County， so as to provide the evidence for formulating further control strategies. Methods With the stratified cluster sampling method， 5 administrative villages were investigated. A total of 200 residents aged above 3 years were sampled in each village to investigate the eggs of soil?transmitted nematodes with Kato?Katz technique， and the swab method was applied for detecting the eggs of Enterobius vermicularis in children aged 3?9 years. [χ2] test was used for statistical analysis. Results Totally 3 857 individuals were surveyed for intestinal parasites， and 5 species of parasites were found and the total infection rates were 28.37%， 4.32% and 0.50% in the 3 investigations respectively， and there were statistically significant differences between any two investigations （[χ2]= 287.64， 327.60 and 31.89 respectively， and all P＜0.01）. The infection rates of Ascaris lumbricoides， hookworm， Trichuris trichiura and Clonorchis sinensis significantly decreased in the third investigation compared with those in the first investigation （[χ2] = 424.55， 55.45， 43.40 and 26.12 respectively， all P＜0.01）. However， there was no significant difference between the E. vermicularis infection rates of the first investigation and the third investigation （[χ2]=0.16， P＞0.05）. Conclusions Compared with the status in the first investigation， the infection rates of A. lumbricoides， hookworm， T. trichiura and C. sinensis are significantly decreased by 90% or more in the third investigation. However， the children’s infection rate of E. vermicularis is still very high. Therefore， we should focus on the comprehensive control measures of E. vermicularis infection while formulating further control strategies of parasitic diseases.

摘要： 目的 分析始兴县人体重要寄生虫病流行现状和态势，为制定防治规划提供科学依据。方法 采用分层整群抽样法抽取5个村，每个村抽取3周岁以上居民200人。采用Kato?Katz法粪检土源性线虫虫卵。3 ~ 9周岁儿童加做透明胶纸肛拭法检测蛲虫。采用[χ2]检验进行统计分析。结果 共查出5种寄生虫，三次肠道寄生虫感染调查共查3 857人，总感染率分别为28.37%、4.32%和0.50%，两两比较差异都有统计学意义（[χ2]值分别为287.64、327.60、31.89，P均< 0.01）。第三次调查结果与第一次相比，蛔虫、钩虫、鞭虫、华支睾吸虫感染率都有明显的下降，差异均有统计学意义（[χ2]值分别为424.55、55.45、43.40和26.12，P均< 0.01），蛲虫感染率差异无统计学意义（[χ2]= 0.16，P > 0.05）。结论 与第一次调查年相比，蛔虫、钩虫、鞭虫、华支睾吸虫感染率都大幅下降，但儿童蛲虫感染率仍居高不下，今后制订寄生虫防治措施时应着重考虑蛲虫的综合防治措施。
