Abstract: Objective　To understand the epidemic status of clonorchiasis sinensis in western region of Jilin Province, so as to provide the evidence for formulating the planning and strategy of prevention and control of the disease. Methods　In 2017, the areas where the residents had the customs of eating Sashimi were selected as the research areas in the western region of Jilin Province, and according to the cluster sampling, 25 villages in 25 towns (each village per town) of 5 counties in the region were selected as the investigation points. The basic information of crowd was collected by a questionnaire investigation. The Kato?Katz method was used for etiological examinations. The results were analyzed statistically. Results　A total of 4 980 people in the 25 villages were investigated, and 1 220 people were infected with Clonorchis sinensis. The average infection rate was 24.50%. There was a significant difference among different counties (cities, districts) in the infection rate of C. sinensis (P < 0.01), and the infection rate in Daan City was the highest (53.82%). In addition, there were significant differences between/among the gender, nation, age, educational level, and occupation in the infection rate (all P values < 0.01). The infection rate of the male was higher than that of the female, the rate of Han was higher than that of other ethnic groups, the rate of the high age group was higher than that of the low age group, the rate of the college degree group was higher than that of the other educational level groups, the rate of the cadre was higher than that of the other occupation groups, and the rate of the group who had vermifuge before the investigation was lower than that of the group who did not have vermifuge. Conclusions　The western region of Jilin Province is still the high?incidence area of clonorchiasis sinensis. Therefore, the comprehensive control and prevention measures, such as giving vermifuge and health education, should be strengthened in key population and areas in the future.

摘要： 目的　掌握吉林省西部地区华支睾吸虫病流行现状，为后续防治策略的制定提供科学依据。方法　2017年按照整群抽样的方法，选择吉林省西部地区有食用生鱼片风俗习惯的县（市、区），每个县（市、区）按东、西、南、北、中5个方位各选取1个乡（镇）、每个乡（镇）各选取1个村作为调查点。采用问卷调查收集居民基本信息。采用Kato?Katz法（1粪2检）检查居民华支睾吸虫感染情况，对检测结果进行描述性分析。结果　在吉林省5个县（市、区）、25个乡（镇）、25个村共调查居民4 980人，检出华支睾吸虫感染者1 220人，人群平均感染率为24.50%。各县（市、区）人群华支睾吸虫感染率差异有统计学意义（χ2 = 793.63，P ＜ 0.01），其中大安市感染率最高（53.82%）。不同性别、民族、年龄、文化程度和职业人群华支睾吸虫感染率差异亦有统计学意义（P均＜ 0.01），其中男性高于女性、汉族高于其他民族、高年龄组高于低年龄组、大专学历高于其他学历、干部职业高于其他职业，检查前服用驱虫药人群感染率低于未服药者。 结论　吉林省西部地区仍为华支睾吸虫病高发区；今后仍应针对重点人群开展服药驱虫和健康教育等综合性防控措施，以有效控制华支睾吸虫病的流行与传播。
