摘　　要：目的了解广东省顺德市近20年来华支睾吸虫病流行情况及发展趋势，为综合防治该病提供科学依据。方法2014年9月-2015年2月在顺德市对5个镇街居民进行分层随机抽样，用改良加藤厚片涂片法粪检虫卵及进行相关问卷调查，并将调查结果与文献报道自1995年以来的调查结果作对比分析。结果20年来，感染率在38．7％～67．5％之间；感染率男性高于女性，并随着年龄增加而增加；各镇街的感染率有所不同；食用生、未熟淡水鱼及不分开生熟厨具仍是感染的高危因素；知晓华支睾吸虫的感染途径、所致疾病等知识有利于降低发病率；6．73％的居民自知曾感染，9．06％的居民曾接受过驱虫治疗。结论20年来顺德市华支睾吸虫病感染率无明显下降，防控任务十分艰巨，卫生防疫部门仍应积极开展综合性的防控工作，并加强各级医院在查、防、治该病中所起的作用。Objective The objective of the study was to assess the epidemic status and trend of clonorchiasis in Shunde of Guangdong for the past 20 years, and thus to provide a scientific reference for the comprehensive prevention and control of clonorchiasis. Methods Residents from 5 towns in Shunde were selected by stratified random sampling between September of 2014 and February of 2015. The residents were subjected to the Kato-Katz procedure and a questionnaire survey. The results were analyzed and compared with those reported in literatures since 1995. Results During the past 20 years, the infection rate ranged between 38.7% and 67.5%. The infection rate among male was higher than that among female, and has shown to increase with age. The infection rates varied among the towns. Consuming raw or undercooked freshwater fish and mixing kitchenware for raw and cooked food were the high-risk factors for the infection. Being aware of the routes of infection and the associated diseases of Clonorchis sinensis infection was conducive to reducing incidence of disease; 6.73% of the residents were aware of having been infected and 9.06% had received an anthelmintic treatment. Conclusion No significant decrease in infection rate of C. sinensis over the past 20 years is observed, suggesting the level of difficulties of the prevention and control of clonorchiasis in Shunde. The health and epidemic prevention departments should continue to actively implement comprehensive prevention and control measures against clonorchiasis, and strengthen the role of hospitals of all levels in the investigation, prevention, and treatment of the disease.
