摘　　要：目的了解四川省华支睾吸虫病流行现状,为指导四川省华支睾吸虫病防治提供科学依据。方法2016—2020年,按照全国及四川省肝吸虫病及土源性线虫病监测方案,每年在未开展规范化监测的县(市、区)选定流动监测点,乐山市五通桥区为固定监测点,采用改良加藤厚涂片法(一粪两检)检查人群华支睾吸虫虫卵。2017—2020年在固定监测点用压片法检测淡水鱼虾囊蚴,用改良加藤厚涂片法检测猫、犬等保虫宿主粪便,对粪检人群开展人群卫生知识与行为问卷调查。结果2016—2020年,流动监测点共调查143311人,查出华支睾吸虫感染者28人,感染率为0.02%。2016—2020年人群华支睾吸虫感染率均为较低水平,分别为0.01%(5/34967)、0.02%(6/33507)、0.04%(7/19326)、0.02%(7/30256)、0.01%(3/25255),不同年份感染率差异无统计学意义(χ^(2)=4.249,P=0.373)。川西平原和丘陵地区华支睾吸虫感染率最高,分别为0.03%(6/20217)和0.03%(19/64989);川西北高原未查出华支睾吸虫感染,不同地形间感染率差异有统计学意义(χ^(2)=9.949,P=0.028)。共有18个县(市、区)查出了华支睾吸虫感染,占流动监测点总数的14.06%。男性华支睾吸虫感染率为0.02%(13/68316),女性为0.02%(15/74995),差异无统计学意义(χ^(2)=0.017,P=0.895);40~59岁组和≥60岁组感染率分别为0.02%(12/48446)和0.02%(12/48873),0~9岁组未检出,不同年龄组人群感染率差异无统计学意义(χ^(2)=4.721,P=0.291);初中组和高中、中专或中技组人群华支睾吸虫感染率分别为0.03%(12/35401)和0.03%(2/7772),大专及以上组未检出,不同文化程度人群华支睾吸虫感染率差异无统计学意义(χ^(2)=5.155,P=0.326);农民组和其他职业组华支睾吸虫感染率分别为0.02%(24/107679)和0.02%(2/9525),幼托儿童、散居儿童、医务人员组未检出,不同职业人群华支睾吸虫感染率差异无统计学意义(χ^(2)=1.794,P=0.805)。2016—2020年,固定监测点的人群�Objective To understand the prevalence of clonorchiasis in Sichuan Province for scientific guidance to prevention and control of Clonorchis sinensis infection in Sichuan area.Methods By the national and Sichuan provincial monitoring plans for clonorchiasis and soil-transmitted nematodes,we selected certain mobile monitoring sites annually from the counties(cities/districts)without standardized surveillance,and Wutongqiao District of Leshan City as regular monitoring sites.Modified Kato-Katz thick smear technique(two slides/one sample)was used to detect the eggs of Clonorchis sinensis in population.In 2017—2020,the metacercariae in fresh water fish and shrimp were detected by compression method,and the feces of the reservoir host,including cat,dog or pig was detected by modified Kato-Katz thick smear method.A questionnaire survey on health knowledge and behavior was carried out among the population undergone fecal examination.Results From 2016 to 2020,a total of 143311 people in the mobile surveillance sites underwent investigation,which revealed infection with Clonorchis sinensis in 28,with an infection rate of 0.02%.The infection rate in population remained relative lower,ranging in 0.01%(5/34967),0.02%(6/33507),0.04%(7/19326),0.02%(7/30256)and 0.01%(3/25255)between 2016 and 2020,respectively.There was no significant difference in infection rate in different years(χ^(2)=4.249,P=0.373).The highest infection rate of Clonorchis sinensis was seen in the plain(0.03%,6/20217)and hilly area(0.03%,19/64989)of Western Sichuan,yet clonorchiasis was not detected in the Northwest Sichuan Plateau.The difference was insignificant converging diverse terrain(χ^(2)=9.949,P=0.028).Clonorchis sinensis was detected in 18 counties,accounting for 14.06%of the total number of mobile surveillance sites.The infection rate of clonorchiasis was 0.02%(13/68316)in males and 0.02%(15/74995)in females,without significant difference between genders(χ^(2)=0.017,P=0.895).The infection was 0.02%(12/48446)and 0.02%(12/48873),respectively for
