摘　　要：目的了解安徽省人群华支睾吸虫感染情况,为制定防治措施提供依据。方法2016—2020年在全省56个县(市、区)设立华支睾吸虫病监测点,各监测点按地理方位划分为东、西、南、北、中5个片区,每片区抽取1个乡镇的1个行政村开展调查。在每个行政村整群抽取3周岁以上常住居民作为调查对象,调查人数不少于200人。收集调查对象的粪便标本,采用改良加藤厚涂片法(一粪两检)检测华支睾吸虫感染情况。结果2016—2020年共调查73702人,其中华支睾吸虫感染27人,华支睾吸虫总感染率为0.04%。从监测点来看,有13个县(市、区)发现华支睾吸虫感染者,其中宣城市的宣州区和泾县感染率最高,均为0.30%;其余43个县(市、区)均未发现华支睾吸虫感染者。从生态区来看,华北平原生态区感染率最高,为0.06%;长江中下游平原生态区感染率最低,为0.02%。从年份来看,2016—2020年华支睾吸虫的感染率分别为0.02%、0.04%、0.04%、0.06%和0.02%,总体呈上升趋势,但2020年有波动。从性别来看,男性和女性的感染率分别为0.03%和0.04%。从年龄来看,10~19岁年龄组感染率最高,为0.06%;3~9岁、20~29岁、60~69岁三个年龄组感染率最低,均为0.02%。从文化程度来看,初中组感染率最高,为0.05%;学龄前儿童感染率最低,为0。但感染率在不同监测点、不同生态区、不同年份、不同性别、不同年龄组和不同文化程度之间的差异均无统计学意义(P均>0.05)。结论2016—2020年安徽省人群华支睾吸虫总体感染率较低,但与2015年第三次全国人体重点寄生虫病现状调查时全省的感染率(0.01%)相比有显著提高,提示今后应加强监测和防治。Objective To understand the human prevalence of clonorchiasis in Anhui Province,so as to provide scientific evidences in formulating control strategies for this infection.Methods Monitoring sites for clonorchiasis prevalence were selected in the 56 counties(cities/districts)in Anhui Province between 2016 and 2020,and zoned into 5 areas according to the geographical location(east,west,south,north and middle areas).Then one administrative village was selected from a township to serve as the surveillance site.No less than 200 permanent residents aged 3 years and above were annually included by cluster sampling method from each administrative village.The fecal samples were collected to undergo test of Clonorchis sinensis infection using the modified Kato-Katz thick smear method(two slide reading/one sample).Results From 2016 to 2020,a total of 73702 people underwent the survey,which revealed infection in 27,with a total infection rate being 0.04%.By the surveillance sites,Clonorchis sinensis infection was found in 13 counties(cities/districts),in which Xuanzhou District of Xuancheng City and Jingxian County were listed the highest.The infection rate was 0.30%for the both areas,yet Clonorchis sinensis infection was free in the remaining 43 counties(cities/districts).The highest Clonorchis sinensis infection(0.06%)was observed in the North China Plain in all surveillance sites among the four ecological regions,and the infection was the lowest in plains of the Middle and Lower Reaches of the Yangtze River(0.02%).The total infection rate was 0.02%,0.04%,0.04%,0.06%and 0.02%,respectively from 2016 to 2020,and tended to increase in general,whereas there was a decrease in 2020.By genders,the infection rate was 0.03%in males and 0.04%in females.By age distribution,the infection rate(0.06%)was the highest in population aged between 10 and 19 years old,and the lowest in those aged under 9 years,from 20 to 29,and from 60 to 69 years old(0.02%,respectively,for the three age group).The highest infection with Clonorchis sinensis w
