摘　　要：目的分析2008—2014年扬中市渔民血吸虫病疫情监测结果，为血吸虫病防控提供依据。方法钉螺监测，每年采用系统抽样结合环境抽样的方法对全市沿江渔民集散地采集钉螺，压碎镜检法解剖：病情监测。每年对全市沿江渔民集散地的所有渔民进行血清学和病原学查病。采用胶体染料法进行血清学筛查，采集血清学阳性者粪便进行粪孵检查：防治措施的落实，对查出的有螺环境采用药物喷洒灭螺。对血清学和病原学阳性者采用吡喹酮治疗。发放宣传单、防护油膏，设立警示牌、张贴宣传标语等进行宣传教育。结果2008--2014年调查总框数18244框，查出活螺框6515框．活螺框出现率35．71％（6515／18244），捕获活螺19255只，活螺平均密度分别为1．89、1．33、1．57、0．55、1-42、0．97、0．52只／0．1m^2，检获感染性钉螺19只，仅2008年和2009年发现感染性性钉螺。2008—2014年血清学阳性率分别为5．45％、7．27％、4．10％、4．46％、3．70％、4．20％、2．61％。病原学检查36人，未发现阳性。2008—2014年共杀灭钉螺766．63ha（1ha=10000m^2），累计治疗血清学检查阳性者36人次，发放宣传材料l686份、防护油膏2632支、宣传实物1272份，设立警示牌177块、血防宣讲182次。结论扬中市渔民血吸虫病防治效果很好。但极需加强集散地螺情环境的综合治理．探索适合本地渔民防治的新举措。Objective To analyze the results of surveillance on schistosomiasis in fishermen of Yangzhong City from 2008 to 2014, so as to provide the evidence for prevention and control of schistosomiasis. Methods Monitoring on snail： the method of systematic sampling combined with environmental sampling was adopted to collect snails along the river in the city center where fishermen gathered each year, then the crushed snails were examined under microscopy. Epidemic monitoring： the methods of serology and etiology of the disease were adopted to examine for the disease in all fishermen along the river in the city center each year. The colloidal dye method, dipstick dye immunoassay kit for schistosome antibody （IgG） was used for serologic screening, the serological positive stool samples were then collected for hatch-eggs checking. Preven- tion and control measures of implementation：the snail was controlled with molluscicide-spraying, the positive people of serology and etiology was treated with praziquantel, the flyer （painting） and protective ointment were distributed, warning signs were set up, and propaganda slogan posted, etc. Results Monitoring on snail： A total of 18 244 frames was surveyed from 2008 to 2014 among which 6 515 frames with living snails, the oc- currence rate od frames with living snails was 35.71%（6515/18244）. A total of 19 255 living snails was cap- tured , the annual average densities of living snail were 1.89,1.33,1.57,0.55,1.42, 0.97,0.52 snail/0.1 m^2 re- spectively from 2008 to 2014, the positive snails were found only in 2008 and 2009, 19 positive snails were seized. Epidemic monitoring： from 2008 to 2014, serological positive rates were 5.45%, 7.27%, 4.10%, 7.27%, 3.70%, 4.20%, 2.61% respectively; 36 people were subjected to etiology examination, no positive found. From 2008 to 2014, 766.63 ha（1 ha=10 000 m^2） of oncomelania were killed while the 36 serologically positive peo- ple were treated with praziquantel. 1 686 flyers （painting） and 2 632 protective ointment
