目的 评估金湖县达到血吸虫病消除标准情况,总结经验,查找问题,为指导消除后的血吸虫病防治工作提供科学依据.方法 对金湖县达到传播阻断标准以来的疫情资料、自评资料和工作资料进行审核.随机抽取3个镇各1个村进行现场评估.采用血清学方法(DDIA),每村人群查病不少于1 000人,阳性者采用尼龙绢袋集卵孵化法(1粪3检)检查.采用粪便毛蚴孵化法(1粪3检)每村查畜100头.采用系统抽样结合环境抽查法对抽样村全部历史有螺环境和可疑环境进行钉螺调查,每村查螺框数不少于2 000框.对金湖县血吸虫病防治监测队伍、疫情报告、实验室检测能力以及疫情处置能力等进行评估.结果 金湖县达到血吸虫病传播阻断后的1998-2016年,累计DDIA检查73 555人次,阳性814人次,阳性率1.11％;粪检11 394人次,发现血吸虫病人1例,阳性率0.01％.家畜查病2 150头,未发现病畜.累计查螺36 287.60 hm2,发现钉螺面积70.87 hm2,其中新发现钉螺面积28.18 hm2.解剖钉螺8 560只,未发现阳性.现场评估DDIA检测3 016人,阳性率2.82％.病原学检查85人,未发现血吸虫病人.家畜查病290头,未发现病畜.查螺面积34.71 hm2,未发现钉螺.专业人员螺类鉴别、钉螺解剖、血清学实验和病原学实验等4项技能测试合格率均为100％,临床医生理论知识考试正确率为97.78％.资料评估得分为92.5分.结论 金湖县自血吸虫病传播阻断后未发现本地感染的血吸虫病人、病畜和感染性钉螺,达到了我国消除血吸虫病标准,今后应完善监测工作体系,加强螺情、病情监测,巩固防治成果.“,”Objective To evaluate the status of schistosomiasis elimination in Jinhu County and summarize the experience,so as to provide the evidence for guiding the prevention and control of schistosomiasis after the elimination.Methods The epidemic data,self-assessment data and work data were reviewed since the county achieved the standard of schistosomiasis transmission interruption.Three villages were randomly selected from 3 towns (one of each town) for field assessment.The serological method (DDIA) was used to detect schistosomiasis in no less than 1 000 people in each village.The positive persons were further surveyed by using the nylon spun bag egg hatching method (1 feces sample,3 examinations).The livestock (100 head in each village) were investigated for schistosome infection by using the miracidium hatching method (1 feces sample,3 examinations).Oncomelania hupensis snails were investigated by the systematic sampling and environmental sampling methods in all the historic environments with snail habitats and suspicious environments.The schistosomiasis control monitoring team,epidemic reports,laboratory testing ability and disposal capacity of epidemic situation of personnel were evaluated in Jinhu County.Results After the county achieved the standard of schistosomiasis transmission interruption,from 1998 to 2016,73 555 person-times were surveyed with DDIA for schistosomiasis.Of those,there were 814 positives,with a rate of 1.11％.A total of 11 394 person-times received the stool examinations and only one person was found with schistosome infection (0.01％).Totally 2 150 head of livestock were detected for schistosome infection but no one was positive.The total area surveyed for O.hupensis snail habitats was 36 287.60 hm2,and the area with snail habitats was 70.87 hm2.The new area with snail habitats was 28.18 hm2.A total of 8 560 snails were dissected for schistosome infection but no positive was found.In the field,3 016 persons were surveyed for schistosome infection with DDIA,and the positive rate was 2.82％.Totally 85 people were detected with the stool examination but no schistosomiasis case was found.Totally 290 head of livestock were detected for schistosome infection,but no positive was found.The area surveyed for snails was 34.71 hm2,but no O.hupensis snail was found.The qualified rates of 4 skills,such as snail identification,O.hupensis snail anatomy,serological experiment,and pathogenic experiment,were all 100％.The accuracy rate of the theoretical knowledge examination of clinicians was 97.78％,and the score of the datum assessment was 92.5 points.Conclusions No local schistosome-infected persons,livestock,and O.hupensis snails are found since Jinhu County achieved the standard of schistosomiasis transmission interruption,which means the county has achieved the standard of schistosomiasis elimination in China.In the future,the monitoring system should be perfected,and the monitoring of snail condition and schistosomiasis state should be strengthened in order to consolidate the achievements of schistosomiasis prevention and control.
