摘　　要：目的了解安徽省27个血吸虫病疫情控制县（市、区）疫情现状。方法按照《血吸虫病防治地区达标考核评估方案》确定的抽样调查方法,在安徽省27个血吸虫病疫情控制县（市、区）各抽取3个疫情相对较重的乡（镇）,每个乡（镇）抽取1个疫情相对较重的流行村作为调查现场。调查常住人口和散养家畜病情,以及近3年查出钉螺且人畜活动频繁环境的钉螺感染情况。同时,查阅各县（市、区）近年来感染性钉螺调查结果和当地感染急性血吸虫病疫情资料。结果现场共抽查81个乡（镇）81个村。累计血清学检查34 293人,阳性1 086人,平均阳性率为3.17%（0.65%~9.58%）;累计粪检1 068人,平均阳性率为0.37%（0~4.0%）,推算人群平均感染率为0.01%。累计调查家畜3 057头（只）,其中牛438头,羊2 550只,其他家畜69只,均未查到阳性。累计调查钉螺60 944框,捕获活螺11 261只,解剖全部活螺均未发现感染性钉螺。27个县（市、区）均在调查前2年以上未查出感染性钉螺,平均未查出感染性钉螺年限为2.9年（2~6年）;均已2年以上未发生急性血吸虫病,平均未发生急性血吸虫病年限为4.9年（2~9年）。结论安徽省血吸虫病疫情控制地区人畜病情较低,已查不出感染性钉螺。Objective To understand the epidemic situation of schistosomiasis in 27 counties（cities,districts）that reached the criteria of schistosomiasis infection controlled in Anhui Province. Methods According to the requirement of The National Assessment Scheme of Schistosomiasis,81 administrative villages where the schistosomiasis epidemic situation was relatively heaver in above-mentioned 27 counties（1 village per town,3 towns per county）were sampled and investigated.Results From 2012 to 2014,81 villages were investigated,and 34 293 residents received the serum examinations,and 1086 were positive with a positive rate of 3.17%（0.65%-9.58%）,and the positives received stool examinations and the average stool positive rate was 0.37%（0-4.0%）. The calculated prevalence of human infection was 0.01%. A total of 3 057 domestic animals were investigated including 438 cattle,2 550 sheep,and 69 other animals,and no infections were detected. A total of 11 261 living Oncomelania hupensis snails were collected and detected,but no schistosome infected snails were found. Before this investigation,no infected snails were detected for more than 2 years[average 2.3（2-6）years],and no acute schistosome infection cases were found for more than 2 years[average 4.9（2-9）years]. Conclusion The infection rates of schistosomiasis in residents and domestic animals are relatively low,and no schistosome infected snails are found in the regions.
