摘　　要：目的了解2015年甘肃省棘球蚴病流行现状、评估防治效果,为进一步制定该地区的防治策略和措施提供依据。方法甘肃省56个棘球蚴病流行县中,每县随机抽取2个乡、每乡随机抽取2个村,开展6～12岁儿童血清阳性率和犬粪抗原阳性率调查,于屠宰季节开展流行县家畜感染率调查;用SPSS 20.0软件统计分析调查数据。结果儿童棘球蚴血清阳性率为1.06(103/9 743),以县为单位儿童血清阳性率0.00～7.00%;儿童血清阳性率女性(1.29%,57/4 434)高于男性(0.87%,46/5 309),差异有统计学意义(χ~2=4.057,P<0.05);血清阳性率6岁儿童最低(0.51%),12岁儿童最高(1.52%),不同年龄差异无统计学意义(χ~2=9.509,P>0.05);棘球绦虫犬粪抗原阳性率为2.03%(115/5 654),以县为单位犬粪抗原阳性率0.00～14.00%;牛感染率0.43%(5/1 153),羊感染率0.68%(68/10 023),差异无统计学意义(χ~2=0.955,P>0.05);家畜总感染率为0.65%,以县为单位家畜患病率0.00～5.50%,最高为环县和敦煌市(均为5.50%)。结论甘肃省棘球蚴病流行程度明显减轻,但各县(区)间差异明显,部分县(区)疫情仍然较重;今后应根据不同的流行情况采取因地制宜、分类指导的防治策略。Objective To know epidemic situation of echinococcosis in Gansu province in 2015, evaluate the effect of prevention and control and provide basis for formulating measurement and strategy of prevention and control. Methods There were 2 townships randomly selected in each county among 56 epidemic counties, and 2 villages were randomly selected in each selected towns. Serum positive rate of children aged 6-12 years and positive rate of canine coproantigen were investigated. The infection rate of livestock was investigated during the slaughter period in each epidemic county. Data of the investigation were statistically analyzed through SPSS 20.0. Results The children aged 6-12 years were investigated with serum positive rate of echinococcosis of 1.06%（103/9 743） and the rates by counties were from 0.00 to 7.00%. The serum positive rate of the female（1.29%, 57/4 434） was higher than that of the male（0.87%, 46/5 309） with statistical difference（χ^2=4.057,P〈0.05）. The serum positive rate of children aged 6 years was the lowest（0.51%） and the highest（1.52%） of children aged12 years; there was no statistical difference among ages of children（χ^2=9.509, P〉0.05）. Totally 5 654 canine feces were collected with coproantigen positive rate of 2.03%（115/5 654） and the rates by counties were from 0.00 to 14.00%. In slaughtered livestock, the infection rate was 0.43%（5/1 153） of cattle, and 0.68%（68/10 023） of sheep, with out statistical difference（χ^2=0.955, P〉0.05） between cattle and sheep. The total infection rate of slaughtered livestock was 0.65% and by counties were from 0.00 to 5.50% with the highest in Huan county and Dunhuang city（both 5.50%）. Conclusions The epidemic intensity of echinococcosis greatly declines in Gansu province, but there are great differences in prevalence of echinococcosis among different counties and the epidemic status is still serous in part of them. Different strategies of prevention and control and classification guidance should be taken ac
