摘要:

根据2012年全国细粒棘球蚴病流行情况调查数据库中甘肃省72个县(市、区)细粒棘球蚴病的调查资料,选取人群患病率、家畜感染率和犬棘球绦虫粪抗原阳性率3个指标,采用样本聚类法进行分析。甘肃省人群棘球蚴病患病率为0~1.59%,家畜感染率为0~15.22%,犬粪抗原阳性率为0~16.87%。聚类分析结果显示,72个县(市、区)存在4种流行类型,第一类地区仅包括敦煌市,人群患病率、家畜感染率和犬粪抗原阳性率分别为0.27%、15.22%和16.87%;第二类地区包括4个县(市、区),3个指标分别为0.43%、6.57%和1.83%;第三类地区包括22个县(市、区),3个指标分别为0.22%、1.15%和10.35%;第四类地区包括45个县(市、区),3个指标分别为0.16%、0.58%和1.69%。

Abstract:

The prevalence of hydatid disease in human population and livestock, and the positive rate of echinococcal antigen in canine feces were analyzed with sample clustering method, according to the survey on hydatid disease in 72 counties in Gansu province in the database of the National Survey on Prevalence of Echinococcosis in 2012. The prevalence of hydatid disease in huma and livestock, and the positive rate of echinococcal antigen in canine feces were 0-1.59%, 0-15.22%, and 0-16.87% respectively. Clustering analysis revealed four types of prevalence in the 72 counties. The first type existed only in Dunhuang city, with the three indicators being 0.27%, 15.22% and 16.87%; the second in four counties, with the three indicators being 0.43%, 6.57% and 1.83%; the third in 22 counties, with the three indicators being 0.22%, 1.15% and 10.35%; and the fourth in 45 counties, with the three indicators being 0.16%, 0.58% and 1.69%.
