Abstract: Objective To understand the endemic characteristics and regularity of cystic echinococcosis by evaluating and classifying its endemic situation in Non Tibetan Plateau regions,so as to provide the evidence for formulating effective preventive and control measures. Methods The prevalence data of cystic echinococcosis in 174 counties(cities,districts,banners)in Non Tibetan Plateau regions from a national survey were collected and analyzed by the sample cluster method in 2012. Results The 174 counties(cities,districts,banners)could be classified into 4 clusters by spatial distribution. The first cluster with human high prevalence rate,low infection rate of livestock,and positive rate of dog stool antigen included 3 counties. The second cluster with high infection rate of livestock,low prevalence rate of human,and positive rate of dog stool antigen included 20 counties(cit? ies) . The third cluster with high positive rate of dog stool antigen,low prevalence rate of human,and low infection rate of livestock included 39 counties(cities,districts,banners) . The fourth cluster with low rates of the above 3 indices included the rest 112 counties. Conclusions The results of the cluster analysis conform to the current epidemiological status of cystic echinococcosis in the Non Tibetan Plateau regions. The epidemiological characteristics and geographical distributions of the four area types will pro? vide a basis for the classified management and guidance of cystic echinococcosis control in these areas.

摘要: 目的 目的 对我国非青藏高原流行区囊型棘球蚴病以县 (市、 区、 旗) 为单位, 进行综合评判并分类, 了解该地区囊型 棘球蚴病的流行特点及规律, 为提出针对性的预防控制措施提供依据。 方法 方法 根据2012年全国包虫病流行情况调查数 据库中174个非青藏高原县 (市、 区、 旗) 囊型棘球蚴病调查资料, 综合人群患病率、 家畜感染率、 犬棘球绦虫粪抗原阳性率 等指标, 采用样本聚类法进行分析。 结果 结果 174个囊型棘球蚴病非青藏高原县 (市、 区、 旗) 可分为4类主要的空间分布区 域。其中第一类区域包括3县, 其人群患病率高, 家畜感染率低, 犬棘球绦虫粪抗原阳性率低; 第二类区域包括20县 (市、 区), 其人群患病率低, 家畜感染率高, 犬棘球绦虫粪抗原阳性率低; 第三类区域包括39县 (市、 区、 旗), 其人群患病率低, 家 畜感染率低, 犬棘球绦虫粪抗原阳性率高, 第四类区域包括112县, 以上3个指标值均较低。 结论 结论 聚类结果与我国囊型 棘球蚴病非青藏高原地区流行区情况相符, 4类地区的流行特点及地理分布可为该区域棘球蚴病防治工作的分类管理与 指导提供依据。
