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 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。
Objective To evaluate and classify cystic echinococcosis in the counties (cities, districts and flags) in endemic areas of non-Tibetan Plateau in our country to understand the epidemiological characteristics and rules of cystic echinococcosis in this area. Sexual prevention and control measures to provide the basis. Methods Based on the survey data of 174 cases of cystic echinococcosis in counties (cities, districts and banners) of the 2012 national echinococcosis epidemic survey database, the prevalence rate, the infection rate of domestic animals, Antigen positive rate and other indicators, using sample clustering analysis. Results 174 cystic echinococcosis non-Tibetan Plateau counties (cities, districts, and flags) can be divided into four main types of spatial distribution. Among them, the first category includes 3 counties with high prevalence among the population, low infection rate of livestock and low positive rate of Echinococcus globosus. The second category includes 20 counties (cities and districts) with low prevalence , The rate of livestock infection was high, and the positive rate of Echinococcus globosensis fecal antigen was low. The third category consisted of 39 counties (cities, districts and flags) with low population prevalence, low infection rate of domestic animals, The rate in the fourth category includes 112 counties, and the above three indexes are all lower. Conclusions The clustering results are consistent with the prevalence of cystic echinococcosis in the non-Tibetan Plateau areas. The epidemiological characteristics and geographical distribution of the four types of cysticercus can provide the basis for the classification management and guidance of hydatid disease control in this area.
