We screened 3,199 people from Shiqu County, Sichuan Province, China, for abdominal echinococcosis (hydatid disease) by portable ultrasound combined with specific serodiagnostic tests. Both cystic echinococcosis (CE) (Echinococcus granulosus infection) and alveolar echinococcosis (AE) (E. multilocularis) were co-endemic in this area at the highest village prevalence values recorded anywhere in the world: 12.9% were infected with one or the other form (6.8% CE and 6.2% AE). Prevalences of both CE and AE were significantly higher in female than male patients and increased with the age of the person screened. Pastoral herdsmen were at highest risk for infection (prevalence 19.0%). Prevalence of CE varied in 5 townships from 0% to 12.1%, whereas AE prevalence ranged from 0% to 14.3%. Risk factors associated with both infections included the number of owned dogs, frequency of contact with dogs, and sources of drinking water.
我们采用便携式超声检查结合特异性血清学诊断试验，对来自中国四川省石渠县的3199人进行了腹部包虫病（囊型包虫病）筛查。该地区同时流行囊型包虫病（CE，由细粒棘球绦虫感染引起）和泡型包虫病（AE，由多房棘球绦虫引起），是世界上村庄患病率最高的地区之一：12.9%的人感染了其中一种类型（6.8%为囊型包虫病，6.2%为泡型包虫病）。囊型包虫病和泡型包虫病在女性患者中的患病率均显著高于男性，且随着受检者年龄的增长而升高。牧民感染风险最高（患病率为19.0%）。5个乡镇的囊型包虫病患病率在0%至12.1%之间，泡型包虫病患病率在0%至14.3%之间。与这两种感染相关的危险因素包括拥有的犬只数量、与犬只接触的频率以及饮用水源。
