新疆和布克赛尔蒙古自治县人群和羊群肝包虫病现场筛查报告

摘要

目的 B了解新疆和布克赛尔县人群和羊群肝包虫病感染情况,以评价包虫病防控措施.方法 在和布克赛尔县采用现患筛查的抽查方法,以肝包虫病超声声像图特征作为诊断标准,现场筛查人群和羊群肝包虫病,并比较分析不同筛查点患病情况.结果 超声声像图显示,人群肝包虫病检出率为4.4％(23/521),囊性包虫病检出率为4.0％(21/521),泡性包虫病检出率为0.8％(4/521),羊群感染率为3.8％(7/180).5个筛查点中查干库勒乡人群和羊群感染率最高,人群检出率与其他各筛查点相比差异无统计学意义,羊群检出率与巴音傲瓦乡相比差异有统计学意义(x2=4.8259,P=0.0280),作为包虫病中间宿主绵羊的感染率高于人群.结论 和布克赛尔县人群和羊群肝包虫病仍呈高流行趋势.%Objective To investigate the prevalence of human and ovine hepatic hydatid disease in Hobukesar Mongolian Autonomous County of Xinjiang (HMACX) and to evaluate the related strategies for prevention and control of the disease.Methods A prevalence screening method was used to screen local residents and sheep for hydatid disease in HMACX.Based on B ultrasound images,the screening programs on people and sheep in different sites were carried and the findings were comparatively analyzed.Results Findings of B ultrasound images through screening program among human beings showed that the positive rates of hydatid diseaseas 4.4％ (23/521),of cystic echinococcosis and alveolar echinococcosis as 4.0％ (21/521) and 0.8％ (4/521) respectively.The infection rate on sheep was 3.8％ (7/180).The positive rates of human and ovine hepatic hydatid disease in Township Chagangule were higher than in other areas.There was no significant statistical difference noticed on human positive rates between Township Chagangule and other areas.Statistically,significant difference for positive rate in ovine was seen between Township Chagangule and Township Bayinaowa (x2=4.8259,P=0.0280).As intermediate host of hydatid disease,the infection rate in sheep was higher than that in human beings at Township Chagangule.Conclusion HMACX remained a highly endemic area for human and ovine hydatid disease.
