宜昌市夷陵区血吸虫病传播阻断后24年监测

Surveillance of schistosomiasis in Yiling District of Yichang City where schistosomiasis transmission has been interrupted for 24 years

对宜昌市夷陵区1988年以来血吸虫病监测工作资料进行分析。24年间,夷陵区累计查出有螺村2个,有螺环境24处(次),有螺面积达5.52 hm2,未发现感染性钉螺;人群查病血检共71 353人,发现阳性者814人,阳性率1.1%;病原学检查817人,未发现阳性;耕牛血检共9 353头,阳性24头,阳性率为0.25%,粪检未发现阳性耕牛。提示,夷陵区实现血吸虫病传播阻断后成果巩固,内源性感染已完全消除,但仍存在疫情反弹的潜在威胁,故仍需加大经费投入力度,加强流动人员监测,进一步巩固防治成果。
