摘　　要：目的了解广州市(辖区内花都、增城)阻断传播血吸虫病后的疫情监测动态。方法建立阻断血吸虫病后的监测系统,包括对钉螺、传染源、低年龄组人群及外来人员同时进行监测。结果1991～2000年共查螺3052亩,只查到杂螺,均未发现活钉螺。皮试低年龄组人群和外来人员4412人,阳性154人,平均阳性率为3.49%,阳性者均采用粪检尼龙袋集卵孵化法复查均未发现血吸虫卵阳性病人。解剖野鼠1278只作直肠压片检查,均未发现血吸虫卵阳性鼠。结论广州市血吸虫病阻断传播后防治成果是巩固的,但随着近几年湖区几省血吸虫病呈上升趋势,且局部出现暴发流行,因此必须加强监测力度严防外来传染原及钉螺的传入。Objective To explore the epidemic situation of schistosomiasis after interdicted the transmission of the disease in Huadu and Zengeheng section of Guangzhou.
