目的开展血吸虫病监测,以掌握该年度武汉市血吸虫病流行状况及影响因素,为制定进一步的防治对策提供依据。方法以行政村为单位,采用分层整群随机抽样方法确定监测点。对远城区监测点进行人群病情监测、耕牛病情监测及螺情监测;对中心城区监测点进行沿江居民(或沿江中小学校学生)以及流动人口病情监测。结果全市30个监测点,共调查居民19012人,耕牛1622头,调查有螺及可疑环境34处1330.73万m2。居民粪检阳性率为0.32%,较2007年0.76%下降了57.89%。耕牛粪阳率为0.86%,较2007年1.33%下降了35.34%。垸内有螺面积4.20万m2,活螺平均密度0.0310~0.3529只/0.11m2,钉螺感染率为0;垸外有螺面积742.13万m2,活螺平均密度0.0065~1.1400只/0.11m2,钉螺感染率为0.59%。结论采取的综合防治措施取得了较明显的防治成效。
Objective To carry out the monitoring of schistosomiasis so as to grasp the prevalence and influencing factors of schistosomiasis in Wuhan during the year and provide the basis for further prevention and control measures. Methods Taking the administrative village as a unit, stratified cluster random sampling method was used to determine the monitoring points. To monitor the condition of farms in urban areas, monitor the condition of beef cattle and detect the snail; monitor the residents in the downtown area (or primary and secondary school students along the river) and the floating population for the monitoring points in the downtown area. Results The city’s 30 monitoring points, a total of 19012 residents were surveyed, 1622 cattle, survey snail and suspicious environment 34 13307300 m2. The positive rate of fecal examination was 0.32%, down 57.89% from 0.76% in 2007. The positive rate of cattle dung was 0.86%, down 35.34% from 1.33% in 2007. The embankment has a snail area of 42,200 m2, the average density of live snails is 0.0310 ~ 0.3529 /0.11 m2, and the infection rate of snails is 0; the snail has an area of 7,421,300 m2 and the average density of live snails ranges from 0.0065 to 1.1400 /0.11 m2; The rate is 0.59%. Conclusion The comprehensive prevention and control measures adopted have achieved obvious prevention and cure effects.
