目的掌握镇江市全国血吸虫病监测点疫情变化情况。方法按《全国血吸虫病监测方案》的方法,2005~2007年每年对镇江市2个国家级血吸虫病监测点丹徒区三洲村和扬中市石城村开展螺情、病情等纵向观察并进行分析。结果2005年有螺面积、活螺密度、阳性螺密度、血检阳性率分别为38.4 hm2、3.76只/0.1 m2、0.014 8只/0.1 m2、4.60%;2007年分别为41.9 hm2、2.40只/0.1 m2、0.012 8只/0.1 m2、2.07%;活螺密度与血检阳性率在防治措施实施后略有下降。丹徒监测点家畜感染率较高,耕牛感染率为21.1%,羊感染率为5.3%。结论3年血吸虫病疫情监测显示,人群病情相对稳定并维持在较低水平,监测区江滩综合治理和传染源监测等工作仍需进一步加强。
Objective To understand the epidemic situation of schistosomiasis surveillance in Zhenjiang City. Methods According to the method of “national schistosomiasis monitoring program”, longitudinal observation and analysis of two snail diseases monitoring stations in Sanjiang, Dantu District and Shihcheng Village, Yangzhong City were conducted in 2005-2007. Results In 2005, the area of spiral lobe, live lobe density, positive lobe density and blood test positive rate were 38.4 hm2, 3.76 pieces /0.1 m2, 0.0148 pieces /0.1 m2, and 4.6% respectively; in 2007 they were 41.9 hm2,2.40 pieces / 0.1 m2, 0.012 8 /0 m2, and 2.07%. The live lobe density and blood test positive rate decreased slightly after the implementation of control measures. Dantu monitoring point livestock infection rate is higher, the cattle infection rate was 21.1%, sheep infection rate was 5.3%. Conclusion The surveillance of schistosomiasis surveillance in 3 years showed that the population was relatively stable and maintained at a relatively low level. The comprehensive treatment of river banks and the monitoring of infection sources in the monitoring area still need to be further strengthened.
