目的掌握2005-2012年南县新尚村血吸虫病监测点的疫情变化趋势,为今后的防治工作提供科学依据。方法根据《全国血吸虫病监测方案(试行)》和《全国血吸虫病监测方案操作手册》的要求,开展人畜病情、螺情和相关因素调查并汇总监测数据,分析监测结果。结果 8年来监测点居民感染率在0.25%~0.72%之间波动,家畜感染率由16.67%下降至0,活螺密度维持在0.02~0.16只/0.1m2较低水平,感染螺密度由0.0014只/0.1m2下降至0。结论监测点疫情呈下降趋势,已达到国家血吸虫病传播控制标准,但居民血检阳性率较高,疫情仍处于不稳定状态,需进一步加强传染控制措施的落实,加大防治力度,防止疫情回升。
Objective To grasp the trend of epidemic situation of schistosomiasis surveillance points in Xinxiang Village, Nanxian County from 2005 to 2012, and provide a scientific basis for future prevention and treatment work. Methods According to the requirements of “National Schistosomiasis Surveillance Program (Trial)” and “Operation Manual of National Schistosomiasis Surveillance Program”, the investigation of human and livestock conditions, snail cases and related factors and the compilation of monitoring data were conducted to analyze the monitoring results. Results The infection rate of residents in monitoring sites fluctuated between 0.25% and 0.72% over the past eight years. The infection rate of domestic animals dropped from 16.67% to 0 and the live spiral density was kept at a relatively low level of 0.02-0.16 /0.1m2. The infection spiral density was 0.0014 /0.1m2 drops to 0. Conclusions The epidemic situation of monitoring points shows a downward trend and has reached the national standard of schistosomiasis control. However, the positive rate of blood tests in residents is high, and the epidemic situation is still in an unstable state. The implementation of infection control measures needs to be further strengthened so as to prevent and control the situation from escalation .
