目的通过对清新县流动人口监测结果的分析,探讨优化输入性血吸虫病人的防控措施。方法对清新县流动人口血吸虫病的监测结果进行统计分析。结果2005年清新县对流动人口67045人进行调查,显示有66%的流动人口居住在该县的城乡结合部或农村地区,来自疫区的人群约占流动人口的12%。2001-2008年,采用常规主动监测1052人、选择性主动监测1456人,血吸虫血清抗体阳性率分别为2.57%(27/1052)和4.81%(70/1456),两者差异有统计学意义(χ2=8.25,P<0.01);发现输入性临床诊断慢性病人分别为0例和13例(0.89%),病原确诊病人分别为0例和2例(0.14%)。显示选择性主动监测对查获输入性病例的效果明显优于常规主动监测。结论来自疫区的流动人口中存在一定数量的血吸虫病患者,为做好输入性传染源的防控工作,现阶段要重点开展选择性主动监测,同时加强被动监测,并通过选择灵敏度较高的检查方法以提高监测效果。
Objective To analyze the monitoring results of floating population in Qingxin County to explore the prevention and control measures to optimize the imported schistosomiasis patients. Methods Statistical analysis was made on the monitoring results of schistosomiasis among floating population in Qingxin County. Results In 2005, a total of 67045 migrants were investigated in Qingxin County, showing that 66% of the floating population lived in the urban-rural junction or rural areas of the county, and 12% of the floating population came from affected areas. In the period of 2001-2008, 1052 people were routinely monitored actively and 1456 people were actively monitored. The positive rates of serum antibodies to schistosoma japonicum were 2.57% (27/1052) and 4.81% (70/1456), respectively, with significant difference between the two χ2 = 8.25, P <0.01). There were 0 cases and 13 cases (0.89%) of chronic enteric clinical diagnosis, respectively. There were 0 cases and 2 cases (0.14%) of the pathogen confirmed cases respectively. The results show that selective active surveillance is better than routine active surveillance in detecting imported cases. Conclusion There are a certain number of schistosomiasis patients among the floating population from affected areas. In order to prevent and control input source of infection, selective active monitoring should be emphasized at the present stage, and passive monitoring should be strengthened at the same time. By selecting a higher sensitivity Check the method to improve the monitoring effect.
