目的 对阜阳市监测点 1 991 2 0 0 0年的监测结果进行总结 ,为有针对性地制订防制对策提供依据。方法 根据《全国流行性出血热监测方案》的要求 ,对人间疫情及鼠间感染情况进行监测。结果 1 0年间共发病 1 51 96例 ,年平均发病率 1 0 .2 5/1 0万 ,呈逐年下降趋势 ;平均病死率 2 .34 % ;发病季节曲线低谷 (57月 )有抬高趋势 (P <0 .0 1 ) ;野外优势鼠种为黑线姬鼠 (77.1 7% ) ,鼠密度为 1 2 .67% ,带毒率为 7.46 % ;室内优势鼠种为褐家鼠 (53 .1 3 % ) ,鼠密度为 8.63 % ,带毒率为 9.56 %。结论 流行强度、疫情的地区季节分布发生的变化表明应继续加强监测工作 ,密切注意流行动态及鼠密度和带毒率的变化 ,以指导防制规划的制订
Objective To summarize the monitoring results of monitoring stations in Fuyang City from 1991 to 2000, and provide the evidence for targeted prevention and control measures. Methods According to the requirements of “National Epidemic Haemorrhagic Fever Surveillance Program”, the epidemic situation of human and the infection in rats were monitored. Results A total of 1 51 96 cases were reported in the past 10 years, with an average annual incidence of 10.25 / 100,000, showing a declining trend year by year. The average mortality rate was 2.34%. There was an upward trend in the trough of the onset season (57 months) (P <0.01). The dominant species in the field were Apodemus agrarius (77.1%), the rat density was 12.67%, and the infection rate was 7.46%. The dominant species were Rattus norvegicus .1 3%), the rat density was 8.63%, and the rate of poisoning was 9.56%. Conclusions The changes of epidemic intensity and epidemic season regional distribution indicate that monitoring work should continue to be strengthened and pay close attention to the change of epidemic dynamics and rat density and virulence rate so as to guide the formulation of prevention and control plan
