目的调查分析缙云县现阶段3种鼠传疾病在人间与鼠间的自然感染率,为下步防控工作提供参考依据。方法在缙云县3种鼠传疾病的历史疫区及现行高发区的3个乡镇采集健康人群、鼠类样本,对3种鼠传疾病进行血清流行病学横断面调查。结果共采集健康人群血清627份,捕获鼠类397只。所有健康人群血清和鼠类血清样本检测鼠疫F1抗体均为阴性。健康人群钩端螺旋体抗体总阳性率为28.71%,在各乡镇、年龄之间差异均有统计学意义(χ2值分别为854.059、11.520,P<0.01);人群出血热抗体总阳性率为4.63%,在各乡镇、性别、年龄之间差异均有统计学意义(χ2值分别为7.253、6.849、4.808,P<0.05)。鼠类钩端螺旋体抗体总阳性率为4.53%,在乡镇之间差异有统计学意义(χ2=26.436,P<0.01);鼠类出血热抗体总阳性率为13.60%,在乡镇、鼠类之间差异均有统计学意义(χ2值分别为17.579、10.007,P<0.05)。结论钩端螺旋体病与出血热在不同区域的自然感染有差异,应采取有针对性的防控措施,以防止鼠传疾病对人们身体健康的伤害。
Objective To investigate and analyze the natural infection rates of three kinds of rodent diseases at the present stage in Jinyun County between the human and the mouse in order to provide a reference for the next prevention and control work. Methods The epidemiological cross-sectional investigation of three rodent diseases was conducted in three epidemic areas of rodent disease in Jinyun County and three towns in the current high incidence area. Results A total of 627 serum samples were collected from healthy people and 397 mice were captured. All healthy human serum and murine serum samples tested for the detection of plague F1 antibodies were negative. The positive rate of Leptospira antibody in healthy population was 28.71%, with significant difference in all towns and villages (χ2 = 854.059, 11.520, respectively, P <0.01). The total positive rate of the antibody was 4.63% There were significant differences among townships, sexes and ages (χ2 = 7.253,6.849,4.808, P <0.05). The total positive rate of Leptospira antibody in mice was 4.53%, with significant difference between towns (χ2 = 26.436, P <0.01). The total positive rate of hemorrhagic fever antibody in mice was 13.60% There was significant difference between the two groups (χ2 = 17.579,10.007, P <0.05). Conclusion Leptospirosis and hemorrhagic fever in different regions of natural infection are different, we should take targeted prevention and control measures to prevent the rodent disease on people’s health damage.
