摘要: 目的调查内蒙古自治区锡林郭勒盟是否存在肾综合征出血热(HFRS)疫源地。方法 HFRS病例个案调查、人群感染率调查、宿主动物分布及其汉坦病毒抗原和抗体检测。结果当地健康人群HFRS抗体阳性率为6.25%(4/64);居民区鼠的HFRS抗体阳性率为12.00%(3/25);野外鼠的HFRS抗体阳性率为19.64%(11/56)、抗原阳性率为6.35%(4/53)。结论首次证实锡林郭勒盟存在HFRS疫源地。

Abstract: Objective To determine whether the focus of hemorrhagic fever with renal syndrome (HFRS) existed in Xilin Gol league, and provide scientific evidence for the prevention and control of HFRS. Methods Case study of HFRS, infection rate survey, and host animal distribution and hantavirus antigen and antibody detections were conducted. Results The detection rate of HFRS antibody in local healthy population was 6.25% (4/64); the detection rate of HFRS antibody among the rats in residential area was 12.00% (3/25); and the detection rate of HFRS antibody among wild rats was 19.64% (11/56), the antigen positive rate was 6.35% (4/53).
