目的 :探讨洪涝灾害地区肾综合征出血热 (HFRS)发病特点 ,为制订控制对策提供依据。方法 :在灾期及灾后对灾区实施鼠情监测 ,同时收集分析 1998、1999年度疫情资料。结果 :洪涝灾期灾区鼠密度、鼠带病毒率、鼠感染率均明显上升 ,疫区疫源地传染强度增大 ,局部灾区已存在HFRS暴发的危险因素。结论 :通过加强对灾区的疫情、鼠情监测和及时采取有效的控制措施 ,可以控制HFRS暴发流行
Objective: To investigate the incidence of hemorrhagic fever with renal syndrome (HFRS) in flood-prone areas and provide evidence for the development of control strategies. Methods: Rodent surveillance was performed on the affected areas during the disaster and after the disaster, and epidemic data of 1998 and 1999 were also collected and analyzed. Results: The rat density, rat virus and mouse infection rates in flood-affected areas were significantly increased, and the infectious intensity in the epidemic areas increased. Some risk factors for HFRS outbreaks were found in some affected areas. Conclusions: HFRS outbreaks can be controlled by strengthening the epidemic situation in quake-stricken areas, monitoring of rats and taking timely and effective control measures
