本研究证实我省发生的EHF属于野鼠型为主的经典型出血热;疫区分布具有广泛性,但重疫区又有相对的稳定性和局限性,有沿水系分布的特征;同时证实有9种动物携带EHF病毒抗原,黑线姬鼠是野外感染的主要传染源,褐家鼠是居民区感染的主要传染源;并证实潜在疫区的存在。本研究不仅有助于指出我省防治工作的重点及疫情预测的指标,并对尚无病例报告的地区开展预防工作有特别重要的意义,对探讨流行因素,掌握流行规律提供了丰富的资料。
This study confirmed that the EHF occurred in our province belongs to the classical type of hemorrhagic fever dominated by wild-type mice. The distribution of epidemic-endemic areas is widespread. However, there are relative stability and limitations in the epidemic-prone areas with distribution along the river system. 9 kinds of animals carry EHF virus antigen, Apodemus agrarius is the main source of infection in the wild, Rattus norvegicus is the main source of infection in residential areas; and confirmed the existence of potential epidemic area. This study not only helps to point out the key points of prevention and treatment in our province and the indicators of epidemic situation prediction, but also has special significance for prevention work in areas where there is no case report. It provides rich information on exploring epidemic factors and mastering epidemic laws.
