广州市某医院外科工作人员,于1990年1月份在4天内发生2例流行性出血热(EHF),4天之后又发生1例EHF。经流行病学调查、血清学检测和病毒分离,证实是由实验大白鼠引起的EHF暴发。在与大白鼠接触者中,有咬伤史者EHF感染率显著高于无咬伤史者。
Two surgical cases of epidemic hemorrhagic fever (EHF) occurred in 4 days in January 1990 in Guangzhou City and one case of EHF occurred in 4 days. Epidemiological investigation, serological testing and virus isolation confirmed that EHF outbreaks were caused by experimental rats. In contact with rats, the history of bites with EHF infection was significantly higher than those without bite history.
