Epidemic hemorrhagic fever has been an ongoing threat to laboratory personnel involved in animal care and use. Laboratory transmissions and severe infections occurred over the past twenty years, even though the standards and regulations for laboratory biosafety have been issued, upgraded, and implemented in China. Therefore, there is an urgent need to identify risk factors and to seek effective preventive measures that can curb the incidences of epidemic hemorrhagic fever among laboratory personnel. In the present study, we reviewed literature that relevant to animals laboratory-acquired hemorrhagic fever infections reported from 1995 to 2015, and analyzed these incidences using fault tree analysis (FTA). The results of data analysis showed that purchasing of qualified animals and guarding against wild rats which could make sure the laboratory animals without hantaviruses, are the basic measures to prevent infections. During the process of daily management, the consciousness of personal protecting and the ability of personal protecting need to be further improved. Undoubtedly vaccination is the most direct and effective method, while it plays role after infection. So avoiding infections can’t rely entirely on vaccination.
