Ebola hemorrhagic fever (EHF) is an acute hemorrhagic infectious disease caused by Ebola virus (EBOV). Human is infected via contacts to body fluid, secretions, and discharges from patients or infected animals. Its clinical manifestations include fever, bleeding, and multiple organ lesions. It has a high mortality rate, which is up to 50–90 %. WHO ranked EBOV as one of the biosafety level 4 viruses that are most life-threatening. Related experimental procedures should be performed in the highly safe BSL-4 laboratories.
