Ebola virus disease (EVD) (or Ebola hemorrhagic fever (EHF)) is the name for the human disease which may be caused by any of four of the five known ebolaviruses. These four viruses are: Bundibugyo virus (BDBV), Ebola virus (EBOV), Sudan virus (SUDV), and Taï Forest virus (TAFV, formerly and more commonly Côte d'Ivoire Ebolavirus (Ivory Coast Ebolavirus, CIEBOV)). EVD is a viral hemorrhagic fever (VHF), and is clinically nearly indistinguishable from Marburg virus disease (MVD).

Ebola virus (EBOV) causes severe disease in humans and in nonhuman primates in the form of viral hemorrhagic fever. EBOV is a select agent, World Health Organization Risk Group 4 Pathogen (requiring Biosafety Level 4-equivalent containment), National Institutes of Health/National Institute of Allergy and Infectious Diseases Category A Priority Pathogen, Centers for Disease Control and Prevention Category A Bioterrorism Agent, and listed as a Biological Agent for Export Control by the Australia Group.
