Transmission of Ebola virus (EBOV) in Ebola virus disease (EVD) outbreaks compared to virus transmission in other zoonotic viral hemorrhagic fevers. EVD outbreaks usually result from exclusively human-to-human transmission following a single zoonotic spillover to a primary EVD case. Outbreaks of other zoonotic viral hemorrhagic fevers are often characterized by sustained spillover from a reservoir/intermediate host and limited human-to-human transmission. *Other filovirus diseases (e.g. Marburg virus disease) follow a similar pattern to EVD.
