Epidemics result from person-to-person contact within communities, families, and hospitals, or from inadvertent laboratory exposures. The means of infection and the natural ecology of these viruses are largely unknown, although an association with monkeys and/or bats has been suggested.

Ebola virus disease (formerly known as Ebola haemorrhagic fever) is a severe, often fatal illness, with a death rate of up to 90%. The illness affects humans and nonhuman primates (monkeys, gorillas, and chimpanzees). Ebola first appeared in 1976 in two simultaneous outbreaks, one in a village near the Ebola River in the Democratic Republic of Congo, and the other in a remote area of Sudan. The origin of the virus is unknown but fruit bats (Pteropodidae) are considered the likely host of the Ebola virus, based on available evidence.
