Ebola Virus Ecology Graphic

This graphic shows the life cycle of the ebolavirus. Bats are strongly implicated as both reservoirs and hosts for the ebolavirus.

Of the five identified ebolavirus subtypes, four are capable of human-to-human transmission.


Initial infections in humans result from contact with an infected bat or other wild animal.

Strict isolation of infected patients is essential to reduce onward ebolavirus transmission.
