In humans, ebola virus evolution seems to have accelerated still further this may be because particular forms of the virus are adapted to its natural host and tend to predominate, but many forms are able to thrive in a new host lacking effective defence mechanisms. Critical messages are woven through the story so that people better understand ebola, see themselves within the context of an outbreak, and see how to act in ways that can keep themselves safe.
