About Ebola: 

Ebola virus disease (EVD), formerly known as Ebola haemorrhagic fever, is a severe, often fatal illness in humans. 

Transmission: The virus is transmitted to people from wild animals and spreads in the human population through human-to-human transmission. 

The average EVD case fatality rate is around 50%. Case fatality rates have varied from 25% to 90% in past outbreaks. 

Prevention: Community engagement is key to successfully controlling outbreaks. Good outbreak control relies on case management, surveillance and contact tracing, a good laboratory service and social mobilisation. 

Treatment: Early supportive care with rehydration, symptomatic treatment improves survival. There is yet no licensed treatment proven to neutralise the virus but a range of blood, immunological and drug therapies are under development.
