Ebola Virus

The Ebola virus disease (EVD; formerly known as Ebola haemorrhagic fever) is caused by infection with Ebola virus which belongs to the family called Filoviridae. EVD in humans has an average case fatality rate of around 50% (varied from 25% to 90% from previous outbreaks). EVD is a severe acute viral illness often characterised by the sudden onset of fever, intense weakness, muscle pain, headache and sore throat. This is followed by vomiting, diarrhoea, rash, impaired kidney and liver function, and in some cases, both internal and external bleeding. Ebola virus is introduced into the human population through close contact with the blood, secretions, organs or other bodily fluids of infected animals.
