Ebola spreads through human contact with a sufferer's bodily fluids.
Initial flu-like symptoms can lead to external haemorrhaging from areas like eyes and gums, and internal bleeding which can lead to organ failure.
Ebola kills up to 90 percent of those infected, with patients having a better chance of survival if they receive early treatment.
