Ebola outbreak in Guinea 'unprecedented' - MSF

The Ebola outbreak that has killed 78 people in Guinea is "unprecedented", a medical charity has said.

An official with Medecins Sans Frontieres (MSF) said the spread of the disease across the country made it very difficult to control.

The West African state is facing a battle to contain the outbreak after cases were reported in areas that are hundreds of kilometres apart.
