Ebola challenge continues in West Africa

The Ebola epidemic continues to pose a massive challenge to Sierra Leone, Liberia and Guinea, the three West African countries at the centre of the crisis.

Joanne Liu, president of Medecins Sans Frontieres (MSF), has told the BBC she cant understand why, seven months after the start of the outbreak, there hasn't yet been a massive deployment of relief teams to West Africa.
