The Ebola virus that has killed thousands in West Africa is still “running ahead” of efforts to contain it, the head of the World Health Organization has said.

Director general Margaret Chan said the situation had improved in some parts of the worst-affected countries, but she warned against complacency.

The risk to the world “is always there” while the outbreak continues, she said.

She said the WHO and the international community failed to act quickly enough.

The death toll in Guinea, Liberia and Sierra Leone stands at 6,331. More than 17,800 people have been infected, according to the WHO.
