Ebola outbreak: 'Death on an almost industrial scale'
A year ago Ebola claimed its first victims in West Africa. Since then around 6,000 people have died, according to World Health Organisation figures, and thousands more have been infected.
But there is a glimmer of hope from the WHO - they had set themselves a target of 1 December- for treating 70% of Ebola patients and burying 70% of victims safely.
They have managed it in Liberia and Guinea but Sierra Leone has failed to meet its target. The BBC's Africa Correspondent Andrew Harding has travelled to the village of Rogbangba to find out why.
