The Ebola outbreak in West Africa was first reported in March 2014, and has rapidly become the deadliest occurrence of the disease since its discovery in 1976.

In fact, the current epidemic sweeping across the region has now killed more than all other known Ebola outbreaks combined.

Up to 4 November, 4,960 people had been reported as having died from the disease in five countries; Liberia, Guinea, Sierra Leone, Nigeria and the United States. A further death has been reported in Mali.

The total number of reported cases is in excess of 13,000.

The World Health Organization (WHO) admits the figures are underestimates given the difficulty collecting the data and warns there could be as many as 20,000 cases by the end of November if efforts to tackle the outbreak are not stepped up.
