The number of deaths is more than 1,000 higher than the figure issued by the WHO just two days ago, but it is thought to include deaths that have gone unreported in the weeks or months since the outbreak began. Most of the new deaths were recorded in Liberia.
The WHO has warned that its figures could be a significant underestimation of the number of infections and deaths. Data from the outbreak has been patchy and the totals often rise considerably when backlogs of information are cleared. The latest confirmed data shows that almost half those known to have been infected with Ebola have died.
