WHO revises Ebola death toll down

The World Health Organization says it is continuing to see a slowdown in weekly Ebola cases in Liberia, although incidence of the disease is still rising in Sierra Leone and stable in Guinea.

The WHO revised the cumulative death toll downwards for a second week running as it sought to improve the quality of its data, with 440 fewer deaths reported in Sierra Leone than in data published last Friday.

The WHO put the total death toll at 4,818 out of 13,042 cases as of Nov. 2, compared to 4,951 deaths in Friday's Ebola update; but it repeated a warning that the figures continued to be too low because of under-reporting.
