Only 27 cases have occurred outside of Sierra Leone, Liberia and Guinea and those three countries account for all but 10 of the fatalities.

The latest report from the health organisation said that Liberia remains the worst affected country with 2,705 deaths recorded. A further 1,281 fatalities have been recorded in Sierra Leone and 926 in Guinea.

Eight deaths have occurred in Nigeria and one in the United States. Mali because the latest country to report a death last week when the virus claimed the life of a two-year-old girl.
