The number of deaths from the Ebola epidemic now exceeds 11,000, figures from the World Health Organization showed on Wednesday.
In the three countries worst affected — Sierra Leone, Liberia and Guinea — 26,593 people were infected, and 11,005 had died, the WHO said.
The worst ever outbreak of Ebola began in southern Guinea in December 2013 before spreading to Liberia and Sierra Leone.
Liberia has recorded the most deaths with 4,716, while 3,903 have died in Sierra Leone and 2,386 have died in Guinea.
Although the number of cases has topped 11,000, the WHO is due to declare on May 9 that the epidemic is over in Liberia, unless there are any new cases in the country before then.
The number of new infections are also dwindling in Guinea and Sierra Leone. Only nine new cases were recorded in each country last week, the lowest figures for almost a year.
