GENEVA, Nov 12 (Reuters) - The death toll from the Ebola outbreak in West Africa's three hardest-hit countries, Guinea, Liberia and Sierra Leone, has risen to 5,147 out of 14,068 cases at the end of Nov. 9, the World Health Organization (WHO) said on Wednesday.
A further 13 deaths and 30 cases have been recorded in five other countries - Nigeria, Senegal, Mali, Spain and the United States, the U.N. agency said.
"There is some evidence that case incidence is no longer increasing nationally in Guinea and Liberia, but steep increases persist in Sierra Leone," the WHO said in a statement. "Cases and deaths continue to be under-reported in this outbreak."
Some 421 new infections were reported in Sierra Leone in the week to Nov. 9, especially in the west and north, while there have been a total of four confirmed and probable cases in Mali and four deaths, it said.
More than 90 people were quarantined across the Mali capital on Wednesday after a 25-year-old nurse died of Ebola after treating a Guinea man who died after showing Ebola-like symptoms.
Only 19 of 53 Ebola treatment centers planned in the three countries with intense transmission of the virus are in operation, the WHO said. (Reporting by Stephanie Nebehay; Editing by Andrew Roche)
