(Bloomberg) – Lab tests confirm that the Ebola virus has killed a patient in Sierra Leone.
Public health authorities believe the virus has also caused four other deaths in that country, the World Health Organization said in a statement.
Sierra Leone has become the third country to report Ebola deaths since March.
Authorities have recorded 258 Ebola infections in Africa since March and 174 Ebola-related deaths.
The outbreak seemed to be waning, but now the affected area appears to be expanding.
Inside Guinea, officials have reported eight Ebola cases and three deaths in the Telimele district. The district has not previously reported any cases of Ebola, WHO officials said.
