The World Health Organization on Friday confirmed a new death from Ebola in Sierra Leone, a day after West Africa celebrated halting the spread of the virus. 

"We can confirm the Ebola case in Sierra Leone," the WHO said in a statement, after a 22-year-old female student was taken ill near the Guinean border and died three days ago, with an initial swab testing positive for Ebola.
