The World Health Organization on Friday confirmed a new death from Ebola in Sierra Leone just one 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.
