But WHO warned there could still be flare-ups of the disease in the region, which has suffered the world’s deadliest outbreak over the past two years, as survivors can carry the virus for many months and could pass it on.
But two tests conducted on a boy who died in northern Sierra Leone proved positive for the virus, a health ministry.
Health officials say the boy had died in the northern Tonkolili district. The tests were conducted by British health experts.
Health specialists cautioned against complacency, saying the world was still underprepared for any future outbreaks of the disease.
Close to 4,000 people died of Ebola in Sierra Leone, and 11,000 people across the region, since December 2013.
