Ebola crisis: Nigeria officially declared free of virus


Nigeria has been declared officially free of Ebola after six weeks with no new cases, the World Health Organization (WHO) said on Monday.

The Western African country, Africa's most populous nation, won praise for its swift response after an infected Liberian diplomat brought the disease there in July.

The news comes after the WHO officially declared Senegal Ebola-free on Friday.

The current Ebola outbreak has killed more than 4 500 people in West Africa, mostly in Liberia, Guinea, and Sierra Leone.

An estimated 70% of those infected have died in those countries.

Earlier, the Spanish government said a nurse who became the first person to contract Ebola outside West Africa had tested negative for the virus.
