A decade ago, the world's eyes were focused nervously on West Africa when Ebola ravaged the region. It left 11,000 people dead in its wake. Now the epidemic is over, does the threat of its return loom and what lessons did the world learn? Arrival of vaccines are a game changer – but new strains can still pose a challenge.

The BBC’s Africa Correspondent Anne Soy tells Mark Lowen what horrors she saw on the ground when the region was struck. And Naomi Grimley, from the Tony Blair Institute for Global Change and former Global Health Correspondent at the BBC, shares what the world learnt from the largest Ebola epidemic in history.
