Ebola briefly returned to the headlines this week with a scare at a hospital in New York, but the deadly virus continues to claim victims in West Africa, dealing a devastating social and economic blow to some of the world's poorest countries.
However, the epidemic, which is now in its second year, has also highlighted the surprising resilience of other nations in the region.
"The public is not always aware of what's happening in West Africa, but we're still seeing 20 to 30 new cases of the disease in Sierra Leone and Guinea every week and Liberia had a resurgence recently," Kent Brantly, an American doctor who survived Ebola after contracting it from patients in West Africa, told CNBC on Tuesday.
Although the epidemic has waned from its peak at the end of last year, when hundreds of new cases were diagnosed every week, it has so far proved impossible to eradicate completely. Concerns exist that the epidemic may never be fully eliminated.
