The disease typically occurs in outbreaks in tropical regions of Sub-Saharan Africa.[1] From 1976 (when it was first identified) through 2013, fewer than 1,000 people per year have been infected.[1][4] The largest outbreak to date is the ongoing 2014 West Africa Ebola outbreak, which is affecting Guinea, Sierra Leone, Liberia and likely Nigeria.[5][6] As of August 2014 more than 1600 cases have been identified.[7] Efforts are ongoing to develop a vaccine; however, none yet exists.[1]
