This is a map by Centers for Disease Control and Prevention on Ebola Hemorrhagic Fever outbreaks by species and size in various countries across Africa, 1976-2014.

An outbreak of Ebola virus disease (EVD) in West Africa, with onset in early February 2014, is evolving in Guinea and Liberia. This is the first such outbreak in the area. The first cases were reported from the forested region of south-eastern Guinea.

Using S-I-R and S-E-I-R models, it was possible to simulate two Ebola outbreaks: the 1976 outbreak in Yambuku, Zaire and the 1995 outbreak in Kikwit, Zaire. The dynamics of these models are determined by the per-capita death rate of infected individuals and the per-capita effective contact rate of an individual contracting the disease.
