Ebola virus disease is transmitted from human to human through physi- cal contact of body uid of infected or dead case. It can also be transmitted indirectly through contact with contaminated surfaces. This risk is however low and can be minimised through cleaning the surfaces by the use of disin- fectants. In this paper we investigate the transmission dynamics of the 2014 Ebola virus disease in west Africa. We use a four compartmental network of Susceptible individuals (S), Exposed individuals (E), Infectious individuals (I) and the Removed individuals (R) without demographic factors. The re- moved compartment is further split into two compartments i.e the recovered individuals (R) and the dead and buried individuals (D). We give the math- ematical model that describe the transmission dynamics of the 2014 Ebola virus disease in West Africa. The results of the model analysis indicate that the threshold value for the transmission dynamics equals the relative removal rate. It is shown that provided that the susceptible ratio is kept below the relative removal rate then the epidemic will not occur.
