  This paper investigates the dynamics of Ebola virus transmission in West
Africa during 2014. The reproduction numbers for the total period of epidemic
and for different consequent time intervals are estimated based on a newly
suggested linear model. It contains one major variable - the average time of
infectiousness (time from onset to hospitalization) that is considered as a
parameter for controlling the future dynamics of epidemics.
  Numerical implementations are carried out on data collected from three
countries Guinea, Sierra Leone and Liberia as well as the total data collected
worldwide. Predictions are provided by considering different scenarios
involving the average times of infectiousness for the next few months and the
end of the current epidemic is estimated according to each scenario.
