Rift Valley Fever Optimal Control: Insecticide Spray, Bed Net and Vaccination

Abstract

A mathematical model for the transmission of rift valley fever was developed and analyzed. The threshold epidemiological pattern of the disease and the equilibriums of the model were determined and the stabilities investigated. A sensitivity analysis of the model was carried out to establish the virtual impact of the model parameters of the spread disease. Optimal control theory was applied to investigate optimal strategies for controlling the spread of rift valley fever using Insecticide Spray, Bed net and vaccination as the control variables. The results obtained from numerical simulation of the model indicated major decline of the transmission of the disease using the three combine control strategies.
