Numerical Modelling of Influenza Model with Diffusion

Atit Jaichuang and Wirawan Chinviriyasit

Abstract—The SEIR model for the transmission dynamics of influenza is extended by the addition of second-order space derivatives to enable the geographic spread of the disease in a population which has not been vaccinated against it. The resulting system of four reaction-diffusion equations is solved by a convergent finite-difference technique which is first-order accurate in time and second-order accurate in space. The resulting methods are analyzed for local truncation errors and stability. The numerical results verify that the proposed method is more competitive in terms of numerical stability than the standard finite-difference method.

Index TermsSEIR model, reaction-diffusion system, finite-difference method, initial condition, influenza, infectious diseases.
