Numerical Modeling for Transmission Dynamics of Hepatitis B Virus Disease

Numerical modeling of communicable disease is a device to appreciate the instrumentin what waysyndrome pushovers and in what waystately. we have studied numerically the dynamics of HBV. We frame an entirelyconstant Non-Standard Finite Difference (NSFD) structurefor a mathematical model of HBV. The introduce numerical array is bounded, dynamically designate and contain the positivity of the solution, which is one of the important requirements when modeling a prevalent contagious. The comparison between the innovative Non-Standard Finite Alteration structure, Euler method and Runge-Kutta scheme of order four (RK-4) displays the usefulness of the suggested Non-Standard Finite Alteration scheme. NSFD scheme shows convergence to the exact equilibrium facts of the model for any time steps used but Euler and RK-4 fail for large time steps.
