A Study of the Hepatitis B Virus Infection Usinghilfer Fractional Derivative

Mathematical models have been used to understand the factors that control infectious disease progression in viral infections. This work considers a fractionalized model for HBV infection treating infected cells. Initially, the Hilfer fractional model has been developed for the epidemic problem. In this article analyzed the fractional form of the model for HBV infection using a numerical technique, i.e., the Laplace homotopy analysis method (LHAM). Homotopy analysis techniques, homotopy polynomials, and Laplace transforms are used to generate the suggested approach. Also, the convergence and uniqueness of the solution are considered. The obtained solutions are graphically simulated through MATLAB. The results obtained can prove helpful in the medical world. The fractional model gives important and relevant inferences to infer new information about the medical field.
