Abstract

Rapid transmission of the novel coronavirus and its resulting condition has caught most countries of the world off-guard. This work develops a fractional order model with seven compartments to describe the transmission and effects of control strategies of coronavirus. The Caputo fractional derivative operator of order α ∈ (0,1) is applied to obtain the scheme of fractional differential equations (FDEs) of the model. The stability analysis is carried out and non-negative unique solution within the domain is verified. Laplace–Adomian Decomposition Method is applied to work out an approximate solution of the FDEs. The solution of the FDEs in the form of infinite series is obtained. The obtained results are compared with the differential transform method case, which converges rapidly to its exact value. Numerical simulations are presented to show the reliability and simplicity of the method.
