In this work, we investigate a mathematical model of COVID-19 for approximate solution through variation iteration method (VIM). With the help of the said technique, we develop an algorithm to compute series type solution to the proposed problem. Then using some real values for the parameters and initial data, we compute few terms approximate solutions corresponding to different compartment. With the help of Mathematica, we also plot our approximate solutions for different compartment graphically.
