Computation of SEIR model of outbreak virus using RK4 method
(UMT Lahore, 2023-08) Zahrah Fatima; Kinza Shahzadi
In this study, we formulate the mathematical model of COVID-19 with the effects of partially and fully vaccinated individuals. Here, the purpose of formulating the model is to study these models numerically. It is very complex to solve the four equations of the SEIR model, so we use the fourth-order Runge-Kutta method to solve those equations. This method is very efficient and practically suited for solving initial value problems. That’s why we formulated the SEIR model with the incorporation of fully and partially vaccinated parameters. Then we try to solve our equations by converting them into the fourth-order Runge-Kutta method. Moreover, to make the model more realistic, we assume the outbreak of COVID-19 in Bangladesh. We used Python for simulation purposes.
