Dynamics and Transmission of COVID-19 Epidemic in Malaysia: Atangana-Baleanu Fractional Model.

The purpose of this article is to specify the passage and mathematical model of COVID-19. The infectious disease COVID-19 originated in China and has affected the whole world. In the present study, we have considered, the SEIR model to evaluate the spread of COVID-19 in Malaysia. In this article, we have explored the gesture of COVID-19 accurately by applying the newly advanced fractional operator of Atangana-Baleanu to the classical SEIR model. Based on (WHO) reported data in this study, we discussed the corona's virus's behaviour in Malaysia. We have taken the available infection cases from 1st May 2020 to 14th May 2020. We have matched our problem to Malaysia's actual data, which shows a firm agreement with the actual data. Based on data gathered by the World Health Organization (WHO), we have determined the basic reproduction number for the studied disease. Furthermore, we conducted a stability analysis for both the Disease Free Equilibrium (DFE) and the Endemic Equilibrium (EE) in order to understand the behavior of the model in terms of disease spread and persistence. The fractional model provided was solved through numerical methods using MATLAB software. We visually depicted and extensively discussed the impact of various parameters. Notably, our study projected the disease progression for the next 300 days through an approximation. [ABSTRACT FROM AUTHOR]
