Future of Mathematical Modelling: A Review of COVID-19 Infected Cases Using S-I-R Model

The spread of novel coronavirus disease (COVID-19) has resulted in chaos around the globe The infected cases are still increasing, with many countries still showing a trend of growing daily cases To forecast the trend of active cases, a mathematical model, namely the SIR model was used, to visualize the spread of COVID-19 For this article, the forecast of the spread of the virus in Malaysia has been made, assuming that all Malaysian will eventually be susceptible With no vaccine and antiviral drug currently developed, the visualization of how the peak of infection (namely flattening the curve) can be reduced to minimize the effect of COVID-19 disease For Malaysians, let's ensure to follow the rules and obey the SOP to lower the R0 value from time to time, hoping that the virus will vanish one day © 2021 University of Baghdad All rights reserved
