Estimating active cases of Covid-19 post-school reopening in Malaysia using S-I-R modelling.

As of March 2022, there have been 3,116,564 infections and 32,827 coronavirus-related deaths reported in the country since the pandemic began on 1st March 2022. This drastic increase in numbers has been alarming everyone. Malaysia has successfully handled the first and second waves of the COVID-19 cases. However, the recent wave of omicron variants in Malaysia sees a massive increase in COVID-19 infections. Therefore, forecasting plays a vital role in determining preparedness for the current pandemic. This study aims to understand the behaviour of the current infection trend and provide valuable information to the authority to prevent future spikes of active cases. In this paper, the SIR model (Susceptible - Infected Recovered) was used to estimate the active cases in Malaysia. This forecast is essential to prepare for the current wave outbreak. Besides that, the number of susceptible can be reduced via vaccinations to reduce future outbreaks. Therefore, with proper planning and execution, the inoculation rates in Malaysia proved to be successful, and the impact of mass vaccination would be seen in future. [ABSTRACT FROM AUTHOR]
