COVID-19 is an infectious disease respiratory acute coronavirus syndrome. Malaysia had 4,201,919 total cases as of March 31, 2022, with Selangor having the highest number of cases (10,735). Despite the government’s efforts, the highly contagious disease has affected people from all walks of life, and the number of daily cases continues to increase. The objective of this study is to identify the factors that are significantly associated with the daily total COVID-19 cases. The variables that were tested using Negative Binomial Regression were mass testing, vaccination, temperature, and Movement Control Order (MCO). As the result, all predictor variables—except for vaccination—are significantly associated to the number of COVID-19 cases. From this study, the policymakers can utilize the research’s findings to identify the variables that influence the number of COVID-19 cases on a day when the number is very high or low, or when the number is constant for a while before a shift in trend occurs.
