As COVID-19 is becoming endemic with the potential of recurrent epidemics globally, it is a priority to study its transmission dynamics to inform public health decision-making. There are three individual studies conducted to assess COVID-19 disease burden, transmission potential, and to evaluate R packages that are used to estimate a pathogen's transmission potential: 1) estimating the incidence rate ratios of COVID-19 cases among employees of seven District of Columbia government departments, 2) comparing EpiEstim and EpiFilter time-varying reproduction number (Rt) estimation methods using daily reported case count in Hawaii and Guam, 3) comparing the performance of three R packages (EpiEstim, EpiFilter, and EarlyR) that estimate Rt and basic reproduction number (R0) using a discrete-time stochastic S-E-I-R influenza model and a discrete-time stochastic SARS-CoV-2 S-E-P-I-R model simulated epidemic data. The dissertation concludes with a summary and suggestions for future research directions.
