The unanticipated continued deep-rooted trend of the Severe Acute Respiratory Syndrome
Corona-virus-2 the originator pathogen of the COVID-19 persists posing concurrent anxiety
globally. More effort is affixed in the scientific arena via continuous investigations in a prolific
effort to understand the transmission dynamics and control measures in eradication of the
epidemic. Both pharmaceutical and non-pharmaceutical containment measure protocols
have been assimilated in this effort. In this study, we develop a modified SEIR deterministic
model that factors in alternative-amalgamation of use of COVID Alert SA app and vaccination against the COVID-19 to the Republic of South Africa’s general public in an endeavor to
discontinue the chain of spread for the pandemic. We analyze the key properties of the
model not limited to positivity, boundedness, and stability. We authenticate the model by fitting it to the Republic of South Africa’s cumulative COVID-19 cases reported data utilizing
the Maximum Likelihood Estimation algorithm implemented in fitR package.
