The Comparison Analysis of the Impacts of Lockdown and Quarantine Facets in the Transmission of COVID-19: Mathematical Approach

COVID-19 is the short name of the coronavirus disease discovered in Wuhan, China, in 2019. In the context of Tanzania, we develop a mathematical model in this work that compares lockdown and quarantine. Again, we provide evidence in favor of local and global stability, with the basic reproduction number, R0, determined to be 0.31 at the diagnostic test rates k1=k2=0.05. In comparison to the lockdown, it has been discovered that isolating (or quarantining) affected individuals is the most effective way to stop the spread of COVID-19. Additionally, it is advised that governments in Tanzania and other African countries permit their citizens to go about their daily lives as long as they take the necessary precautions, such as donning face masks, washing their hands, and avoiding crowded gatherings in case of a recurrence of any form of COVID-19. © 2023 Hamenyimana Emanuel Gervas and Alfred K.
