Abstract
<p>The fear associated with an infectious disease plays a major role in the management of the infectious disease. Thus, this study tried to assess the impact of fear of infection on the spread of COVID-19 using a mathematical modelling approach. The model considered was shown to have two equilibria points, namely, the COVID-19 free equilibrium (CFE) and the COVID-19 persistent equilibrium (CPE). The computed reproduction number ( R<sub>C1</sub>) was used to validate the local stability of the CPE whenever R<sub>C1</sub> is above one while the CFE is globally asymptotically stable</p>
<p>R<sub>C1 </sub>1. Next, we show that the condition R<sub>C1 </sub>1 is sufficient to halt the spread of COVID-19 by showing that the model possesses forward bifurcation. The sensitivity analysis suggests that the fear of infection does not influence the R<sub>C1</sub> while numerical simulation indicates that the population of all infected humans, COVID-19 deceased individuals and the concentration of the COVID-19 viruses in the environment increases as the fear of infection (<sub>1</sub>) reduces</p>
