Sensitivity analysis of the basic reproduction number \({\mathcal{R}}_{0}\) with respect to model parameters. Baseline values used given in Table 2. The exact numerical indices are also presented in Table 1, whereas control parameters are set to \(u_{E}=u_{L}=u_{P}=u_{A}=0.3\). Overall, we can note that model parameters b and W are highly correlated with \({\mathcal{R}}_{0}\). In particular, an increase in either b or W by 10% may result in an increase in the magnitude of \({\mathcal{R}}_{0}\) by 10%
