The dynamics of the model in the case whenever \(\mathcal {R}_0<1\) and \(X_0=(9.814987767,0,0,0)\). For this, we use the value of the parameters: \(\beta _1=0.00005\), \(\sigma =0.09871\), \(\eta =0.01\), \(\beta _2=0.0000000123\), \(\Pi =0.093907997\), \(\alpha =0.0398\), \(d_1=0.00404720925\) and \(d=0.009567816\).
