From: Dynamical analysis and numerical assessment of the 2019-nCoV virus transmission with optimal control

The graphical results show the sensitivity analysis of the threshold quantity (\(\mathcal {R}_0\)) and its relative impact against the variations of various epidemic parameters \(\{\beta _1,\beta _2,\alpha ,\sigma ,\eta \}\). For this analysis, the numerical values of the parameters used are \(\beta _1= 0.05\) \(\sigma =0.09871\), \(\eta =0.01\), \(\beta _2=0.00000123\), \(\Pi =0.0033907997\), \(\alpha =0.000398\), \(d_1=0.0404720925\), \(d=0.0003567816\).
