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 variation of various epidemic parameters \(\beta _1\). We use the numerical values of other parameters \(\Pi =0.0033907997\), \(\alpha =0.000398\), \(d_1=0.0404720925\), \(d=0.0003567816\).
