Fig. 4From: Modeling the dynamics of Lassa fever in Nigeria2-D Contour plot of the reproduction number \({\mathcal {R}}_{0}\) of Lassa fever model (1), varying recovery rate of humans with respect to transmission probability rate from humans. Parameter values used are as given in Table 2 except for \(\delta _{h}=0.4887\) so that \({\mathcal {R}}_{0}=0.7461 < 1.\)Back to article page
