Prevalence of the infection with the wild-type pathogen. Equilibrium prevalence of the infection with the wild-type pathogen (\({P}_{W}^{*}=\frac{{I}_{W}^{*}}{N}\)), as a function of the frequency of resistant hosts \({f}_{R}\) for three different values of \({R}_{RW}\), \({R}_{NW}=1.5\), such that the endemic prevalence of the wild type in a fully non-resistant population is 0.33 (Eq. 5). For \({R}_{RW}=0.8\), the fractions of infected resistant (\({P}_{RW}^{*}=\frac{{I}_{RW}^{*}}{N})\) and non-resistant (\({P}_{NW}^{*}=\frac{{I}_{NW}^{*}}{N}\)) hosts are also shown
