Schematics of equilibria at different values of Rc. a Rc less than the bifurcation, \(R_{c}^{*}\) (occurs in Fig. 2a–c); b \(R_{c} > R_{c}^{*}\), without bistability (occurs in Fig. 2a, b); c \(R_{c} > R_{c}^{*}\), with bistability (occurs in Fig. 2c). \(p_{df}^{*}\) is the disease-free equilibrium which is stable in a and c, and unstable in b; \(p_{uns}^{*}\) is an unstable equilibrium; \(p_{end}^{*}\) is an endemic stable equilibrium
