“…One crucial component is incidence function, which can be classified into many different types, such as bilinear type [2], Holling II type [22], Beddington-DeAngelis type [23], and Crowley-Martin type [24]. Many researchers have concentrated on these withinhost models or epidemic models and have obtained some interesting results such as global threshold dynamics [8,9], delay-induced Hopf bifurcation [10,11], competitive exclusion [6,7], traveling wave [12,13], and pattern formation [14][15][16]. Recently, Korobeinikov [25] studied an ordinary differential equation model with general incidence function and dose-dependent parasite reproduction and virulence.…”
