We show that accounting for infection avoidance by susceptible hosts in a host-pathogen interaction significantly alters host population dynamics. In particular, we observe bistability between the disease-free and endemic or disease-induced extinction equilibria, significant abrupt reduction in the host population size and disease-induced host extinction. From the population persistence perspective, the best strategy is either not to avoid mating with the infected individuals, to prevent disease-induced host extinction, or to completely avoid mating with the infected individuals, to prevent pathogen invasion. In addition, we find that increasing sterilization efficiency of the infection leads to lower population sizes and reduced effect of mating avoidance.
