Abstract: Trichomoniasis is a sexually transmitted disease caused by an infection from the parasite Trichomonas vaginalis. A model of its transmission shows a backward bifurcation when the basic reproduction number $${{\mathcal R}_0}$$R0 is less than one. A stable disease-free equilibrium co-exists with a stable endemic equilibrium with the consequence that the disease may invade the population even when $${{\mathcal R}_0} \lt 1$$R0 1. Contact rates are the major parameters in the persistence of the disease, compared to rates of recovery after treatment, infectiousness of asymptomatic individuals, and rates of reinfection.
