For emerging and reemerging mosquito-borne diseases, it is important to understand the conditions and mechanisms triggering an outbreak and recurrence of an endemic. In this talk, I will present bifurcation analysis for dynamical models to explore the threshold conditions and mechanisms for the dynamics for some models of general mosquito-borne diseases. The bifurcations include backward bifurcations, Hopf bifurcations and Bogdanov-Takens bifurcations of codimension two and three, and bifurcation of nilpotent singularities.
