The effects of awareness and vector control on two strains dengue dynamics

摘要

The aim of this paper is to study the effects of awareness and mosquito control on dengue epidemic. A non-linear host–vector model has been developed to study the dynamics of primary and secondary infection in the presence of two serotypes of dengue virus. The existence and local stability of equilibrium points have been discussed. The global stability of disease-free equilibrium point has been established. The thresholds for both the serotypes have been computed. The mosquito control and awareness parameters decrease the threshold and thereby enhancing the stability of disease-free state.
