In this paper we present a model for dengue disease transmission with an assumption that individuals in the under-laying populations experience a monotonically non-increasing survival rate. We show that there is a threshold for the disease transmission, below which the disease will stop (endemic equilibrium is not appearing) and above which the disease will stay endemic (endemic equilibrium is appearing). We also investigate the stability of this endemic equilibrium.
