"A Coupled Mathematical Model Introducing Biological Control of Dengue"
This work aims to study the dynamical behavior of a dengue epidemics model by introducing biological control. The first model represents the SEIR-SEI model of dengue epidemics and the second model corresponds to coupling a model of biological control. Controlling mosquitoes is considered by an infestation of bacteria that inhibit the transmission of dengue in humans. We determine an analytic expression of replacement ratios that depends on biological control. The results obtained show that the global stability of the disease-free equilibrium is determined by the value of a certain threshold parameter called the basic reproductive number R0 and of the replacement ratios of the biological model RU, RW. The sensitivity analysis shows that the vector to human transmission rate promotes more changes to the biological control system than other parameters. The simulation analysis of the last model showed the efficiency of the biologic control of dengue transmission.
