Numerical study on fractional order nonlinear SIR-SI model for dengue fever epidemics

Abstract This paper focuses on a combined SIR-SI epidemic model to evaluate the transmission dynamics of dengue fever, integrating the susceptible-infected-recovered (SIR) framework for the human population with the susceptible-infected (SI) framework for mosquitoes. The model is formulated as a sys...
