Özet:
A dengue epidemic model with fractional order derivative is formulated to an- alyze the effect of temperature on the spread of the vector-host transmitted dengue disease. The model is composed of a system of fractional order differ- ential equations formulated within Caputo fractional operator. The stability of the equilibrium points of the considered dengue model is studied. The cor- responding basic reproduction number Rα 0 is derived and it is proved that if Rα 0 < 1, the disease-free equilibrium (DFE) is locally asymptotically stable. L1 method is applied to solve the dengue model numerically. Finally, numerical simulations are also presented to illustrate the analytical results showing the inuence of the temperature on the dynamics of the vector-host interaction in dengue epidemics. © 2020 Balikesir University.
