Role of fractional derivative order in a model for the spread of HIV/AIDS epidemic

In this paper, we present a fractional model for transmission dynamics of HIV/AIDS with screening, and investigate the e cacy of the fractional derivative order (0:6 < 1) on the spread of HIV/AIDS epidemic using the Adams type predictor-corrector method. The numerical results show that the derivative order can play the role of precautions against infection transmission, treatment of infection and delay in accepting HIV testing.
