"Analysis o a Caputo HIV and Malaria Co-Infection Epidemic Model", Thai Journal of Mathematics, Vol. 19, No. 3, pp. 897-912.1686-0209In this paper, we investigate a fractional-order compartmental HIV and Malaria co-infection epidemic model using the Caputo derivative. The existence and uniqueness of the solution to the proposed fractional-order model were investigated using fixed point theorem techniques. To demonstrate that the proposed fractional-order model is both mathematically and epidemiologically well-posed, we compute the model's positivity and boundedness, which is an important feature in epidemiology. Finally, we analyze the dynamic behavior of each of the state variables using a recent and powerful computational technique known as the fractional Euler method.eninfo:eu-repo/semantics/closedAccessCaputo OperatorExistence And UniquenessMathematical ModelsNumerical SchemeArticle193897912WOS:000691625200013N/AQ4
