Abstract:
A Mathematical model of a system of non-linear differential equation is developed to study the
transmission dynamics of malaria, dengue and typhoid triple infection. In this work, the basic
reproduction number is derived using the Next Generation Matrix, also we computed the disease free
equilibrium point. The disease free equilibrium (DFE) point is analyzed and was found that the DFE is
locally stable but may be globally unstable when
<1.
