Abstract
Typhoid fever is one of the diseases that is affecting humanity globally especially in the developing countries where access to clean environment and food are limited. We formulate a dynamical system model to study the effects of multiple control measures (i.e, vaccination, treatment and environmental sanitation) in mitigating typhoid fever disease. The qualitative analysis of our model was carried out accordingly. The impact of introducing the control measures were estimated using appropriate mathematical analysis and numerical simulations.
