Jiggers infestation remains a problem especially in areas with limited or no interventions. In this paper, a mathematical model that incorporates media campaigns is proposed with the aim of investigating the potential role awareness through media campaigns on jiggers infestation dynamics. We introduce a class of those that are aware in which the awareness does not completely protect individuals from jiggers. The model analysis is presented in terms of the basic reproduction number. Bifurcation analysis reveals that the model has an intrinsic backward bifurcation whenever the parameter that accounts for the proportion of larvae that develop into adult female fleas involved in jiggers transmission is included. Sensitivity analysis performed and the results suggest that the effective infestation contact rate, as well as the rate at which the larvae develop into adult fleas are the main mechanisms that fuel jiggers infestation. The implications of the result to public health and the management of jiggers infestations are discussed.
