Abstract We consider a deterministic mathematical model to study the role of Information on the dy- namics of Typhoid Fever. We analyse the model to study its boundedness and compute the threshold value known as basic reproduction number for determination of number of secondary cases and establishment of the the condition for local and global asymptotic stability of th sta- tionary points. The numerical simulation is used to depict dynamical behaviour of Typhoid Fever in the considered population. The results indicate a clear role of information in influ- encing a behaviour change that may in a way lead to an increase in the transmission typhoid fever. The result further show that the increase of the number of individuals with Typhoid fever is greatly influenced by failure of the people to follow health precaution that reduce the spread of the disease. The result necessitate the importance of the government to continue educating and/or giving information to her people on the behaviour that in one way or another may lead to the increase of the transmission of typhoid fever which should also be an importance topic to be discussed when planning for any control strategies against the disease. 1 Introduction Typhoid fever is an exclusively human enterically transmitted systemic disease caused by infec- tion with the bacterium Salmonella enterica serovar Typhi. Although largely controlled in Eu- rope and North America, typhoid remains endemic in many parts of the world, notably Africa, where it is an important cause of febrile illness in crowded, low-income settings (Shaikh and Nisar, 2019). The infection is often passed through contaminated food and drinking water, and it is more prevalent in the places where hand-washing is less frequent. Moreover, it can be transmitted to the susceptible human being through adequate contact with the infected person. 1 arXiv:2310.09825v1 [math.DS] 15 Oct 2023
