Bovine Tuberculosis (BTB) is a contagious and potentially life-threatening infectious disease of cattle caused by Mycobacterium bovis (M. bovis) that lives in various environment depending on prevailing weather conditions (Temperature and humidity). Globally, the BTB is one of the diseases with utmost public health challenges which places economic and financial burdens on the society. To curb the disease, a mathematical model for the spread of BTB among human and cattle populations including preventive measures was formulated. The model analysis focused on the existence of disease-free and endemic equilibria points and their stabilities. The study used normalized forward sensitivity index method to analyze the model, and results revealed that the most sensitive parameter is the contaminated environment or inter-cattle transmission. Moreover, the study determined the best way of curbing the spread of BTB disease in the human and cattle populations using three interventions: public health education campaign, treatment and vaccination. Subsequently, the study performed numerical simulations whose results affirm the positive effects of a combination of control measures on the magnitude of infections among human and cattle population.
