Federal University of Technology, Owerri, Nigeriahttps://repository.futo.edu.ng/handle/20.500.14562/1809This thesis is for the award of Master of Science (MSc.) in Applied MathematicsA model for Chlamydia trachomatis (CT) and gonorrhea co-dynamics is studied and analysed to assess the impact of targeted treatment for each of the diseases on their co-infections population. The model exhibits the dynamical feature of backward bifurcation when associated reproduction number is less than unity. The global asymptotic stability of the disease-free equilibrium was also analyzed. The numerical simulations show that the strategy which implements female chlamydia trachomatis treatment and male gonorrhea treatment is the most effective in combating co-infections Chlamydia trachomatis and gonorrheaenAttribution-NonCommercial-ShareAlike 4.0 InternationalChlamydiatracchomatisgonorrhoeastabilityoptimal Control.Department of MathematicsMaster’s Thesis
