Abstract
TB is a disease caused by bacteria called "Mayco Bacterium", when AIDS is
caused by HIV virus. In this research a non linear models for TB and HIV
co-infection have been studied. The study include presenting conditions for
positivity and boundedness of solutions. The study also established conditions
for the local and global stability of the sub-models and the full model. Using
ode45 of MATLAB numerical simulations has been presented for different
parameter values. Sensitivity Analysis has been studied for the model parameters
and has shown that the probability of being infected of TB and the contact
rate are most sensitive parameters of the spread of disease, and m, B are less
sensitive parameter of the spread of disease.
