HIV is a retrovirus that infects and im.airs the cells and functions of the im.une system. It has caused a great challenge to global public health system. and leads to Acquired Im.unodeficiency Syndrom. (AIDS), if not attended to in good tim.. Antiretroviral therapy is used for m.naging the virus in a patient’s lifetim.. Som. of the sym.tom. of the disease include lean body m.ss and m.ny opportunistic infections. This study has developed a SIAT m.them.tical m.del to investigate the im.act of inconsistency in treatm.nt of the disease. The arising non-linear differential equations have been obtained and analyzed. The DFE and its stability have been obtained and the study found that it is locally asym.totically stable when the basic reproduction num.er is less than unity. The endem.c equilibrium.has been obtained and found to be globally asym.totically stable when the basic reproduction num.er is greater than unity. Num.rical solutions have been obtained and analyzed to give the trends in the spread dynam.cs. The inconsistency in treatm.nt uptake has been analyzed through the num.rical solutions. The study found that when the treatm.nt rate of those infected increases, it leads to an increase in treatm.nt population, which slows down the spread of HIV and vice versa. An increase in the rate of treatm.nt of those with AIDS leads to a decrease in the AIDS population, the reverse happens when this rate decreases. The study recom.ends that the com.unity involvem.nt in advocating for consistent treatm.nt of HIV to curb the spread of the disease.

A non-linear HIV-TB co-infection has been form.lated and analyzed. The positivity and invariant region has been established. The disease free equilibrium.and its stability has been determ.ned. The local stability was determ.ned and found to be stable under given conditions. The basic reproduction num.er was obtained and according to findings, co-infection dim.nishes when this num.er is less than unity, and persists when the num.er is greater than unity. The global stability of the endem.c equilibrium.was calculated. The im.act of HIV on TB was established as well as the im.act of TB on HIV. Num.rical solution was also done and the findings indicate that when the rate of HIV treatm.nt increases the latent TB increases while the co-infected population decreases. When the rate of HIV treatm.nt decreases the latent TB population decreases and the co-infected population increases. Encouraging com.unities to prioritize the consistent treatm.nt of HIV infected individuals m.st be em.hasized in order to reduce the scourge of HIV-TB co-infection.
