An investigation of the prevalence level of Tuberculosis (TB) and malaria in the absence of any intervention strategy (treatment and counseling) for HIV/AIDS individuals when R M and R T is less than unity showed that the prevalence level of the two diseases rise with time. This un- expected rise in prevalence when R M < 1 and R T < 1 is due to the presence of HIV/AIDS. Administration of treatment and counseling for
