In modelling the dynamics of the system, the population is divided into four classes namely: HIV negative but susceptibles, HIV infective, HIV infectives that are under therapy and full blown AIDS patients. Positivity and boundness of solutions are analysed quantitatively. Sensitivity indices of the reproductive number ‘ ’to the parameters in the model are calculated. The existence and stability of the disease free and endemic equilibrium points are also analysed. It is found that using Routh Hurwitz criteria, the disease free equilibrium point is locally asymptotically stable when and unstable when . Centre manifold theory is employed to show that the endemic equilibrium is locally asymptotically stable when the reproduction number is less than unity. 0 R 0 1 R0 1R By using computer simulation, it is shown that using therapy (ARVs), the spread of the disease can be reduced significantly and also the equilibrium values of the HIV infective and AIDS population can be maintained at desired levels. A numerical study of the model is also used to investigate the influence of certain key parameters on the spread of the disease. en_US dc.identifier.citation Kanjere, B(2013)Modelling the transmission dynamics of HIV/AIDS with treatment and logistic population growth, Master dissertation, University of Dr es Salaam, Dar es Salaam en_US dc.identifier.uri http://41.86.178.5:8080/xmlui/handle/123456789/7557 dc.language.iso en en_US dc.publisher University of Dar es Salaam en_US dc.subject Aids (Disease) en_US dc.subject Treatment en_US dc.subject Population growth en_US dc.subject Mathematical models en_US dc.title Modelling the transmission dynamics of HIV/AIDS with treatment and logistic population growth en_US dc.type Thesis en_US
