    Model for HIV Infection and Data Base
    (Journal of International Research in Medical and Pharmaceutical Sciences, 2015-08) Pokhariyal, G. P.; Rodrigues, A. J.; Mungai, A.; Simwa, Richard Onyino; Njui, F.; Moindi, S. K.
    In this paper the development of HIV infection and its different stages are described first by medical stages. By making use of the differential equations, model for various stages and the growth of HIV infection has been constructed and its implicit solution is obtained. The results are interpreted in terms of the parameters and their relationships are established. The control conditions are derived analytically and treatment options are suggested that need to be adopted, when the expected maximum tolerable HIV infection proportion pt (I) is less than the level off value L of the infection proportion in the patient. Finally the data base development

    On Empirical Modelling of HIV/AIDS Pandemic with Application to East Africa
    (African Journal of Science and Technology, 2003) Simwa, Richard Onyino; Pokhariyal, G. P.
    A number of models have been proposed to study the projections of Human Immunodeficiency Virus (HIV)/acquired immunodeficiency syndrome (AIDS) epidemic in sub-Saharan Africa. In this paper we propose the use of statistical approaches, curve fitting and back projection, which have been widely applied in projecting the HIV/AIDS epidemic in the developed countries. The reported data on the annual incidences of AIDS diagnoses for both Kenya and Uganda are used to determine trend patterns of the expected HIV/AIDS epidemic in the two countries. The results are quite similar to those obtained using the behavior based dynamical compartmental (or demographic) models on the same epidemic
