HIV/AIDS is a serious health problem that continues to present a significant health concern in underdeveloped nations and may be mostly brought on via unprotected sex. This study is designed and analyzed using a dynamic modeling approach to investigate the dynamic of HIV/AIDS model with vertical transmission and the impact of knowledge on its treatment. Our proposed model exhibit disease free and the endemic equilibrium. The uniqueness and the exactness of the model were investigated and the basic reproduction number using next generation matrix was obtained, Stability analysis was also carried out. The model analysis shows that the disease free equilibrium is locally asymptomatically stable (LAS) when Ro < 1. Our research suggests that treatment and awareness campaigns, when combined with other crucial control measures, may help keep the HIV/AIDS virus from spreading.

Stability analysis of HIV/AIDS epidemic model with nonlinear incidence and treatment2020 •
We propose mathematical model of HIV/AIDS with two different stages of infection subpopulation. The proposed model is more realistic since it establishes the compartment diagram based on data from the Indonesian Ministry of Health. The model consists of six compartments (susceptible, infected with and without treatment, AIDS, treatment, and recovered sub populations). We analyzed the model by proving the positivity and boundedness of the models solutions. Furthermore, we analyzed local and global stability of the solutions determined by the basic reproduction number as a threshold of disease transmission. The disease-free and endemic equilibrium points are locally asymptotically stable when R0 < 1 and R0 > 1 respectively. For global stability, we constructed the Lyapunov function. The results indicate that the diseasefree equilibrium point is globally asymptotically stable when R0 < 1 and that the endemic equilibrium point is globally asymptotically stable when R0 > 1. W...

In this study a non linear mathematical model of HIV/AIDS with treatment, vertical transmission and progression rate was considered. The next generation matrix was used to evaluate the basic reproduction number (R 0) and the comparison approach was used to examine the global stability. The disease – free and the endemic equilibrium of the model were determined. The sensitivity analysis was carried out to determine the parameter that has high impact on the spread of the disease and the maple software was used for numerical simulation of the model. The disease free and endemic equilibrium were obtained and there stabilities studied. The model showed that the disease free equilibrium is locally asymptotically stable by using Routh Hurwitz criteria but globally of the disease free equilibrium is not stable by comparism approach. The numerical simulation shows that by using treatment measures and by controlling the rate of vertical transmission with time, the spread of the disease can reduced significantly and that providing treatment at the pre-AIDs stage reduces the infection much faster than starting treatment after progression into AIDs.

Stability Analysis of the Mathematical Model on the Control of HIV/AIDS Pandemic in a Heterogeneous PopulationHIV/AIDS is a dreaded disease which has over the years claimed the life of so many people both female and male, adult and children in the whole continents or the globe. In this paper, a mathematical model on the control of HIV/AIDS was formulated using; vaccine, condom, therapeutic dose and public health campaign as control measures. The dynamic analysis of the model was carried out and the effective reproduction number R0 obtained. The local and global stability analyses were conducted. From the analysis carried out, we got that…

Stability Analysis of HIV/AIDS Model with Educated SubpopulationWe had constructed mathematical model of HIV/AIDS with seven compartments. There were two different stages of infection and susceptible subpopulations. Two stages in infection subpopulation were an HIV-positive with consuming ARV such that this subpopulation can survive longer and an HIV-positive not consuming ARV. The susceptible subpopulation was divided into two, uneducated and educated susceptible subpopulations. The transmission coefficients from educated and uneducated subpopulations to infection stages were where (( and ) ( and )) In this paper, we consider the case of and were zero. We investigated local stability of the model solutions according to the basic reproduction number as a threshold of disease transmission. The disease-free and endemic equilibrium points were locally asymptotically stable when and respectively. To support the analytical results, numerical simulation was conducted.

This paper considers a non-linear mathematical model for HIV epidemic that spreads in a variable size population through both horizontal and vertical transmission. The equilibrium points of the model system are found and their stability is investigated. The model exhibits two equilibria namely, the disease-free and the endemic equilibrium. It is found that if the basic reproduction number R0 < 1, the disease-free equilibrium is always locally asymptotically stable and in such a case the endemic equilibrium does not exist. If R0 > 1, a unique endemic equilibrium exists which is locally asymptotically stable and becomes globally asymptotically stable under certain conditions showing that the disease becomes endemic due to constant immigration of population into the community. Using stability theory and computer simulation, it is shown that by controlling the rate of vertical transmission, the spread of the disease can be reduced significantly and consequently the equilibrium values of 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 other key parameters on the spread of the disease.

In this paper, we like to propose and analyze a non-linear HIV/AIDS epidemic model with vaccination and antiretrovi-ral therapy. For our convenient study we have divided the total populations into five classes such as susceptible class, unaware HIV infected class, aware HIV infected class, pre AIDS class and AIDS class respectively. For our present purpose we have taken only the disease spread through horizontal transmission into consideration. In this paper we have tried to develop a non-linear HIV/AIDS mathematical model to study the transmission dynamics of HIV at four compartments of the populations with vaccination and antiretroviral therapy and to prove the positivity and bound-edness of its solutions. In this paper we have added a treatment procedure i.e. antiretroviral therapy and tried to find out its effect. We have also analyzed the stability behaviour of the system. Finally we have found that vaccination and antiretroviral therapy is an effective way to control the disea...
