Background and objectives: Despite the decline in new HIV infection across United States, Mississippi is still experiencing high rates of infections. Reports highlighted significant variations by geographical locations socio-demographic factors. This study examined trends HIV/AIDS incidence from 2008 to 2019. Materials methods: Data on diagnosis were extracted Enhanced Reporting System database...

In this paper, an SIR epidemic model with an infectious period and a non-linear Beddington-DeAngelis type incidence rate function is considered. The dynamics of this model depend on the reproduction number R0. Accurately, if R0 < 1, we show the global asymptotic stability of the disease-free equilibrium by analyzing the corresponding characteristic equation and using compa...

       In this paper an SIS epidemic model with saturated incidence rate and treatment func- tion is proposed and studied. The existence of all feasible equilibrium points is discussed. The local stability conditions of the disease free equilibrium point and endemic equilibrium point are established with the help of basic reproduction number.However the global stabili- ty conditions of these eq...
