An AIDS-free generation?

ON THE STABILITY AND THRESHOLD ANALYSIS OF AN EPIDEMIC MODEL

We consider a mathematical model of epidemic spread  in which the  population  is partitioned  into five compartments of susceptible S(t), Infected I(t), Removed R(t), Prevented U(t) and the Controlled W(t). We assume each of the compartments comprises of cohorts of individuals which are  identical with respect to the disease status. We derive five systems of equations to represent each of the ...

Stability Analysis of a Fractional Order Model of HIV virus and AIDS Infection in the Community

In  this  paper a  non-linear  model  with  fractional  order  is  presented  for  analyzing  and  controlling the  spread  of  HIV virus.  Both  the  disease-free  equilibrium and the endemic equilibrium are  found  and  their  stability is  discussed. The basic reproduction number , which is a function of the constant parameters in the model, plays an essential  role in the stability of  the ...

An epidemic model for the transmission dynamics of HIV/AIDS with different clinical stages

In this paper, a five–dimensional mathematical model is proposed for the transmission dynamics of HIV/AIDS within a population of varying size. In writing the model, we have divided the population under consideration into five sub classes of susceptible, infective, pre-AIDS, AIDS related complex and that of AIDS patients. The model has two non- negative equilibria namely, a disease free and the...

World AIDS Day — December 1, 2017

World AIDS Day draws attention to the current status of the human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) epidemic worldwide. The theme for this year's December 1 observance is "Shared Responsibility: Strengthening Results for an AIDS-Free Generation."

The prospect of a generation free of HIV may be within reach if the right policy decisions are made.

Scientific advances have transformed HIV treatment and prevention, leading to the adoption of an approach that emphasizes broad testing and antiretroviral treatment at earlier stages in the disease, called "test and treat." In addition to clinical benefits, early treatment generates considerable social and economic value. These changes raise the prospect that for the first time since the 1980s,...
