We partition the infection period into four progressive stages: 1. infected but antibody negative; 2. antibody positive but asymptomatic; 3. pre-AIDS symptoms and/or abnormal hematologic indicator; and 4. clinical AIDS.

How adequately a model represents this heterogeneity will substantially determine its accuracy and usefulness for captur

We also present some simulations that illustrate the effects of a changing mean sexual activity in the dynamics of HIV, and formulate a single group model for a heterogeneously mixed population with continuously-distributed sexual activity. This model forms

This paper formulates a model for examining the impact of nonrandom mixing on HIV transmission. We present threshold conditions that determine when H

In order to match the model with data it is assumed that the probability of infection per “encounter” sums over all sexual contacts during a
