Figure 5

The impact of the cofactor recovery rate on HIV prevalence. A 25 year snapshot of the concentration of infected individuals in the population under the two-patch model with both total and direct transmission rates (black horizontal lines above and below) and under the four-patch cofactor model (in red) with direct transmission and cofactor recovery at rate γ. Dotted lines indicate total population is in decline, solid lines indicate population is growing. Plot constructed from 60 simulations initiated with 1000 individuals, of whom 100 are infected by the primary disease (subpopulation Y, Figure 1b) at time zero and 700 carry the cofactor condition (subpopulation C, Figure 1b) at time zero, over which γ, cofactor recovery rate, was varied.
