Key epidemic indicators by ART scenario, over time, enhanced prevention scenario to 2050.

<p>This figure presents key epidemic results. The adult population is the denominator. “Blue” is all CD4 levels, “Yellow” is <500/mm³, “Pink” is <350/mm³, and “Black” is current <200/mm³. The “Incidence rate” graphs show that the rate of new HIV infections drops most sharply with higher ART use due to more inclusive CD4 criteria. The “Prevalence Rate” graphs show a similar but more gradual decline in HIV prevalence with more ART, and also show that differences in ART use in the short term converge over time due to averted infections The “Annual death rate” graph highlights the benefit of expanded ART on death rates.
