Timing and pace of scale-up. a Comparison of two scenarios in which a curative intervention becomes available either in 2040 (baseline) or in 2030. b Comparison of different roll-out rates for an intervention in which either 2, 10%, or 20% of eligible HIV-infected individuals are cured per year. In both panels, the y-axis shows the number of individuals aged 15–29 newly infected with HIV per year. The green dashed, blue solid, and purple dotted lines represent the optimistic, neutral, and pessimistic epidemic forecasts, respectively (see Table 1). The symbols on the line denote the alternative scenarios for the cure intervention
