Transmission population-attributable fraction (direct and indirect transmission) estimated for people with HIV of different diagnosis and treatment stages.

Estimated transmission population-attributable fraction (tPAFs) of members of key populations (KP) living with HIV with undiagnosed infection (pink boxes and intervals), All PWH with undiagnosed infection (red), with diagnosed infection but not on antiretroviral therapy (ART) (blue), and on ART (green) over successive decades. Boxes represent median and interquartile range, whereas error bars represent 90% uncertainty interval (UI) (5th and 95th percentiles) of tPAF estimates across all posterior parameter sets. KP include female sex workers, their clients, and MSM.
