CD4 and infection: In contrast to the “CD4<500” strategy and random (untargeted) TasP, where the final mean incidences were ~0.65 and ~0.3, respectively, incidence in the “under age 30” strategy dropped to less than 0.1 infections/100 person-years in all (16/16) replicate simulations ~15 years after the start of the TasP campaign.
