Fig. 1. Frequencies of latently infected resting CD4+ T cells in infectious units per million (IUPM) at 24, 48 and 96 weeks of study treatment in infants initiating lopinavir/ritonavir HAART at less than 6 months of age.

Fig. 1

Each circle represents a single measurement per participant. At week 24, all infants with plasma HIV-1 RNA <400 or >2-log drop in plasma viral load below pretreatment levels were included. Measurements on infants initiating HAART at less than or greater than 6 weeks of age [12,13] are shown in red and blue, respectively. Latent reservoir measurements at weeks 48 and 96 are restricted to those infants who maintained suppression (apart from blips) through to week 96 of HAART. IUPM measurements that were below the limit of detection of the assay (IUPM <0.22) are indicated by open symbols. A horizontal line indicates median size of the latent reservoir at each study time point.
