Figure 5. Characterization by CD4+ specific immunogenic potential, Inline graphic.

Figure 5

Outcomes of secondary infection for all possible combinations of time of primary infection Inline graphic and time of secondary infection Inline graphic (constraining Inline graphic), sampled with a step of 2 years (hence the pixel-like appearance of the graphs). All graphs in the figure have the same y axis, whose label is reported in the leftmost graph only. All parameters of the immune models are kept fixed at the same baseline values (see Table S1 in File S1), and the aging rate Inline graphic is set to 0.05 yearsInline graphic; The CD4+ specific immunogenic potential Inline graphic varies with the panels. Dark red: active disease; orange: LTBI followed by endogenous reactivation at some point of the host’s life; turquoise: clearance of primary infection.
