Figure 1 The incidence and severity of HHV-6 viremia in the first 100 days after CBT (N = 125) Nearly all patients reactivated, 77% ≥ 1000, but only 6% > 100,000 and none ≥ 1,000,000.

Figure 2 Relationship between HHV-6 viral load and absolute lymphocyte (ALC) recovery after CBT. There was a significant association between absolute lymphocyte recovery (measured in K/μL) and resolution of HHV-6 viremia. The HHV-6 viral load in the first 60 days post-CBT is shown in black circles and ALC recovery is shown in red stars (all values for all patients). The solid lines are splines over time for HHV-6 viremia (black) and ALC recovery (red), respectively.
