Model fits to viral titers from single-cycle experiments. Model fits to viral titers from single-cycle experiments by (Left) Hale et. al.  (Figure 3A) and (Right) Sugiura and Kilbourne  (Figure 3I). Fitting was performed using an exponential (dot-dashed), delta (dotted), normal (solid) or lognormal (dashed) distribution for the time spent by newly infected cells in the latent state before transitioning to the infectious state. Insets show the same fits and data on a linear virus scale (axis ranges are identical to those in Figure 3).
