Table 2 Probability (means ± SD) of HCV transmission as a function of viral load.To estimate the probability of HCV transmission (Eq. 1), means were calculated using a Monte Carlo procedure. For parameter ρ (Eq. 1), samples were generated using the truncated normal distribution with the SD equal to one-quarter of the experimentally determined range. For parameter *s*, values were chosen from a uniform distribution between 0.05 and 0.5, and *q* values were chosen from a gamma distribution with calculated median and Q1 to Q3 as 17% and 7 to 33%, respectively (table S2).
