Figure 3

Figure 3. Probability distribution of attack detection delay for a contagious agent. Blood donations occur at rate k=0.05 per person per year, the screening test has a mean window period of ω=3 days, the reproductive number R0=3, the mean duration of infectiousness r-1=14 days, and initial attack sizes range from 100 through 1,000 infections.
