Figure 3: Three sets of scatterplots describing simulated outbreaks of influenza, norovirus and measles are shown.

Individual scatterplots provide a cross section of possible outbreaks where rows hold β ranges constant while columns hold γ ranges constant. Plots show λ values on the y-axis, control start (τ) values on the x-axis and are colored by κ ranges. Each point denotes a counterfactual (i.e., a controlled outbreak within the given β and γ ranges compared to an identical uncontrolled outbreak). The color indicated the κ score associated with the counterfactual trial. Gray points are combinations that yield no outbreak (defined here as fewer than 2 cases overall), and progressively darker shades of blue indicate less difference between the controlled and uncontrolled outbreak.
