Predicted impact of multifaceted interventions. Contour plot of incidence is represented for different levels of isolation effectiveness (1 − β ₂/β ₁, x-axis) and sporadic acquisition rate (β ₀, y-axis). Increasing incidence values are indicated by ever darker shades of gray, black lines delineate incidence contours with the corresponding threshold value (per 1 000 patient-days). For these simulations, β ₁ was set to 0.006 per day, other model parameters were those in P₁ (Table 1).
