Impact of screening at admission. Contour plot of incidence is represented for different levels of admission prevalence (σ, x-axis) and isolation rate of imported cases (δ ₁, 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, model parameters values were those estimated or fixed in P₁ (Table 1).
