Figure 3. Modeling the Probability of SARS-CoV-2 Introduction Into a Day Care Center (DCC).

For the probability of at least 1 child with SARS-CoV-2 (ie, primary case) entering the DCC within 1 week to remain below or at a maximum level of 5%, the age-adjusted incidence must be less than 143, 95, and 71 for DCC sizes of 50, 75, and 100, respectively. The right panel shows the blue rectangle in the left panel in more detail.
