Predicted R\(_{0}\) ratio by country due to physical distancing at work and/or school closure. The impact on R\(_{0}\) is shown with uniform susceptible and infectiousness parameters (1,1,1) and when children are less vulnerable compared to elderly (0.5,1,1.5). The age classes are 0–18 years, 19–60 years and over 60 years of age. Distancing is incorporated by a reduction of location-specific social contacts
