Using fixed cohorts would increase the effect, but it would never become larger than with the 0% setting." - "Even setting the leisure curfew to 7pm and all other activities to 0% is no longer enough to stop the dynamics unless contact tracing capacities are also approx. tripled." - "Capacity infinity for contact tracing means that current new infection numbers can be handled without additional delay. A delay of 5 days seems realistic for the current situation." - "Many of the changes (schools, other education, day care, shop, errands) have some effect, but it is not large. One would shut down many important activities in order to spare the leisure activities and still not reach R less than one." - "\"Leisure\" refers to private and public spaces; \"curfew\" means that these activities are not allowed during the displayed time range. If only public spaces are included in the measures, i.e. gatherings are still allowed in private spaces, then the effects are roughly halved." - "We give a range for R since point predictions are impossible. We would recommend to have both ends of the range below 1.0 if one wanted to stop the exponential growth."
