In bijlage een recent verschenen artikel over de rol van scholen en schoolkinderen bij de verspreiding van SARS-CoV-2 door het RWI – Leibniz-Institut für Wirtschaftsforschung.
“We find that schools play a subordinate role in the spread of SARS-CoV-2, suggesting that the benefits of their closures do not outweigh the costs. The summer school closures do not appear to have had a containing effect on infections in either the school population or older generations. Similarly, an analysis of the impact of fall holiday closures allows us to evaluate whether closures are more effective in more advanced stages of the pandemic. Our results suggest they are not: the fall closures do not appear to have significantly impacted infections among children and adults, although we point out that the confidence intervals for the fall estimates are wider and do not allowus to reject the possibility of sizable effects.In line with our results on school closures, we find concerns about the return to full schoolingcapacity after the summer holidays to be unsubstantiated: infections among children and adults did not rise with the start of the new academic year. Instead, infections appear to increase in the last weeks of the summer holidays and decline in the days after reopening. This pattern is consistent with the view that travel restrictions and testing policies have an impact, although more direct evidence would be needed to reach that conclusion with confidence.”
