This paper shows that in Germany, schools played a limited role in the transmission of SARS-CoV-2 over the summer and fall of 2020. This finding is consistent with contemporaneous work by Isphording et al. (2021) which also looks at the effect of school closures on the spread of SARS-CoV-2 in Germany in 2020.The paper being discussed here shows an increase in cases just before school re-openings at the end of the summer, probably due to returns from travels. It also highlights that the puzzling finding in Isphording et al. (2021) of a fall in infections after schools re-opened was driven by two states which experienced differential pre-trends.
