Comparing SARS-CoV-2 case rates between pupils, teachers and the general population: results from Ger-many

Koestner, C.; Letzel, S.; Eggert, V.; Beutel, T.; Dietz, P.

Given the inconsistent state of research regarding the role of pupils and teachers during the SARS-CoV-2 pandemic in Germany, statewide and nationwide data of infection case rates were analyzed to contribute to the discourse. Infection data from official sources ranging from mid to late 2020 were collected, prepared and analyzed to answer the question if pupils, teachers and general population differ in infection case rates or not. Statewide and nationwide data showed that pupils and teachers infection case rates exceeded those of the general population. However, present data do not necessarily indicate that SARS-CoV-2 cases of pupils and teachers infections took place at schools. Actually, data demonstrate an increase of infection cases after vacation, indicating that infections of pupils and teachers might occur during leisure time and not in the school setting. In conclusion, it seems appropriate to reconsider school-related measures to mitigate the SARS-CoV-2 pandemic.
