Abstract
As record cases due to the Omicron variant are currently registered in Europe, schools remain a vulnerable setting suffering large disruption. Extending previous modeling of SARS-CoV-2 transmission in schools in France, we estimate that at high incidence rates reactive screening protocols (as currently applied in France) require comparable test resources as weekly screening (as currently applied in some Swiss cantons), for considerably lower control. Our findings can be used to define incidence levels triggering school protocols and optimizing their cost-effectiveness.

Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:Our study has limitations. We did not fit the model to the Omicron wave in a specific country, as we aimed to evaluate protocols’ resources and impact in a range of high incidence conditions experienced across countries in Europe. Nonetheless, the model follows the observed dynamics in France. With remaining uncertainty on Omicron features, we assumed that its higher spreading rate was mainly due to immune evasion12, in line with observations from household studies21. Considering a higher intrinsic transmission led to similar conclusions. We did not consider immunity waning over time, but tested waned vaccine effectiveness. A large demand in tests results from reactively screening schools in high incidence conditions. Comparable resources could be more efficiently used in a proactive screening strategy to mitigate the peak.
