Preprint describing the first results (round 1 & 2) from the Austrian School-SARS-CoV-2 study available

The Austrian School-SARS-CoV-2 consortium (scientifically coordinated by Michael Wagner) has assembled a manuscript describing the first results from the "gargling study" in almost 250 Austrian schools. In total almost 14.000 tests were performed to determine the prevalence of SARS-CoV-2 among pupils and teachers in September/October and November 2020 and to identify factors that correlate with increased prevalences.
