A-E Key dates of the Austrian social distancing policy (A), the Austrian POC-LFT policy (B), and heatmaps of COVID-19 PCR positivity during the study period (C-D). A: Timeline of the different national social distancing policy restrictions during the first wave and the beginning of the second wave, and details of the Austrian symptomatic point-of-care lateral flow antigen tests (POC-LFT) policy introduced as of October 22, 2020. B: Description of the clinical pathway recommended by the Austrian COVID-19 testing policy, including the possible outcomes of SARS-CoV2 infection during the study period. C-E: Heatmaps of the PCR positive cases before (C), during (D) and after (E) the second COVID-19 wave between October 22 and December 06, 2020, across the 94 Austrian districts studied. The geographical maps (C-E) were generated using the free Tableau Public software (https://public.tableau.com/en-us/s/); districts with high POC-LFT use are labelled in blue and shaded according to their activity, and districts with low activity are shaded in red. For clarity, districts with medium activity (grey) were not shaded. POC-LFT: point-of-care lateral flow antigen test.
