Positive cell culture and PCR findings. Infectious isolates represent cultivated virus samples, while viral RNA represents all viruses, infectious and inactive. The thickness of the graph describes the relative number of SARS-CoV-2 positive samples on each day post infection (dpi). Individual positive samples are represented with dots on the graphs. Positive sample medians are illustrated with full lines and quartiles with dashed lines. Negative or weakly positive samplesare not shown in the graph, but they are presented with all other sample data in Supplement Table 1, and 2. On day four, 10 surfaces were sampled instead of four (Supplement Table 1, and 2). Graphs created with GraphPad Prism 10.2.1.
