Figure 1

Timeline of events identified during the epidemiologic investigation of an outbreak of SARS-CoV-2 infection among Malayan tigers and humans at a zoo, Tennessee, USA, October 12–30, 2020. Dates related to tiger events are shown above the timeline; dates related to human events are shown below the timeline. Ct values for the first positive open reading frame 1b reverse transcription PCR test per animal are shown; methods for extraction and Ct value calculation were described previously by Sawatzki et al. (11). Ct, cycle threshold; SARS-CoV-2, severe acute respiratory syndrome coronavirus 2.
