Figure 2

Examples of probable and possible chains of transmission during SARS-CoV-2 outbreak in maximum-security prison in Australia, 2021. Cases are plotted temporally on the basis of infection date and spatially according to both location of infection acquisition and location at the time of diagnosis. Diamonds denote incarcerated persons working as sweepers and circles indicate community-acquired cases. Transmission is visualized with solid lines for probable transmission, dotted lines for possible, and double solid black lines for transmission between cellmates consistently housed together before and after lockdown. Arrowheads mark the likely direction of transmission, and line colors represent genomic sequence clusters. For transmission pathways where only 1 genomic sequence was available, the sequence identification is displayed below the patient.
