In Atlantic Canada and Canada’s territories most SARS-CoV-2 cases were importations and close contacts of these travellers from July 1, 2020 to May 31, 2021. Panels A–F show imported cases (dark shading, solid line), their close contacts (medium shading, dashed line), and community cases (light shading, no line) with the vertical axis limit as 20% more than the maximum number of reported weekly travel-related cases so that brief periods of large community outbreaks do not dominate the graphs. From July 1, 2020–May 31, 2021, panels G–H show the percentage of reported daily cases that were travel-related (dots; also shown as a shaded density plot, G), and the total number of imported cases and their close contacts (H).
