Non-specific psychological distress was measured using the Kessler Psychological Distress Scale (K10). Blood sample was collected using the dried blood spot (DBS) test for the detection (presence/absence) of IgG antibodies to SARS-CoV-2. Community-level information (e.g., rates of infection, outbreak level), was collected through published information from Public Health Ontario and Statistics Canada (for population data).
