↵* The following shelters and dates were included in the analysis: Shelter A (Apr. 23); Shelter A (May 6); Shelter A (May 8); Shelter E (May 21); Shelter A (May 26); Shelter F (May 28); Shelter F (June 1); Shelter H (June 11). Detailed demographic information was collected for 44 residents who tested positive for SARS-CoV-2 and 198 residents who tested negative for SARS-CoV-2, including race (n = 42 and n = 198, respectively), past medical history (n = 36 and n = 173, respectively), symptoms (n = 44 and n = 198, respectively) and whether the individual visited another shelter (n = 44 and n = 198, respectively).
