Comparison of occupation type over time. (A) Count of all patients based on occupation type. Healthcare worker (HCW) predominance in the beginning months of the pandemic versus non-HCW in the final months of the data gathering. HCW-D = HCW with direct patient contact, HCW-A = HCW with indirect contact. The time of each public intervention is shown in parallel; lockdown was between March 23rd and May 30th 2020, start of vaccination of HCWs was in January 2021, and start of vaccination of non-HCWs was in April 2021. Face mask use was mandated for public with the start of lockdown. (B) Percent HCW (both direct and indirect) in all positive patients declined rapidly (tau=−0.52, p<0.0001) in the first months of the pandemic, then it stays relatively steady over the rest of the data gathering (blue line and dots, tau =+0.10, p=0.62).
