• Description:
  Background.
  
  Work is a social determinant of health that is often overlooked. There are major work-related differences in the risk of SARS-CoV-2 infection and death, but there have been few analyses of infection rates across industry groups. To date, only one national assessment of SARS-CoV-2 infection prevalence by industry based on self-report has been completed. No study has looked at seroprevalence of COVID-19 by industry.
  
  Methods.
  
  During May–December 2021, blood donors with SARS-CoV-2 anti-nucleocapsid testing were sent an electronic survey about their work. Free-text industry responses were classified using the North American Industry Classification System. We estimated seroprevalence and 95% confidence intervals (CIs) of SARS-CoV-2 infection by industry.
  
  Results.
  
  Of 57,726 donors, 7,040 (12%, 95% CI: 11.9%, 12.5%) had prior SARS-CoV-2 infection. Seroprevalence was highest among Accommodation & Food Services (19.3%, 95% CI: 17.1%, 21.6%), Mining, Quarrying, and Oil and Gas Extraction (19.2%, 95% CI: 12.8%, 27.8%), Healthcare & Social Assistance (15.6%, 95% CI: 14.9%, 16.4%), and Construction (14.7%, 95% CI: 13.1%, 16.3%). Seroprevalence was lowest among Management of Companies & Enterprises (6.5%, 95% CI: 3.5%, 11.5%), Professional Scientific & Technical Services (8.4%, 95% CI: 7.7%, 9.0%), and Information (9.9%, 95% CI: 8.5%, 11.5%).
  
  Conclusions.
  
  While workers in all industries had serologic evidence of SARS-CoV-2 infection, certain sectors were disproportionately impacted. Disease surveillance systems should routinely collect work characteristics so public health and industry leaders can address health disparities using sector-specific policies.
