Background Work-related exposures play an important role in SARS-CoV-2 transmission, yet few studies have measured the risk of COVID-19 across occupations and industries. Methods During September 2020 – May 2021, the Wisconsin Department of Health Services collected occupation and industry data as part of routine COVID-19 case investigations. Adults aged 18-64 years with confirmed or probable COVID-19 in Wisconsin were assigned standardized occupation and industry codes. Cumulative incidence rates were weighted for non-response and calculated using full-time equivalent (FTE) workforce denominators from the 2020 American Community Survey. Results An estimated 11.6% of workers (347,013 of 2.98 million) in Wisconsin, ages 18-64 years, had COVID-19 from September 2020 to May 2021. The highest incidence by occupation (per 100 full-time equivalents) occurred among personal care and services workers (22.4), healthcare practitioners and support staff (20.7), and protective services workers (20.7). High risk sub-groups included nursing assistants and personal care aides (28.8), childcare workers (25.8), food and beverage service workers (25.3), personal appearance workers (24.4), and law enforcement workers (24.1). By industry, incidence was highest in healthcare (18.6); the highest risk sub-sectors were nursing care facilities (30.5) and warehousing (28.5). Conclusions This analysis represents one of the most complete examinations to date of COVID-19 incidence by occupation and industry. Our approach demonstrates the value of standardized occupational data collection by public health, and may be a model for improved occupational surveillance elsewhere. Workers at higher risk of SARS-CoV-2 exposure may benefit from targeted workplace COVID-19 vaccination and mitigation efforts.

衡量 COVID-19 的工作相关风险：按职业和行业划分的 COVID-19 发病率比较——威斯康星州，2020 年 9 月至 2021 年 5 月

背景 与工作相关的接触在 SARS-CoV-2 传播中起着重要作用，但很少有研究衡量 COVID-19 在不同职业和行业中的风险。方法 在 2020 年 9 月至 2021 年 5 月期间，威斯康星州卫生服务部收集了职业和行业数据，作为常规 COVID-19 病例调查的一部分。威斯康星州 18-64 岁确诊或可能感染 COVID-19 的成年人被分配了标准化的职业和行业代码。累积发生率针对未答复进行加权，并使用 2020 年美国社区调查中的全职当量 (FTE) 劳动力分母进行计算。结果 据估计，从 2020 年 9 月到 2021 年 5 月，威斯康星州 18-64 岁的工人中有 11.6%（298 万人中的 347,013 人）感染了 COVID-19。按职业（每 100 个全职当量）发生率最高的是个人护理和服务人员 (22.4)、医疗保健从业人员和支持人员 (20.7) 以及保护服务人员 (20.7)。高风险子群体包括护理助理和个人护理助理 (28.8)、儿童保育人员 (25.8)、餐饮服务人员 (25.3)、仪容工作人员 (24.4) 和执法人员 (24.1)。按行业划分，医疗保健行业的发病率最高 (18.6)；风险最高的子行业是护理设施 (30.5) 和仓储 (28.5)。结论 该分析代表了迄今为止按职业和行业对 COVID-19 发病率进行的最完整的检查之一。我们的方法证明了公共卫生标准化职业数据收集的价值，并可能成为其他地方改进职业监督的典范。接触 SARS-CoV-2 风险较高的工人可能会受益于有针对性的工作场所 COVID-19 疫苗接种和缓解措施。
