OBJECTIVE
To analyze workplace outbreaks by industry sector in the first wave of the pandemic, and associated household cases.
METHODS
Number, size, and duration of outbreaks were described by sector, and outbreak cases were compared to sporadic cases in the same time frame. Address matching identified household cases with onset ≥2 days before, ≥2 days after, or within 1 day of the workplace outbreak case.
RESULTS
There were 199 outbreaks with 1245 cases, and 68% of outbreaks and 80% of cases belonged to (1) Manufacturing, (2) Agriculture, Forestry, Fishing, Hunting, (3) Transportation and Warehousing. There were 608 household cases associated with 339 (31%) outbreak cases, increasing the burden of illness by 56%.
CONCLUSIONS
Workplace outbreaks primarily occurred in three sectors. Prevention measures should target industry sectors at risk to prevent spread in and out of the workplace.

方法
按行业描述暴发的数量、规模和持续时间，并将暴发病例与同一时期的散发病例进行比较。地址匹配确定了家庭病例的发病日期，发病日期在工作场所暴发病例前≥2 天、≥2 天或 1 天内。
结果
共有 199 次暴发，涉及 1245 例病例，其中 68%的暴发和 80%的病例属于（1）制造业，（2）农业、林业、渔业、狩猎、（3）运输和仓储。有 608 例家庭病例与 339 例（31%）暴发病例有关，使疾病负担增加了 56%。
结论
工作场所暴发主要发生在三个行业。预防措施应针对有风险的行业部门，以防止工作场所内外的传播。
