In 2020-2021, a Colorado corrections facility experienced four COVID-19 outbreaks. Case counts, attack rates (ARs) in people who are detained or incarcerated (PDI), and mitigation measures used in each outbreak were compared to evaluate effects of combined strategies. Serial PCR testing, isolation/quarantine, and masking were implemented in outbreak 1. Daily staff antigen testing began in outbreak 2. Facility-wide COVID-19 vaccination started in outbreak 3 and coverage increased by the end of outbreak 4 (PDI: <1% to 59%, staff: 27% to 40%). Despite detection of variants of concern, outbreaks 3 and 4 had 97% lower PDI ARs (both 1%) than outbreak 2 (29%). Daily staff testing and increasing vaccination coverage, with other outbreak mitigation strategies, are important to reduce COVID-19 transmission in congregate settings.

使用包括疫苗接种在内的分层缓解策略评估惩教设施 COVID-19 爆发：科罗拉多州，2020-2021 年。

2020-2021 年，科罗拉多州的一个惩教机构爆发了四次 COVID-19 疫情。比较了每次爆发时使用的病例数、被拘留或监禁者 (PDI) 的发病率 (AR) 和缓解措施，以评估联合策略的效果。在疫情 1 中实施了系列 PCR 检测、隔离/检疫和掩蔽。在疫情 2 中开始进行日常工作人员抗原检测。在疫情 3 中开始在设施范围内接种 COVID-19，在疫情 4 结束时覆盖率有所增加（PDI：<1 % 至 59%，员工：27% 至 40%）。尽管检测到令人担忧的变体，但与爆发 2 (29%) 相比，爆发 3 和 4 的 PDI ARs（均为 1%）低 97%。日常工作人员检测和增加疫苗接种覆盖率，以及其他缓解疫情的策略，对于减少 COVID-19 在人群聚集环境中的传播非常重要。
