OBJECTIVE
Examine the effect of a universal facemask policy for healthcare workers (HCW) and incidence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) positivity.
METHODS
Daily number of symptomatic HCW tested, SARS-CoV-2 positivity rates, and HCW job-descriptions were collected pre and post Universal HCW facemask policy (March 26, 2020). Multiple change point regression was used to model positive-test-rate data. SARS-CoV-2 testing and positivity rates were compared for pre-intervention, transition, post-intervention, and follow-up periods.
RESULTS
Between March 12 and August 10, 2020, 19.2% of HCW were symptomatic for COVID-19 and underwent SARS-CoV-2 testing. A single change point was identified ∼March 28-30 (95% probability). Before the change point, the odds of a tested HCW having a positive result doubled every 4.5 to 7.5 days. Post-change-point, the odds of a tested HCW having a positive result halved every 10.5 to 13.5 days.
CONCLUSIONS
Universal facemasks were associated with reducing HCW's risk of acquiring COVID-19.
目的
研究医护人员（HCW）普遍佩戴口罩政策对严重急性呼吸综合征冠状病毒 2（SARS-CoV-2）阳性率的影响。
方法
收集普遍 HCW 口罩政策（2020 年 3 月 26 日）前后每日症状性 HCW 检测数量、SARS-CoV-2 阳性率和 HCW 工作描述。采用多变化点回归对阳性检测率数据进行建模。比较干预前、过渡期、干预后和随访期的 SARS-CoV-2 检测和阳性率。
结果
2020 年 3 月 12 日至 8 月 10 日期间，19.2%的 HCW 出现 COVID-19 症状并接受了 SARS-CoV-2 检测。确定了一个单一的变化点，大约在 3 月 28-30 日（95%概率）。在变化点之前，接受检测的 HCW 阳性结果的几率每 4.5 至 7.5 天增加一倍。变化点后，接受检测的 HCW 阳性结果的几率每 10.5 至 13.5 天减半。
结论
普遍佩戴口罩与降低 HCW 感染 COVID-19 的风险有关。
