Abstract

Objective: Throughout the COVID-19 pandemic, the effectiveness of face mask mandates was intensely debated. The objective of this study was to describe how face mask mandates at the state, county, and local levels differed in their effectiveness in reducing the number of COVID-19 cases in the jurisdiction where the mandate was implemented and throughout Utah.

Methods: We used publicly available data from the Utah Department of Health and Human Services. We calculated the effectiveness of face mask mandates (EFm) in each local health district after 3 key mandates: the enactment of face mask mandates in Salt Lake and Summit counties (SLSC) on June 28, 2020, and June 27, 2020, respectively; the enactment of a statewide face mask mandate on November 9, 2020; and the lifting of the statewide face mask mandate on April 10, 2021.

Results: Most counties in Utah had a reduction in the growth rate of COVID-19 cases after enactment of face mask mandates. We found an average 11.9% reduction in EFm after the introduction of the SLSC face mask mandates, with 8 of 13 local health districts experiencing a reduction, and an average 12.7% reduction after introduction of the statewide mandate, with 12 of 13 local health districts experiencing a reduction. After mandates were lifted, many counties had an increase in EFm.

Conclusion: Face mask mandates were an effective way to reduce transmission of COVID-19 in local jurisdictions and in neighboring jurisdictions in Utah. Our evidence supports the use of face mask mandates as a way to prevent disease transmission and be better equipped to respond to future pandemics.

在犹他州强制使用口罩对 COVID-19 传播的效果。
目的:在 COVID-19 大流行期间,人们对口罩强制措施的有效性进行了激烈的讨论。本研究旨在描述州、县和地方各级口罩强制措施在减少强制措施实施辖区和整个犹他州 COVID-19 病例数量方面的效果有何不同:我们使用了犹他州卫生与公众服务部公开提供的数据。我们计算了 3 项关键任务后每个地方卫生区的口罩任务有效性(EFm):盐湖郡和高峰郡(SLSC)分别于 2020 年 6 月 28 日和 2020 年 6 月 27 日颁布口罩任务;2020 年 11 月 9 日颁布全州口罩任务;2021 年 4 月 10 日取消全州口罩任务:结果:犹他州大多数县在颁布口罩规定后,COVID-19病例的增长率都有所下降。我们发现,在引入 SLSC 口罩强制规定后,EFm 平均下降了 11.9%,13 个地方卫生区中有 8 个出现下降;在引入全州强制规定后,EFm 平均下降了 12.7%,13 个地方卫生区中有 12 个出现下降。任务取消后,许多县的 EFm 有所上升:在犹他州的地方辖区和邻近辖区,口罩强制措施是减少 COVID-19 传播的有效方法。我们的证据支持使用口罩强制措施来预防疾病传播,并更好地应对未来的流行病。

期刊介绍: Public Health Reports is the official journal of the Office of the U.S. Surgeon General and the U.S. Public Health Service and has been published since 1878. It is published bimonthly, plus supplement issues, through an official agreement with the Association of Schools and Programs of Public Health. The journal is peer-reviewed and publishes original research and commentaries in the areas of public health practice and methodology, original research, public health law, and public health schools and teaching. Issues contain regular commentaries by the U.S. Surgeon General and executives of the U.S. Department of Health and Human Services and the Office of the Assistant Secretary of Health. The journal focuses upon such topics as tobacco control, teenage violence, occupational disease and injury, immunization, drug policy, lead screening, health disparities, and many other key and emerging public health issues. In addition to the six regular issues, PHR produces supplemental issues approximately 2-5 times per year which focus on specific topics that are of particular interest to our readership. The journal''s contributors are on the front line of public health and they present their work in a readable and accessible format.
