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.
We used publicly available data from the Utah Department of Health and Human Services. We calculated the effectiveness of face mask mandates () 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.
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 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 .
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.
在整个新冠疫情期间，口罩强制令的有效性引发了激烈辩论。本研究的目的是描述州、县和地方各级的口罩强制令在其实施辖区及整个犹他州减少新冠病例数量方面的有效性有何不同。
我们使用了犹他州卫生与公众服务部公开的数据。我们计算了三项关键强制令实施后每个地方卫生区口罩强制令的有效性（）：盐湖县和峰会县分别于2020年6月28日和2020年6月27日颁布口罩强制令；2020年11月9日颁布全州范围的口罩强制令；以及2021年4月10日解除全州范围的口罩强制令。
犹他州的大多数县在颁布口罩强制令后新冠病例增长率有所下降。我们发现，盐湖县和峰会县颁布口罩强制令后，平均下降了11.9%，13个地方卫生区中有8个出现下降；全州范围的强制令颁布后，平均下降了12.7%，13个地方卫生区中有12个出现下降。强制令解除后，许多县的有所上升。
口罩强制令是减少犹他州地方辖区及邻近辖区新冠病毒传播的有效方式。我们的证据支持使用口罩强制令作为预防疾病传播的一种方式，并更好地应对未来的疫情。
