在美国各国看到的较低的Covid-19速率，以更高的粘附佩戴

A new state-by-state analysis shows a statistical association between high adherence to mask wearing and reduced rates of COVID-19 in the U.S. Charlie Fischer and colleagues at the Boston University School of Public Health in Massachusetts present these findings in the open-access journal普罗斯一体4月14日。

在Covid-19大流行期间，不同的州已经在面具佩戴时颁布了不同的政策，其中一些州没有掩盖要求和其他要求面具在所有公共空间。了解面膜之间的联系和Covid-19税率可以帮助通知政策，以减轻对医疗保健系统的压力，经济不稳定和死亡。

To help clarify the effects of mask wearing, Fischer and colleagues examined publicly available data on mask-wearing policies, people's self-reported habits on mask wearing in public, and COVID-19 rates for all 50 U.S. states and Washington, D.C. They accounted for a one-month delay between mask wearing and its subsequent potential impact on COVID-19 rates from May through October 2020. For this analysis, they considered rates of more than 200 cases per 100,000 residents to be high.

分析表明，在15个状态下，不需要人们在公共场合佩戴面具，14个具有高Covid-19速率。与此同时，八个国家的自我报告的依从性率为75％，这些国家都没有高Covid-19率。依从性率最低的国家在随后的月份具有最高的Covid-19率的可能性。

在随后的月份，八个州的面罩穿着的面罩粘附的粘附性至少有109.26的平均Covid-19速率为每109.26个居民，而遵守持续75％的国家的平均Covid-19率为239.99。

这些调查结果提供了新的证据，以支持面膜穿着作为有助于减少Covid-19率的主要因素。他们建议减少Covid-19传播的政策和公共卫生努力应包括改进面具的重点坚持整个美国
