Eight states were reported to have at least 75% mask adherence in any month between June and September (AZ, CT, HI, MA, NY, RI, VT, VA); none reported a high COVID-19 rate in the subsequent month. Rhode Island. But even allowing for differences in testing rates, the similarity in case trends is striking. | Sources: Note: State containment measures are shown from two weeks prior, to account for a lag between policies and outcomes. Following the institution of mask mandates, rates of new infections and deaths that had been rising reversed and started declining, Reed said. Variants of COVID-19 Are Spreading Across the U.S. How to Plan a COVID-Safe Summer Vacation in 2022. New Zealands prime minister, Jacinda Ardern, called it a validation of the countrys go hard, go early strategy, in which the country reacts rapidly to signs of community spread. The global pandemic of SARS-CoV-2 has overwhelmed health care systems, marked by peak numbers of hospital and intensive care unit admissions and deaths [1,2]. According to Werler, Arizonas data was unexpected. Nevertheless, it is possible that average mask adherence in a given month does not capture the most effective time period that influences COVID-19 rates. Eleven states had no stay-at-home order, 15 had no mask policy, and four states had low adherence throughout this six-month period. [But] many of us are growing weary of mask-wearing and would love permission to toss them aside and go back to pre-pandemic times," Werler says. In fact, it doesn't study mask efficacy at all. In Maryland , Gov. Costs vs. benefits of COVID-19 lockdowns and mask mandates revealed in new research Thu, 01/12/2023 LAWRENCE Beginning in 2020, most state governors ordered lockdowns and mask mandates to combat the COVID-19 pandemic. Methodology, States and D.C. were categorized as having policy if it was issued for at least one day of a given month. Privacy Policy | Mask wearing has been advocated by public health officials as a way to reduce the spread of COVID-19. Its a graph that should be required viewing for everyone still wearing a mask and every public official or journalist who still insists that mask mandates control the spread.. While it controlled for other policies that have been used to try to mitigate new infections from the coronavirus including bar closures, stay-at-home orders and bans on gatherings of 10 or more people it did not account for some others, such as physical distancing recommendations and other types of business closures. If you've seen pictures of those kids, you know they are not necessarily using masks as intended. https://doi.org/10.1371/journal.pone.0249891.g002. For mask policy and adherence in September in relation to high COVID-19 rates in October, collinearity caused the odds ratio to flip. Mask mandates are associated with reductions in COVID-19 case and hospitalization growth rates (6,7), whereas reopening on-premises dining at restaurants, a known risk factor associated with SARS-CoV-2 infection (2), is associated with increased COVID-19 cases and deaths, particularly in the absence of mask mandates (8). 18, 2020. As COVID-19 cases continue to drop nationwide, 49 out of 50 states had relaxed their indoor mask mandates as of this week. Now, nearly one in 10 North Dakotans have tested positive about a third of those in the past two weeks and one in 1,000 have died of the virus. When Youve Been Fully Vaccinated. Several other states have implemented or tightened. All the state does is encourage Alaskans to do their part to limit the spread of Covid-19, recommending that residents practice social distancing and wear a mask, without any mandate. A relationship between policies and the outbreaks severity has become more clear as the pandemic has progressed. Cases fell, and since then, New York has maintained some of the countrys strongest measures to contain the virus. Funding: The authors received no specific funding for this work. According to Werler, Arizona's data was unexpected. The United States, as of Friday, posted a seven-day moving average of 62,555 new COVID-19 cases reported daily, according to data from the Centers for Disease Control and Prevention.The last time . In the United States, policies on mask wearing have varied from state to state over the course of the pandemic. "Our results suggest that mask-wearing is strongly affected by factors other than mandates. 2.18.2022 4:30 PM. The mandates typically began early in the pandemic in 2020 and remained until at least the summer of 2021, with some extending into 2022. When the initial spring wave in 2020 subsided, public officials and journalists claimed that the mandates had worked, and they kept up the pretense even when Covid surged again later that year despite the continuing mandates. For the most recent updates on COVID-19, visit our coronavirus news page. Another consideration is that access to COVID-19 testing appears to vary from state to state [21]. California tested a larger share of its population at the peak of its omicron surge than Florida did, and Florida's positivity rate was higher, which suggests that Florida missed a larger share of infections than California. Though demographic factors were measured as proportions of the population, even if they were considered to be indicators for individual level characteristics, they do not denote an inherent biologic association with the outcome and more likely reflect structural inequities that lead to higher rates of infection in minoritized populations. States with stronger policy responses over the long run are seeing comparatively smaller outbreaks. Even Greenpeace now admits the obvious: recycling doesnt work. Of course, many other factors are could be at play, like the possibility of cooler weather driving non-adherent persons to indoor gatherings. Investigation, Mask wearing has been advocated by public health officials as a way to reduce the spread of COVID-19 [35]. Jacob Sullum The. Mean COVID-19 rates for states with at least 75% mask adherence in the preceding month was 109.26 per 100,000 compared to 249.99 per 100,000 for those with less adherence. For a while, the residents were spared. We infer that mandates likely did not affect COVID-19 case growth, as growth rates were similar on all days between actual or modeled issuance dates and 6 March 2021. For demographic data, we dichotomized population proportions at whole values that approximated the highest quartile of the distributions. Former Arizona AG Found No Evidence of 2020 Election Fraud. Conceptualization, Data on population distributions from the COVID-19 US State Policy Database [13] came from the US Census. Thats a huge swing, Werler says. One America News Network on March 7 published an article under the headline CDC: Face masks dont prevent COVID-19, study finds masks have negligible impact on coronavirus numbers. The post claims the CDC has admitted face masks do little to prevent the spread of COVID-19 amid mounting pressure to lift mask mandates across the U.S., Butthe CDCs study doesnt say that. Specifically, we created the following categories: >15% non-Hispanic Black, >15% Hispanic, median age >40 years, and population density >200 people per square mile, which corresponded to 74.5%, 78.4%, 82.4%, and 78.4% of the distributions, respectively. Outbreaks are comparatively smaller in states where efforts to contain the virus were stronger over the summer and fall potential good news for leaders taking action now. We classified a state and D.C. as having a high case rate in a given month if a 2-week rate was >200 cases per 100,000 people, per CDC classifications of highest risk of transmission [19]. Higher mask use (rather than mandates per se) has been argued to decrease COVID-19 growth rates. That second observation requires a caveat, since testing rates affect the number of cases that are recorded. For all 50 states and D.C., data on mask wearing and physical distance policies, mask adherence, COVID-19 cases, and demographics were abstracted from publicly available sources. Eleven states never mandated masks, while the other 39 states enforced mandates. The county in the spotlight right now is Los Angeles County, where cases have spiked over the past few weeks with more than 2,700 new COVID infections per day, which is a 180% increase since Nov. 1. Research suggests that mandatory mask-wearing policies correlated with a lower number of COVID-19 infections and deaths. John Tierney is a contributing editor of City Journal and coauthor of The Power of Bad: How the Negativity Effect Rules Us and How We Can Rule It. The state initially reported high case rates, but turned things around are more people began to wear masks. Brooks JT & Butler JC. Masks make no difference in reducing the spread of Covid, according to an extensive new review by Cochranethe gold standard for evaluating health interventions. The pandemic has eased, but not the compulsion of many Americans to cover their faces. Massachusetts. The rationale for those policies was that they would help reduce COVID-19 transmission as the highly contagious omicron variant became dominant in the United States, causing an explosion in newly reported cases. Among states and D.C. with no mask wearing policy, 50 to 73% had high COVID-19 rates in the subsequent month. "The states with mask mandates haven't fared significantly better than the 35 states that didn't impose them during the omicron wave. 3.1.2023 9:30 AM, Damon Root Over the course of the pandemic, the scientific evidence and our understanding of masks have grown. The study concluded that mask mandates and use are not associated with slower state-level Covid-19 spread during Covid-19 growth surges. The medias narrative about masks extended throughout the world.

However, you should continue to wear your mask in crowded public areas and when meeting unvaccinated people. Because high COVID rates were reported by only eight states in May and four states in June, we did not examine mask adherence or policy in the preceding April or May. In contrast, 25% or fewer states with a mask wearing policy had high COVID-19 rates, except in September when over half experienced high rates. The information in this article is current as of the date listed, which means newer information may be available when you read this. When Can I Go to the Movie Theater Again After Being Fully Vaccinated? Many local leaders went further. Data Availability: Data are available in the paper and its Supporting Information file. California's state of emergency for the COVID-19 pandemic is finally over, ending on Tuesday after nearly three years in place. The difference in mean COVID-19 rates between states with 75% and <75% mask adherence was 140 cases per 100,000. While mandates required shoppers to don masks before entering supermarkets, for example, the risk of transmission in such settings is low, given the amount of time customers usually spend in them, the size of the air space, and typically wide distances between patrons. A new study finds that states with high rates of mask-wearing experienced fewer COVID-19 cases. The graph for New York, which also had a statewide mask mandate, looks very much like the graph for California, but with an earlier peak. We observed some benefit of mask policy on COVID-19 rates, but the findings were unstable. The estimated absolute change in cumulative case rate associated with lifting the mask mandate, remains 28.1 (30.6%) 21 days after lifting the mask mandate. 3.1.2023 11:20 AM, Elizabeth Nolan Brown Prior to adopting mask mandates, those municipalities that eventually adopted mandates had higher transmission rates than the rest of the state, with the mean case rate difference per 100,000 people increasing by 0.32 cases per day (slope of difference = 0.32; 95% CI 0.13 to 0.51). Laboratory studies indicate that masks, especially N95 respirators, can help reduce virus transmission. How Are States Responding to CDC Mask Guidelines? The masks in Germany obviously didnt beat Covid. From the start of the pandemic through this spring, the cumulative rate of Covid mortality has been slightly higher in Sweden than in Germany (by about 15 percent), but the rate of overall excess mortality has been slightly higher in Germany (by about 8 percent). Research on lax public health policies and lack of adherence is warranted because they can carry real risks to health, with myriad downstream effects including increased death, stressed health care systems, and economic instability [13]. 2 minute read. Instead of carefully analyzing the effects of masks, the CDC repeatedly tried to justify them by misrepresenting short-term trends and hyping badly flawed research, like studies in Arizona and Kansas purporting to show that infections had been dramatically reduced by the mask mandates imposed in some counties. Writing original draft. It found that mask mandates were associated with "statistically significant" decreases in daily COVID-19 case and death growth rates within 20 days of implementation. The mandate will still require masks where . Our analysis of state and D.C.-level data does not account for variations in policy, adherence, and demographic factors at smaller geographic levels, such as county-levels. Yes Policy data on physical distancing were dichotomized as any versus no stay-at-home order during the April 1 to October 31, 2020 interval. This protective effect of mask wearing was evident across four months of the pandemic, even after adjusting the associations for mask policy, distance policy, and demographic factors. Methodology, | The pandemics second year saw slight deviations in both directions, but those reflected the seasonality of the virus and the geography of mask mandates, which remained more common in northern states. An Annals of Epidemiology study published last May found that mask mandates in the United States were associated with lower transmission rates from June through September 2020. The findings were published in the journal PLOS One in April. Many experts acknowledge that the rise and fall of waves is a bit of a mystery.". Although Hawaiis governor did not issue a mask wearing policy until after October 2020, we considered that state to have a policy because mayors of the four populous counties had mandated mask wearing earlier in the pandemic. "The probability of becoming a rapid riser county was 43% lower among counties that had statewide mask mandates at reopening," the researchers reported. The wave of new restrictions in the United States follows national and regional lockdowns in Europe, where outbreaks surged past their spring peaks but cases per capita remained lower than many Upper Midwest states. U.S. Centers for Disease Control and Prevention, March 5, ", U.S. Centers for Disease Control and Prevention, Nov. 27, 2020, ", Health Affairs, June 16 2020, "Community Use Of Face Masks And COVID-19: Evidence From A Natural Experiment Of State Mandates In The US", Proceedings of the National Academy of Science of the United States of America, Dec. 3, 2020, ", U.S. Centers for Disease Control and Prevention, Feb. 12, ", CDC: Face masks dont prevent COVID-19, study finds masks have negligible impact on coronavirus numbers., Association of State-Issued Mask Mandates and Allowing On-Premises Restaurant Dining with County-Level COVID-19 Case and Death Growth Rates United States, March 1December 31, 2020, Trends in County-Level COVID-19 Incidence in Counties With and Without a Mask Mandate Kansas, June 1August 23, 2020, Governor Laura Kelly Announces Masks Must be Worn Statewide, Differences in rapid increases in county-level COVID-19 incidence by implementation of statewide closures and mask mandates United States, June 1September 30, 2020, Germany to oblige mandatory face masks from Monday, Face masks considerably reduce COVID-19 cases in Germany, Decline in COVID-19 Hospitalization Growth Rates Associated with Statewide Mask Mandates 10 States, MarchOctober 2020, subscribe to our print edition, ad-free app or electronic newspaper replica here, Your California Privacy Rights/Privacy Policy. We divided the monthly number by 2.2 to obtain the number in a two-week period (43,088). States with more than 200 COVID-19 cases per 100,000 residents were considered to have a high case rate. Traveling This Summer? Yes The adoption of universal masking policies is increasingly polarized and politicized, demanding that public health authorities balance the values of health and individual liberty. All reviews and studies included in this document report on data collected in a time period prior This association between high mask adherence and reduced COVID-19 rates should influence policy makers and public health officials to focus on ways to improve mask adherence across the population in order to mitigate the spread of COVID-19. Coronavirus cases are rising in almost every U.S. state. The same study found that cloth masks did not have a statistically significant effect. The Power of Bad: How the Negativity Effect Rules Us and How We Can Rule It. The index comes from Oxfords Blavatnik School of Government, where researchers track the policies or lack thereof governments use to contain the virus and protect residents, such as contact tracing, mask mandates and restrictions on businesses and gatherings.
