In the United States, policies on mask wearing have varied from state to state over the course of the pandemic [6]. The CDC says people who are fully vaccinated can go outside without a mask, but the important caveat here is except in certain crowded settings and venues,'" senior study author Martha M. Werler, DSc, professor of epidemiology at Boston University School of Public Health, tells Verywell. Cases were higher in the non-mandate states last summer, when the seasonal surge in the South disproportionately hit Republican states without mandates, but those states went on to have fewer cases during the winter, when the seasonal surge in the North hit more Democratic states with mandates. Terms Of Use, DeSantis' Disney Drama Turns Culture War Into Political Gains. The findings were published in the journal PLOS One in April. ", An August 2021 systematic review of 21 observational studies found that all of them "reported SARS-CoV-2 benefits" from mask mandates "in terms of reductions in either the incidence, hospitalization, or mortality, or a combination of these outcomes." 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. 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]. After briefly ramping up restrictions closing bars, restaurants, gyms, theaters and schools in March, when most other states did, Gov. For more information about PLOS Subject Areas, click Meantime, the medias favorite experts kept predicting doom for states that never mandated masks, like Florida, or that ended the mandates early in 2021, like Iowa, whose policy shift was denounced as reckless and delusional in a Washington Post article headlined, Welcome to Iowa, a state that doesnt care if you live or die. Iowas Covid death toll plummeted right after the article appeared. 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. Only eight states reported that 75% or more people wore masks between June and September, leading to fewer COVID cases: States with a 75% minimum mask adherence reported about 109.26 COVID-19 cases per 100,000 residents compared to the average of 249.99 per 100,000 residents in states with low mask adherence. 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. 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. 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. Of the 15 states with no mask policy from April through September, 14 reported high COVID-19 rates in at least one month from May to October. Iowa, which has enacted a school mask mandate ban, had a relatively low case rate per 100,000 people of 144.7.

Investigation, 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. Conceptualization, The CDC received some criticism for its junk science on masks, particularly for its false claims about the benefits of masking schoolchildren, but the press mostly promoted the agencys narrative. The information in this article is current as of the date listed, which means newer information may be available when you read this. Thats what this study was pursuing to try to answer,"said Michael Bisesi, vice dean and interim chair of environmental health sciences in Ohio State University's College of Public Health. Funding: The authors received no specific funding for this work. "Lifting of mask mandates across the board without consideration of the caveats does open the opportunity for another wave," Werler says. Should You Wear a Mask at Outdoor Events? For mask adherence levels, we utilized the Institute of Health Metrics and Evaluation (IHME) COVID-19 Projections online database [15], which holds data collected by Facebook Global in partnership with the University of Maryland Social Data Science Center [16].

No, Is the Subject Area "Public policy" applicable to this article? Germanys stringent policies have made it a consistent media darling. But as Flam notes, "the benefits of universal masking have been difficult to quantify" in the real world, where cloth models predominate and masks may not be clean, well-fitted, or worn properly. The black line on the graph shows the weekly rate of Covid cases in all the states with mask mandates that week, while the orange line shows the rate in all the states without mandates. The requirement is expected to be lifted on March 1. Vermont. States and D.C. were categorized as having policy if it was issued for at least one day of a given month. J.B. Pritzker. Randomized clinical trials involving flu viruses had shown, contrary to popular wisdom in Japan and other Asian countries, that there was no evidence that face masks are effective in reducing transmission, as the WHO summarized the scientific literature. Ron DeSantis issued an executive order May 3, 2021. that barred local governments and school systems from imposing COVID-19 restrictions, including mask rules. Theyre suffering from mask dependency, as this psychological affliction is termed in Japan, where a long tradition of mask-wearing during flu season has left some individuals afraid at any time to expose their faces in public. Charlie B. Fischer, Data on population distributions from the COVID-19 US State Policy Database [13] came from the US Census. 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. Writing original draft. And in New York and some other states, those lockdowns came too late to prevent a big outbreak, because thats where the virus hit first, said Thomas Hale, associate professor of global public policy at the Blavatnik School of Government, who leads the Oxford tracking effort. Over the course of the pandemic, the scientific evidence and our understanding of masks have grown. The pandemic has eased, but not the compulsion of many Americans to cover their faces. Further analyses of more granular geographic regions would be a logical next step. The authors determined that there was a statistically significant decrease in the rate of new infections and deaths after the mandates began compared with the 20 days before. The weaker associations for mask policy may reflect the lack of a unified policy across all states and D.C. and the inconsistent messaging by the media and government leaders. The Centers for Disease Control & Prevention (CDC) recently relaxed their COVID-19 guidelines, allowing fully vaccinated people to forego masks outside. We were not able to measure statistical interactions between mask policy and adherence due to instability arising from small numbers. Wearing a mask may still give some people a sense of security, but they could breathe more easily if theyd face the facts. A couple weeks into those lockdowns, countries with new restrictions may be seeing results: The rate of new daily cases has begun to level off or drop in France, Spain, Germany and Italy, though it continues to rise in the United Kingdom. If Florida's case numbers understate the true number of infections more than California's do, that could partially explain the difference in COVID-19 deaths per capita. Jha thinks vaccination rates areanother important factor: While "only 59% of eligible Florida seniors have gotten boosted," he notes, the rate for California is 70 percent. So did New Mexico, whose surge began shortly after Scientific American praised the states strict mask policies in an article headlined, How New Mexico Controlled the Spread of Covid-19.. If this is true, we would expect associations between mask adherence and high COVID-19 rates to be even stronger. One of the biggest problems in the United States so far has been the lack of a coherent, cohesive national response, said Wafaa El-Sadr, an epidemiologist at Columbia University. For policies on physical distancing, we recorded whether a stay-at-home order was issued and, if so, when. Crude and adjusted odds ratios for any mask policy in relation to high COVID-19 rates in the subsequent month were below 1.0; but confidence intervals were wide. here. According to Werler, Arizona's data was unexpected. 2.18.2022 4:30 PM. We examined the impact of state-based mask wearing policy and adherence on COVID-19 case rates during the summer and early fall of 2020 in order to quantify this effect. It is important to note that state level distributions of demographic factors do not account for concentrations or sparsity of populations within a given state. They continued to fall over the 100 days analyzed in the study. 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. Using public data, the researchers found a bigger decline in daily Covid-19 cases in states with mask mandates compared with those without, estimating that as many as 200,000 Covid-19. [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. Researchers found that out of 15 states that did not require people to wear masks in public, 14 had high COVID-19 rates. 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. We abstracted data on whether the state issued a mandate of mask use by all individuals in public spaces, and if so, the dates of implementation and whether the mandate was enforced by fines or criminal charge/citation(s). At the beginning of November, most states were scoring in the 40s and 50s. Yes But the surge is worst now in places where leaders neglected to keep up forceful virus containment efforts or failed to implement basic measures like mask mandates in the first place, according to a New York Times analysis of data from the University of Oxford. PLoS ONE 16(4): Sources: Restrictions tightened as cases were rising. Writing original draft, The resurgence was blamed on people disobeying the mandates, never mind the surveys showing widespread compliance. Theyre not looking at masks in and of themselves," Josh Petrie, research professor in the University of Michigan's School of Public Health, told USA TODAY. "Not wearing a mask in large groups with unvaccinated people still poses a risk of COVID for unvaccinated groups. More state leaders acted to strike down mask mandates on Thursday, citing a decline in COVID-19 cases and hospitalizations. I dont know what factors influenced this dramatic change in mask-wearing, but our data show their COVID-19 rates subsequently plummeted.. Effectiveness of Mask Wearing to Control Community Spread of SARS-CoV-2. The claim that a CDC study found face masks to have a negligible effect on the spread of COVID-19 is FALSE. 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. Both mask policy and mask adherence for states and D.C. were cross-tabulated with high case rates in the subsequent month. The study also found a statistically significant increase in the rate of COVID-19 infections and deaths starting 40 days after indoor or outdoor dining at restaurants was allowed. 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. But the study did not take into account other policies or voluntary safeguards that may have differed between jurisdictions with and without mask mandates. The study used county-level data from March 1 through Dec. 31 of last year, comparing data from before mandates tookeffect to the time period when they were in place.

To reduce the rate of COVID-19 cases nationwide, Werler says people need to wear their masks. Decreases in the rate of new infections and deaths from the virus were statistically significant, the studys authors found. 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. Over the course of the pandemic, both Iowa and Florida have done better than the national average in measures of Covid mortality as well as overall excess mortality (the number of deaths more than normal from all causes). Swedens initial Covid surge was blamed on those lax policies, but Sweden stuck to them and actually discouraged masks in most situations. In contrast, just one state in July, August, and September and three in October in the high quartile had high COVID-19 rates in the subsequent month. The opposite was true for states with mandates.

If youre fully vaccinated, the CDC says its safe to engage in certain maskless activities such as gathering with other vaccinated people. Maskaholics in the press are calling for permanent masking on trains, planes, and buses. Laboratory studies indicate that masks, especially N95 respirators, can help reduce virus transmission. Thus, policy and adherence levels in a given month were contrasted with lagged COVID-19 case rates in the subsequent month. Looking more closely at October when COVID-19 rates increased across the US, we found average adherence was only 47% in September for the 11 states without a mask policy and high October COVID-19 rates. No, Is the Subject Area "Health care policy" applicable to this article?
