Monthly COVID-19 case rates (number of cases per capita over two weeks) >200 per 100,000 residents were considered high. broad scope, and wide readership a perfect fit for your research every time. Fully vaccinated people should continue following CDC guidelines, including wearing their masks in crowded areas and when around unvaccinated people. 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. One state is the lone holdout. 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. It also examined the link between allowing on-site restaurant dining and the number of coronavirus cases and deaths. But since people were allowed to remove their masks while eating and drinking, requiring them to cover their faces upon entry was more a symbolic gesture than a serious safeguard. 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. Copyright When Can I Go to the Movie Theater Again After Being Fully Vaccinated? Eleven states never mandated masks, while the other 39 states enforced mandates. PLoS ONE 16(4): 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. 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 same study found that cloth masks did not have a statistically significant effect.

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. The mandate will still require masks where . "Masks have been the most visible part of America's pandemic response, but one of the least consequential," science journalist Faye Flam writes in a Bloomberg Opinion essay. "Our results suggest that mask-wearing is strongly affected by factors other than mandates. Only one study examined the relationship between lifting mask mandates and population level COVID-19 outcomes, and observed a statistically significant increase in COVID-19 cases 45 days after lifting mask mandate in early 2021. 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). Thus, adherence to mask wearing in public remains a challenge for mitigating the spread of COVID-19. "We do not find evidence that mandating mask-wearing reduces transmission," the authors reported. All reviews and studies included in this document report on data collected in a time period prior https://doi.org/10.1371/journal.pone.0249891.s001. Cases dropped in late July, but since then Texas has eased efforts to contain the virus, and cases are rising again. Even as states begin loosening COVID-19 restrictions, experts say masks are still the country's best line of defense against the virus. Just as in the United States, the mask mandates in Germany produced no net benefits but plenty of inconvenience as well as outright harm. Ron DeSantis issued an executive order May 3, 2021. that barred local governments and school systems from imposing COVID-19 restrictions, including mask rules. The same basic pattern was seen in nearly every state. COVID-19 death rates dropped by 0.7 percentage points in the first 20 days after masks were required. 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. Odds ratios indicating protection against high COVID-19 rates remained for all months and policy subgroups, ranging from 0.82 to 0.93 for states with any policy and from 0.60 to 0.95 for states with no policy. 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. They continued to fall over the 100 days analyzed in the study. 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). "The states with mask mandates haven't fared significantly better than the 35 states that didn't impose them during the omicron wave. 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. Here's what it could mean for all of us. Note: Measurements of government response come from the Oxford Covid-19 Government Response Trackers Containment and Health Index, which is the organizations index focused on virus containment and protecting citizen health. When Can I Travel Again After Being Fully Vaccinated? The current surge is worst in places with few containment measures. But as Miller shows in his book, the policies made no discernible difference. We combined the Recommended and Strict groups into Any policy. 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]. Note: Cases and hospitalizations are data from Nov. 16. We show supporting evidence for reducing the spread of COVID-19 through mask wearing. Conceptualization, Meanwhile, the eight states that reported 75% or more mask adherence between June 2020 and September 2020 did not have high COVID-19 rates. Methodology, + Caption. Fourteen of the 15 states with no mask wearing policy for the general public through September reported a high COVID-19 rate. On November 8, Utah implemented a mask mandate, as new daily Covid-19 cases continue to rise in the state and across the country. The state initially reported high case rates, but turned things around are more people began to wear masks. Researchers aggregate those indicators and assign a number from 0 to 100 to each governments total response. 3.1.2023 11:20 AM, Elizabeth Nolan Brown Czech Republic Has Lifesaving COVID-19 Lesson for America: Wear a Face Mask, USA Today announced early in the pandemic, but since then the Czech death toll has been one of the worlds highest. I just dont know based on reading the OAN summary how they came to the same conclusions because the CDC conclusions were favorable.. Because there are so many variables to account for, it is very difficult to isolate the impact of any given policy. We observed some benefit of mask policy on COVID-19 rates, but the findings were unstable. They looked at data from April to October 2020. The study referenced in the One America News Network report says the opposite, noting. Indeed, associations between mask policy, adherence and other factors may be obscured in states with many high density and low density areas. Yes "Nearly a year after California Gov. Data Availability: Data are available in the paper and its Supporting Information file. The claim that a CDC study found face masks to have a negligible effect on the spread of COVID-19 is FALSE. For a while, the residents were spared. Centers for Disease Control and Prevention. Brooks JT & Butler JC. States with mask mandates saw higher mask adherence. Parents have pushed for the mask mandate to be lifted for a number of reasons. When the outbreak slammed the New York City area in March and April, leaders locked down. It is also possible that survey respondents misreported their mask wearing adherence; whether they would be more or less likely to over or under-report is open to speculation, but residents in states with mask wearing policy might over-report adherence to appear compliant. Jacob Sullum Eleanor J. Murray and Jennifer Weuve and the Boston University School of Public Health Epidemiology COVID-19 Response Corps for bringing together students and faculty for this project. Containment measures are as of Nov. 1. Jocelyn Solis-Moreira is a journalist specializing in health and science news. 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. Over the course of the pandemic, the scientific evidence and our understanding of masks have grown. Further analyses of more granular geographic regions would be a logical next step. Five states are rolling back mask mandates. Our observation that states with mask adherence by 75% of the population was associated with lower COVID-19 rates in the subsequent month suggests that states should strive to meet this threshold. Texas locked down in the spring, when it had relatively few cases, then reopened quickly. Clearly you dont want to wait too long because thats the mistake we made last time, when things spun out of control. Using an index that tracks policy responses to the pandemic, these charts show the number of new virus cases and hospitalizations in each state relative to the states recent containment measures. Decreases in the rate of new infections and deaths from the virus were statistically significant, the studys authors found. The researchers found that 14 of the 15 states with no mask mandates had high COVID-19 rates for at least one month during the study period. 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. Laboratory studies indicate that masks, especially N95 respirators, can help reduce virus transmission. Based on data from various countries and U.S. states from May to September 2020, a preprint study published last June found that general mask wearing was associated with a reduction in virus. The claim that a CDC study found face masks to have a negligible effect on the spread of COVID-19 is FALSE. Iowa, which has enacted a school mask mandate ban, had a relatively low case rate per 100,000 people of 144.7. But in each state, as Miller shows, infection rates remained lower in the counties that did not mandate masks. Mandating masks gave the illusion of doing something against the virus. Though many have taken fresh steps to contain the virus since then, the Times analysis compares cases and hospitalizations for a given date to a states index score from two weeks before, since researchers say it is reasonable to expect a lag between a policy's implementation and its outcome. | Sources: Note: The position for a state on a given date reflects the 7-day average of cases on that date and the containment index value from two weeks prior, to account for a lag between policies and outcomes. | Our analysis suggests high adherence to mask wearing could be a key factor in reducing the spread of COVID-19. In contrast, average adherence was 68% in the 15 states with lower COVID-19 rates in October and any mask policy in September. For all 50 states and the District of Columbia (DC), these data were abstracted by month for April September 2020 to measure their impact on COVID-19 rates in the subsequent month (May October 2020). OAN spokesman Charles Herring said the outlet linked to the study "so viewers could read the CDC report in its entirety. If this hasnt persuaded you to take off your mask, you can find lots more reasons in a book by Ian Miller, the data analyst who created the graph for City Journal. "Arizona surprised me because they went from having the second-lowest mask adherence in May and June [less than 22%] to the highest level in July and August [greater than 80%]. 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 list of states with high COVID-19 rates by month shows the initial wave in northeastern states in May, followed by a wave in southern states, and then spreading across the U.S. over the next four months (Table 2). | | Gavin Newsom ordered the nation's first statewide shutdown because of the coronavirus, masks remain mandated, indoor dining and other activities are significantly limited, and Disneyland remains closed. 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. Most states in the low quartile had high COVID-19 rates in the subsequent month. PLOS ONE promises fair, rigorous peer review, Looking at one state at a time, its possible to track the relationship between coronavirus policy and public health. Like the debate about lockdowns, the debate about mask mandates will continue. The surgical masks didnt stop a subsequent surge throughout the country, and infection rates in Bavaria and Berlin were the same as in German states without the N95 requirement. At Humble ISD, 4.59 percent have tested positive for COVID. https://doi.org/10.1371/journal.pone.0249891.g001. 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. Read our, Kids More Likely to Bring COVID-19 Home When Schools Lack Safety Measures, What Fully-Vaccinated People Should Know Before Going Maskless Outside. "Its that simple.. On the other hand, Hawaii and Connecticut had two of the longest mask mandates and also some of the lowest per capita case counts of all the states. High COVID-rates were less frequent in states and D.C. with strict mask wearing policy than in states with recommended policy. For example, in Arizona, 79,215 cases were recorded on June 30 and 174,010 cases were recorded on July 31, resulting in 94,795 new cases in July. Because stay-at-home order, mask wearing policy, mask adherence, and COVID-19 rates can vary from month to month, we listed those states with consistent classifications across the period April through September (or May through October for COVID-19 rates). Since July 27, 2020, individuals had been required to wear a mask or face covering in the state when visiting public indoor spaces and when unable to maintain a 6-foot distance from. It compares Germany with Sweden, the medias Covid villain for refusing to lock down or mandate masks. In Germany, by contrast, more than 80 percent did so, but look at the similar trajectories of the daily Covid death toll in both countries from the summer of 2020 through March of this year. Conceptualization, The lag between mask adherence measures and COVID-19 rates should reduce the chance of reverse causation, but high COVID-19 rates early in a month could affect mask adherence levels later in that month. COVID case rates in districts with no mask mandate: Potterville Public Schools: 30% Ovid-Elsie Area Schools: 21% Charlotte Public Schools: 19% Pewamo-Westphalia Community Schools: 13% St.. 3.1.2023 9:15 AM, Joe Lancaster If you add up all the numbers on those two lines, you find that the mask mandates made zero difference. Thailand, Japan, Taiwan, Hong Kong, the Philippines, Uruguay, Chile, Poland, and Hungary were all hailed as models of scientific enlightenment for their low infection rates and strict mask policiesuntil, as usual, the masks suddenly lost their magical power. For more information about PLOS Subject Areas, click These results were suggestive of an effect with a permutation-based P -value of 0.094. It is worth noting that no states achieved this level of mask adherence in September, which might account in part for the spike in COVID-19 rates in October. Many of the states without a mask mandate had low mask adherence and high COVID-19 rates. The Power of Bad: How the Negativity Effect Rules Us and How We Can Rule It. "Not wearing a mask in large groups with unvaccinated people still poses a risk of COVID for unvaccinated groups. Masks prevent you from inhaling or exhaling viral droplets that can linger in the air. Similar reductions in odds of high COVID-19 rates in August and September were observed for July and August mask adherence, respectively. Data curation, 2023 Manhattan Institute for Policy Research, Inc. All rights reserved. Despite an early outbreak, South Korea flattened the curve with aggressive testing and contact tracing, as well as widespread mask wearing. For now, relaxing some mask guidelines while staying vigilant is the government's compromise. In August 2020, the Congressional Research Service also wrote that federal constitutional precedents made it unlikely that the federal government could issue a national mask wearing mandate that applies to the 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). 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. Sources: Restrictions tightened as cases were rising. A relationship between policies and the outbreaks severity has become more clear as the pandemic has progressed. Covering up may give the maskaholics a false sense of securitybut they could breathe more easily if theyd just face the facts. Verywell Health's content is for informational and educational purposes only. 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. The pandemic has eased, but not the compulsion of many Americans to cover their faces. We calculated the average mask use percentage by month for AprilSeptember, 2020. Start the day smarter Notable deaths in 2023 The world's largest war . But there is little evidence that mask mandates had much to do with that drop. The requirement is expected to be lifted on March 1. 3.1.2023 2:50 PM, David McGarry Mr. Hale said the Oxford data makes it clear that acting quickly and forcefully is the best shot governments have to combat the virus. 3.1.2023 9:30 AM, Damon Root For demographic data, we dichotomized population proportions at whole values that approximated the highest quartile of the distributions. The graph tracks the results of a natural experiment that occurred nationwide during the pandemic. States that have kept more control policies in a more consistent way New England states, for example have avoided a summer surge and are now having a smaller fall surge, as opposed to states that rolled them back very quickly like Florida or Texas, Mr. Hale said. Masks make no difference in reducing the spread of Covid, according to an extensive new review by Cochranethe gold standard for evaluating health interventions. But the study did not take into account other policies or voluntary safeguards that may have differed between jurisdictions with and without mask mandates. States with the lowest levels of mask adherence were most likely to have high COVID-19 rates in the subsequent month, independent of mask policy or demographic factors. In fact, it doesn't study mask efficacy at all. Wearing masks is a CDC-recommended* approach to reduce the spread of SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), by reducing the spread of respiratory droplets into the air when a person coughs, sneezes, or talks and by reducing the inhalation of these droplets by the wearer. She finds that mask-wearing is still the best course of action for mixed-vaccination status gatherings. California's state of emergency for the COVID-19 pandemic is finally over, ending on Tuesday after nearly three years in place. Experts interviewed by USA TODAY said the One America News Network had "misinterpreted" or "mischaracterized" the findings of the CDC study. Discover a faster, simpler path to publishing in a high-quality journal. The States and Mask Mandates. In their pre-Covid planning strategies for a pandemic, neither the Centers for Disease Control nor the World Health Organization had recommended masking the publicfor good reason. https://doi.org/10.1371/journal.pone.0249891, Editor: Wen-Jun Tu, Chinese Academy of Medical Sciences and Peking Union Medical College, CHINA, Received: January 12, 2021; Accepted: March 26, 2021; Published: April 14, 2021. States and D.C. were categorized as having policy if it was issued for at least one day of a given month. Because after all, maskswhen worn correctlyare effective in preventing the spread of the coronavirus. Latest news. More could be on the way. Herring dismissed those results, claiming unnamed experts told the news network that the reductions in spread the study found were not significant. Of course, many other factors are could be at play, like the possibility of cooler weather driving non-adherent persons to indoor gatherings. Coronavirus: How R-0 can be used to fight COVID-19. States and cities are reinstating restrictions and implementing new ones: In recent days, the governors of Iowa, North Dakota and Utah imposed mask mandates for the first time since the outbreak began. 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]. "They dont know how well people complied with these mandates or what proportion of the populationwas actually wearing masks.. He Kept Quiet. 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. Daniella Amato is a biomedical scientist and fact checker with expertise in pharmaceuticals and clinical research. Some states now have ended their statewide masks mandates, but the president, and others, have urged them to reinstate masks mandates because of the recent upsurge that our nation has seen in COVID-19 cases. Instead, it links mask mandates to statistically significant decreases in county-level daily COVID-19 case and death growth rates within 20 days of implementation.. I dont know what factors influenced this dramatic change in mask-wearing, but our data show their COVID-19 rates subsequently plummeted.. Even as more and more states encourage or even mandate mask wearing, many citizens sti When Can I Dine Indoors Again After Being Fully Vaccinated? Many experts acknowledge that the rise and fall of waves is a bit of a mystery.". JAMA. The book documents how mask mandates were implemented without scientific justification, how they failed around the world, and how public officials and journalists have kept making fools of themselves by pretending otherwise. Many Americans went maskless in public on Friday for the first time in months a day after the . But a new study examines how the value of these actions also came with costs. We show that mask mandates are associated with a statistically significant decrease in new cases (-3.55 per 100K), deaths (-0.13 per 100K), and the proportion of hospital admissions (-2.38 percentage points) up to 40 days after the introduction of mask mandates both at the state and county level. Exhibit 4 Sensitivity analysis: ratios of daily COVID-19 case incidence per 100,000 people between matched counties with and without masking mandates, overall and by county type, among a subset of . But the "reference period" is defined by the report as the 20 days before mask mandates started. Explaining the justification for lifting mask requirements, governors and public health agencies generally have cited the precipitous decline in daily new cases since mid-January. We thank Drs. 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. 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. We recommend renewed efforts be employed to improve adherence to mask wearing. Coronavirus cases are rising in almost every U.S. state. 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. Click through the PLOS taxonomy to find articles in your field. 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. Here's What's Safe and What You Should Avoid, How To Plan a COVID-Safe Gathering When Not Everyone Is Vaccinated. Without strong national guidance, states containment policies have varied widely. Yes In fact, the researchers calculated that for every 1% increase in wearing a mask in September, the odds of having high state-wide COVID-19 rates dropped by 26%. And the more swiftly they can act, the shorter any lockdown-style policies need to be. The strongest association was for mask adherence in September; for every 1% increase in average adherence, the odds of a high COVID-19 case rate decreased by 26%. As of Aug. 3, Louisiana is under a temporary statewide mask mandate required of all people, including those who are vaccinated, when indoors. Logistic regression models were used to estimate the odds ratio and 95% confidence intervals for high case rates in the subsequent month associated with average mask adherence (as a continuous variable). 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. The question is and Im sure thats the conversation now happening in the halls of power what do we do next? 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. 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. Our study was also limited by the lack of information on accessibility of COVID-19 testing; if less accessible testing is associated with less mask adherence, the associations we report here may be under-estimates. Read on to find out whyand to ensure . For each month, the distributions of mask adherence across all 50 states and D.C. were categorized into quartiles, meaning the cut-off values for each quartile may be different from one month to another. When the state faced a surge of cases over the summer, the governor closed bars and placed limits on restaurant capacity. Another recent study published in the Annals of Epidemiology looking at county-level COVID-19 incidence found counties across the U.S. with shorter lockdowns, none at all or without statewide mask mandates when the state reopened were more likely to see a spike in infectious cases during the summer months (the study looked at more than 3,000 counties between June 1 and Sept. 30).
