Thats a huge swing, Werler says. For mask adherence, the cut-off values for the low and high quartiles were 31% and 46% in June, 53% and 72% in July, 55% and 71% in August, and 55% and 68% in September. 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%. 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. Fourteen of the 15 states with no mask wearing policy for the general public for the entire four month period (June through September) reported a high COVID-19 rate. States with stronger policy responses over the long run are seeing comparatively smaller outbreaks. Writing review & editing, Affiliation Higher mask use did not predict lower maximum growth rates, smaller surges, or . No, Is the Subject Area "Public and occupational health" applicable to this article? For a while, the residents were spared. While the downtrend could also have been a result of other countermeasures like social distancing, Kansas' findings mirror observations from other states and countries. States with mask mandates saw higher mask adherence. I just dont know based on reading the OAN summary how they came to the same conclusions because the CDC conclusions were favorable.. 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. When we looked at states with 75% mask adherence (Arizona, Connecticut, Hawaii, Massachusetts, Michigan, New York, Rhode Island, Vermont), we found none had experienced a high COVID-19 rate in the subsequent month. | Sources: Oxford Covid-19 Government Response Tracker, closing bars, restaurants, gyms, theaters and schools, one in 10 North Dakotans have tested positive. 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. Of note, there were no states with 75% in September. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); NEXT: The FBI Seized Almost $1 Million From This Familyand Never Charged Them With a Crime.

The claim that a CDC study found face masks to have a negligible effect on the spread of COVID-19 is FALSE. 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. 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. Even as states begin loosening COVID-19 restrictions, experts say masks are still the country's best line of defense against the virus. Thus, adherence to mask wearing in public remains a challenge for mitigating the spread of COVID-19. 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. They looked at data from April to October 2020. 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. Illinois will lift its face mask requirement on Feb.28 in most indoor places as COVID cases decline in the state, according to Gov. She holds a Masters in Psychology concentrating on Behavioral Neuroscience. Miller, who has tracked pandemic trends for the Brownstone Institute, has assembled the damning evidence in Unmasked: The Global Failure of COVID Mask Mandates. Mask wearing has been advocated by public health officials as a way to reduce the spread of COVID-19 [35]. Germanys stringent policies have made it a consistent media darling. By Lauren Leatherby and Rich HarrisNov. By the time the mandates were introduced in New York and other states in the spring of 2020 (at the left side of the graph), infections had already been declining in those states, and the mandates didnt prevent a surge later that year, when cases rose and fell in nearly identical trajectories regardless of states mask policies. Thank you, {{form.email}}, for signing up. 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. 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. We used state-level data on mask wearing policy for the general public and on proportion of residents who stated they always wear masks in public. Mandating masks gave the illusion of doing something against the virus. When the state faced a surge of cases over the summer, the governor closed bars and placed limits on restaurant capacity. Wearing a mask may still give some people a sense of security, but they could breathe more easily if theyd face the facts. 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. 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. Nedghie Adrien, Roles That period is used as the benchmark against which researchers compared days 21 through 60 before mask mandates were adoptedand the 100 days after. Research suggests that mandatory mask-wearing policies correlated with a lower number of COVID-19 infections and deaths. Many local leaders went further. Instead, it analyzed the connection between mask mandate policies and the rate of new county-level coronavirus cases and deaths. Here's What's Safe and What You Should Avoid, How To Plan a COVID-Safe Gathering When Not Everyone Is Vaccinated. As of yesterday,The New York Times reports, every state that required people to wear face masks in public places and/or in schools during this winter's COVID-19 surge has decided to lift those mandates, with the exception of Hawaii. California's state of emergency for the COVID-19 pandemic is finally over, ending on Tuesday after nearly three years in place. Here's what it could mean for all of us. The 2-week rate in July in Arizona = 43,088 cases/7,278,717 population in 2019 = 0.00592 or 592 per 100,000. Fully vaccinated adults are still wearing masks on their solitary walks outdoors, and officials have beenenforcing mask mandates on airline passengers and on some city-dwellers and students. Monthly COVID-19 case rates (number of cases per capita over two weeks) >200 per 100,000 residents were considered high. To calculate monthly COVID-19 case rates, we abstracted the number of new cases reported by the U.S. Centers for Disease Control and Prevention (CDC) [17] and state population sizes in 2019 [18]. Charlie B. Fischer, "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%]. Our analyses took into consideration the delayed effect of mask wearing and policies on COVID-19 health outcomes. 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.

The current surge is worst in places with few containment measures. Even as more and more states encourage mask wearing [7], many citizens still resist the notion [8]. A recent study shows that states with high levels of mask-wearing reported fewer COVID-19 cases last summer. Centers for Disease Control and Prevention. Just as in the United States, the mask mandates in Germany produced no net benefits but plenty of inconvenience as well as outright harm. Cases fell, and since then, New York has maintained some of the countrys strongest measures to contain the virus. Its Legacy Is Disastrous. 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. Read on to find out whyand to ensure . PLoS ONE 16(4): The same basic pattern was seen in nearly every state. Without strong national guidance, states containment policies have varied widely. 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. "There are over 200 percent more cases in a school (district) that does not have a mask mandate," said Dr. Catherine Troisi, an. 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. + Caption. Our study accounted for temporality by staggering COVID-19 outcome data after adherence measures. Most states imposed tight restrictions in the spring even if they did not have bad outbreaks then. Yes 2021;325(10):998-999. doi:10.1001/jama.2021.1505. 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. But it seems clear that anyone who takes it for granted that mask mandates have played a crucial role in controlling the spread of COVID-19 is making a series of assumptions that are not justified by the evidence. 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. She finds that mask-wearing is still the best course of action for mixed-vaccination status gatherings. But there are still settings where wearing your mask is crucial.

Over a third of states are ending COVID-19 mask mandates. After the pandemic, a survey of gains and losses. Eleven states had no stay-at-home order, 15 had no mask policy, and four states had low adherence throughout this six-month period. According to Werler, Arizona's data was unexpected. 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).

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. The findings were published in the journal PLOS One in April. 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. 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.

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. 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. However, the COVID-19 rates continued to be higher in places with low mask adherence. As of Aug. 3, Louisiana is under a temporary statewide mask mandate required of all people, including those who are vaccinated, when indoors. PLOS ONE promises fair, rigorous peer review, 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. As you can see from the lines' similar trajectories, the mask mandates hardly controlled the virus. All reviews and studies included in this document report on data collected in a time period prior Yes But in each state, as Miller shows, infection rates remained lower in the counties that did not mandate masks. But a new study examines how the value of these actions also came with costs. More could be on the way. The opposite was true for states with mandates. The pandemic planners at the United Kingdoms Department of Health had reached a similar conclusion: In line with the scientific evidence, the Government will not stockpile facemasks for general use in the community. Anthony Fauci acknowledged this evidence early in the pandemic, both in his public comments (Theres no reason to be walking around with masks, he told 60 Minutes) and in his private emails (I do not recommend you wear a mask, he told a colleague, explaining that masks were too porous to block the small Covid virus).

Weak recent containment measures and many cases. Yes We also identified states with average mask adherence 75% in a given month. 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. Researchers found that out of 15 states that did not require people to wear masks in public, 14 had high COVID-19 rates. 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. Data curation, JAMA. 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. 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. Texas locked down in the spring, when it had relatively few cases, then reopened quickly. https://doi.org/10.1371/journal.pone.0249891.t002. No, Is the Subject Area "United States" applicable to this article? | 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.

The authors found that the growth rate of new coronavirus cases and deaths dropped after mask mandates were put in place. 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. Its been largely delegated to a subnational level, to the states, for example, and municipalities to figure it out themselves..

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 transmission. Coronavirus: How R-0 can be used to fight COVID-19. Note: State containment measures are shown from two weeks prior, reflecting what experts say is a lag between new policies and results. 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. here. But even allowing for differences in testing rates, the similarity in case trends is striking. States in COVID-19 high-risk categories are listed in Table 1. https://doi.org/10.1371/journal.pone.0249891.g002. So theres a need to make decisions and be decisive, Dr. El-Sadr said.
