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. PLOS ONE promises fair, rigorous peer review, 3.1.2023 9:15 AM, Joe Lancaster Odds ratios and 95% confidence intervals for average mask adherence and mask policy for the general public are associated with high COVID-19 rates in the subsequent month (Table 3). 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. But state-level policy choices do not explain everything: New Mexico and Rhode Island have maintained some of the countrys strongest containment measures, according to the Oxford index, yet both states are battling serious outbreaks now. "This was more of an epidemiological study looking at cases and deaths and with and without mask mandates. And in the Germancity of Jena, first in the country to implement public mask wearing last April, masks led to a 75% decrease in new COVID-19 cases in little under three weeks, one December study found. The mandate will still require masks where . Thus, adherence to mask wearing in public remains a challenge for mitigating the spread of COVID-19. For mask policy and adherence in September in relation to high COVID-19 rates in October, collinearity caused the odds ratio to flip. When Youve Been Fully Vaccinated. The pandemic has eased, but not the compulsion of many Americans to cover their faces. 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. 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. Thus, subsequent comparisons of states with high COVID-19 rates by month focused on July, August, September and October. When cases first peaked in the United States in the spring, there was no clear correlation between containment strategies and case counts, because most states enacted similar lockdown policies at the same time. We abstracted daily percentages of the population who say they always wear a mask in public. May 16, 2021 / 7:07 AM / CBS News. 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 Kentucky senator presses on with his fight against the federal governments Covid response. When mask adherence dropped in September, COVID-19 cases increased in October. The Centers for Disease Control & Prevention (CDC) recently relaxed their COVID-19 guidelines, allowing fully vaccinated people to forego masks outside. Brooks JT & Butler JC. 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. Investigation, Weak recent containment measures and many cases. Indeed, issuing such a policy is not the same as successfully implementing it. We divided the monthly number by 2.2 to obtain the number in a two-week period (43,088). Methodology, Many experts acknowledge that the rise and fall of waves is a bit of a mystery.". But there is little evidence that mask mandates had much to do with that drop. 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. Heres How Doctors With Kids Are Navigating the New Mask Guidance. Laboratory studies indicate that masks, especially N95 respirators, can help reduce virus transmission. Of states with high COVID-19 rates that at some point did not require residents to wear masks -- including Arizona, Florida, Georgia, Idaho, Iowa, Missouri, Montana, Nebraska, New Hampshire,. 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. 2023 Manhattan Institute for Policy Research, Inc.

Indeed, associations between mask policy, adherence and other factors may be obscured in states with many high density and low density areas. 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. https://doi.org/10.1371/journal.pone.0249891.t002. When the outbreak slammed the New York City area in March and April, leaders locked down. But "few studies assessed compliance to mask wearing policies or controlled for the possible influence of other preventive measures such as hand hygiene and physical distancing.". For every 1% increase in average adherence in June, the fully adjusted odds ratios for high COVID-19 in July was 0.95, indicating a protective effect against high COVID-19 rates. 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.

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. 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%. Eleven states had no stay-at-home order, 15 had no mask policy, and four states had low adherence throughout this six-month period. For more information about PLOS Subject Areas, click 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. Formal analysis, Charlie B. Fischer, But even allowing for differences in testing rates, the similarity in case trends is striking. So could age demographics: The median age of Florida's population is 42.5, compared to 37 in California. (Though todays ruling by U.S. District Judge Kathryn Kimball Mizelle in Tampa, declaring the Biden administrations mask mandate for public transportation unlawful, comes as welcome news.)

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. Both mask policy and mask adherence for states and D.C. were cross-tabulated with high case rates in the subsequent month. 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. R-0 may be the most important scientific term youve never heard of when it comes to stopping the coronavirus pandemic.

Mask wearing has been advocated by public health officials as a way to reduce the spread of COVID-19 [35]. https://doi.org/10.1371/journal.pone.0249891.t001. Vaccinated persons can carry and spread the virus.". 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. If this is true, we would expect associations between mask adherence and high COVID-19 rates to be even stronger. Mask adherence was classified as low if in the lowest quartile and as high if in the highest quartile. 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. 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.. Methodology, 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. After the pandemic, a survey of gains and losses. Even as more and more states encourage or even mandate mask wearing, many citizens still resist the notion. 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]. Yes "The probability of becoming a rapid riser county was 43% lower among counties that had statewide mask mandates at reopening," the researchers reported. In the summer of 2020, Politico praised Rhode Islands wear-your-damn mask policy in an article headlined, How the Smallest State Engineered a Covid Comeback.

States with mask mandates saw higher mask adherence. The CDC's report is the latestin a growing body of evidence establishing mask mandates as an effective strategy in curbing the virus. A recent study shows that states with high levels of mask-wearing reported fewer COVID-19 cases last summer. Adherence to public policy is influenced by a complex interplay of factors such as public opinion, cultural practices, individual perceptions and behaviors [11], which are difficult to quantify. To reduce the rate of COVID-19 cases nationwide, Werler says people need to wear their masks. States are issuing a new wave of mask mandates and social restrictions as record numbers of Covid-19 hospitalizations and soaring daily cases strain US medical systems. The current surge is worst in places with few containment measures. But a new study examines how the value of these actions also came with costs. 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. Is the Subject Area "COVID 19" applicable to this article? 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. 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. Currently, patients, visitors and staff members at UCHealth are required to wear a mask at all times.

Indeed all 13 states in the low mask adherence group in September had high COVID-19 rates in October. The proportions of states with high COVID-19 rates are shown for those in the low and high quartiles of mask adherence in the preceding month (Fig 1). 2023 Dotdash Media, Inc.
