Changes in Self-Reported Mask Use After the Lifting of State-Issued Mask Mandates in 20 US States, February-June 2021.

Objective: In April 2020, the US Centers for Disease Control and Prevention (CDC) recommended community masking to prevent the transmission of SARS-CoV-2. Since then, a total of 39 US states and DC issued mask mandates. Despite CDC recommendations and supporting evidence that masking reduces COVID-19 community transmission, from January to June 20, 2021 states lifted their mask mandates for all individuals.

Upholding Tribal Sovereignty in Federal, State, and Local Emergency Vaccine Distribution Plans.

Cross jurisdictional collaboration efforts and emergency vaccine plans that are consistent with Tribal sovereignty are essential to public health emergency preparedness. The widespread adoption of clearly written federal, state, and local vaccine plans that address fundamental assumptions in vaccine distribution to Tribal nations is imperative for future pandemic response.

Emergency powers and the pandemic: Reflecting on state legislative reforms and the future of public health response.

The first 2 years of combatting the COVID-19 pandemic necessitated an unprecedented use of emergency powers. States responded with an equally unprecedented flurry of legislative changes to the legal underpinnings of emergency response and public health authorities. In this article, we provide a brief background on the framework and use of governors and state health officials' emergency powers.

The Association Between State-Issued Mask Mandates and County COVID-19 Hospitalization Rates.

Context: Mask mandates are one form of nonpharmaceutical intervention that has been utilized to combat the spread of SARS-CoV2, the virus that causes COVID-19.

Objective: This study examines the association between state-issued mask mandates and changes in county-level and hospital referral region (HRR)-level COVID-19 hospitalizations across the United States.

Design: Difference-in-difference and event study models were estimated to examine the association between state-issued mask mandates and COVID-19 hospitalization outcomes.

Trends in Percentages of the US Population Covered by State-Issued COVID-19 Nonpharmaceutical Interventions, March 1, 2020-August 15, 2021.

Trends in the percentages of the US population covered by state-issued nonpharmaceutical interventions (NPIs), including restaurant and bar restrictions, stay-at-home orders, gathering limits, and mask mandates, were examined by using county-specific data sets on state-issued orders for NPIs from March 1, 2020, to August 15, 2021. Most of the population was covered by multiple NPIs early in the pandemic. Most state-issued orders were lifted or relaxed as COVID-19 cases decreased during summer 2020.

The Differential Impact of Reopening States With and Without COVID-19 Face Mask Mandates on County-Level Consumer Spending.

Objectives: By the end of 2020, 38 states and the District of Columbia had issued requirements that people wear face masks when in public settings to counter SARS-CoV-2 transmission. To examine the role face mask mandates played in economic recovery, we analyzed the interactive effect of having a state face mask mandate in place on county-level consumer spending after state reopening, adjusting for county rates of new COVID-19 cases and deaths, time trends, and county-specific effects.

Methods: We collected county-specific data from state executive orders, consumer spending data from the Opportunity Insights Economic Tracker, and COVID-19 case and death data from the Centers for Disease Control and Prevention COVID-19 tracker.

Association of Trends in Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Seroprevalence and State-Issued Nonpharmaceutical Interventions: United States, 1 August 2020 to 30 March 2021.

Background: We assess if state-issued nonpharmaceutical interventions (NPIs) are associated with reduced rates of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection as measured through anti-nucleocapsid (anti-N) seroprevalence, a proxy for cumulative prior infection that distinguishes seropositivity from vaccination.

Methods: Monthly anti-N seroprevalence during 1 August 2020 to 30 March 2021 was estimated using a nationwide blood donor serosurvey. Using multivariable logistic regression models, we measured the association of seropositivity and state-issued, county-specific NPIs for mask mandates, gathering bans, and bar closures.

Social vulnerability and county stay-at-home behavior during COVID-19 stay-at-home orders, United States, April 7-April 20, 2020.

Purpose: Early COVID-19 mitigation relied on people staying home except for essential trips. The ability to stay home may differ by sociodemographic factors. We analyzed how factors related to social vulnerability impact a community's ability to stay home during a stay-at-home order.

The Impact of Covid-19 State Closure Orders on Consumer Spending, Employment, and Business Revenue.

Context: In response to the COVID-19 pandemic, states across the United States implemented various strategies to mitigate transmission of SARS-CoV-2 (the virus that causes COVID-19).

Objective: To examine the effect of COVID-19-related state closures on consumer spending, business revenue, and employment, while controlling for changes in COVID-19 incidence and death.

Design: The analysis estimated a difference-in-difference model, utilizing temporal and geographic variation in state closure orders to analyze their impact on the economy, while controlling for COVID-19 incidence and death.

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 1-December 31, 2020.

CDC recommends a combination of evidence-based strategies to reduce transmission of SARS-CoV-2, the virus that causes COVID-19 (1). Because the virus is transmitted predominantly by inhaling respiratory droplets from infected persons, universal mask use can help reduce transmission (1). Starting in April, 39 states and the District of Columbia (DC) issued mask mandates in 2020.

Differences in rapid increases in county-level COVID-19 incidence by implementation of statewide closures and mask mandates - United States, June 1-September 30, 2020.

Background And Objective: Community mitigation strategies could help reduce COVID-19 incidence, but there are few studies that explore associations nationally and by urbanicity. In a national county-level analysis, we examined the probability of being identified as a county with rapidly increasing COVID-19 incidence (rapid riser identification) during the summer of 2020 by implementation of mitigation policies prior to the summer, overall and by urbanicity.

Methods: We analyzed county-level data on rapid riser identification during June 1-September 30, 2020 and statewide closures and statewide mask mandates starting March 19 (obtained from state government websites).

Decline in COVID-19 Hospitalization Growth Rates Associated with Statewide Mask Mandates - 10 States, March-October 2020.

SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), is transmitted predominantly by respiratory droplets generated when infected persons cough, sneeze, spit, sing, talk, or breathe. CDC recommends community use of face masks to prevent transmission of SARS-CoV-2 (1). As of October 22, 2020, statewide mask mandates were in effect in 33 states and the District of Columbia (2).

Governors' Use of Executive Orders and Proclamations in Hurricane Response, 2006-2018.

Hurricanes can destroy or overwhelm communities and cause or exacerbate health conditions. Legal mechanisms and practices may aid or impede hurricane response. In the United States, where states have primary public health responsibility, state governors possess legal powers to address hurricanes.

Hurricane Evacuation Laws in Eight Southern U.S. Coastal States - December 2018.

National Preparedness month is observed every September as a public service reminder of the importance of personal and community preparedness for all events; it coincides with the peak of the hurricane season in the United States. Severe storms and hurricanes can have long-lasting effects at all community levels. Persons who are prepared and well-informed are often better able to protect themselves and others (1).

Timing of State and Territorial COVID-19 Stay-at-Home Orders and Changes in Population Movement - United States, March 1-May 31, 2020.

SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), is thought to spread from person to person primarily by the respiratory route and mainly through close contact (1). Community mitigation strategies can lower the risk for disease transmission by limiting or preventing person-to-person interactions (2). U.

Timing of Community Mitigation and Changes in Reported COVID-19 and Community Mobility - Four U.S. Metropolitan Areas, February 26-April 1, 2020.

Community mitigation activities (also referred to as nonpharmaceutical interventions) are actions that persons and communities can take to slow the spread of infectious diseases. Mitigation strategies include personal protective measures (e.g.

Emergency Declarations for Public Health Issues: Expanding Our Definition of Emergency.

Emergency declarations are a vital legal authority that can activate funds, personnel, and material and change the legal landscape to aid in the response to a public health threat. Traditionally, declarations have been used against immediate and unforeseen threats such as hurricanes, tornadoes, wildfires, and pandemic influenza. Recently, however, states have used emergency declarations to address public health issues that have existed in communities for months and years and have risk factors such as poverty and substance misuse.

Judicial Opinions Arising from Emergency Preparedness, Response, and Recovery Activities.

This article describes and analyzes the body of emergency preparedness, response, and recovery litigation that has arisen since the September 11, 2001, terrorist attacks. Search terms were developed to identify judicial opinions related to emergency preparedness, response, and recovery activities. Using the Thomson Reuters Westlaw legal database, searches were conducted to collect judicial opinions related to disasters that occurred in the United States between September 11, 2001, and December 31, 2015.

An Assessment of State Laws Providing Gubernatorial Authority to Remove Legal Barriers to Emergency Response.

Governors play a fundamental role in emergency preparedness and can help facilitate rapid responses to emergencies. However, laws that operate successfully under normal circumstances can inadvertently create barriers during emergencies, delaying a timely response. State laws could thus limit, or even prohibit, necessary response efforts.

Transitioning From Paper to Digital: State Statutory and Regulatory Frameworks for Health Information Technology.

Objectives: In all health system sectors, electronic health information (EHI) is created, used, released, and reused. We examined states' efforts to address EHI uses in law to provide an understanding of the EHI legal environment.

Methods: Attorney researchers used WestlawNext to search for EHI-related statutes and regulations of the US states, US territories, and the District of Columbia in effect as of January 2014.
