| dc.description.abstract | The COVID-19 pandemic has been one of the most significant global health crises in modern history, putting public health systems, economies, and political institutions around the world to the test. In the United States, states implemented a variety of non-pharmaceutical interventions (NPIs), such as mask mandates, stay-at-home orders, travel restrictions, school closures, and limits on gatherings. However, the timing, scope, and enforcement of public health interventions varied significantly between states. This study examines how states responded to the pandemic from March 2020 to October 2021, covering both major waves of COVID-19 and extending beyond the periods analyzed in most existing studies. Drawing on the dataset compiled by Mayer et al. (2022), which tracks weekly state-level policy actions alongside infection and death counts, this research addresses three main questions: (1) Which states were early adopters, late adopters, or non-adopters of NPIs, and what political, economic, and demographic factors explain these differences? (2) How effective were these policies in slowing infections and reducing deaths? (3) How did state politics shape enforcement and influence health outcomes? Using the Policy Innovation and Diffusion framework to guide the policy adoption analysis and an epidemiological approach to evaluate policy effectiveness, this study offers a comprehensive view of how states navigated an evolving crisis. The findings reveal the complex interplay between political context, demographic characteristics, and public health decision-making, and provide lessons for crafting effective, context-specific responses to future public health emergencies. | en_US |
