The crisis spurred by the pandemic of COVID-19 has revealed weaknesses in our epidemiologic methodologic corpus, which scientists are struggling to compensate. This article explores whether this phenomenon is characteristic of pandemics or not. Since the emergence of population-based sciences in the 17th century, we can observe close temporal correlations between the plague and the discovery of population thinking, cholera and population-based group comparisons, tuberculosis and the formalization of cohort studies, the 1918 Great Influenza and the creation of an academic epidemiologic counterpart to the public health service, the HIV/AIDS epidemic, and the formalization of causal inference concepts. The COVID-19 pandemic seems to have promoted the widespread understanding of population thinking both with respect to ways of flattening an epidemic curve and the societal bases of health inequities. If the latter proves true, it will support my hypothesis that pandemics did accelerate profound changes in epidemiologic methods and concepts. •Catastrophic pandemics since the 17th century appear to have spurred innovative methods, concepts, and institutions in epidemiology.•The plague, cholera, tuberculosis, influenza, and HIV/AIDS left a longstanding imprint on epidemiologic methods and concepts.•Pandemics may generate an urgent need for methods that overcome the inadequacy of older methods.•COVID-19–specific contribution could be a greater understanding of population thinking beyond academic and professional circles.

Since taking office, the new US administration has issued numerous executive orders (e.g., order 14151 and 14168 of January 20, 2025) that significantly impact public health research. At this stage, the Journal has added substantial value to the article, ensuring its clarity and scientific integrity. [...]a final article is not solely the work of the authors but a vetted scientific contribution in which the Journal plays a crucial role. Examples include McCarthy-era blacklisting of scientists suspected of communist affiliations, which led to academic dismissals and funding cuts; neglect and underfunding of AIDS research in the 1980s, which hindered studies on LGBTQ1 health; government-imposed restrictions on discussing contraception and reproductive health in federally funded public health programs; and censorship of climate change science, notably between 2017 and 2021, when references to climate change were systematically removed from multiple federal agency websites and political interference affected climate research.

ABOUT THE AUTHOR Alfredo Morabia is AJPH editor-in-chief (2015-2025) and is with the Barry Commoner Center for Health and the Environment, Queens College, City University of New York, and the Department of Epidemiology, Mailman School of Public Health, Columbia University. With support from the Robert Wood Johnson Foundation, we conducted a two-year workshop on DEI in scientific publishing, culminating in two landmark documents: a scoping review (in press) and the Ensuring Quality in Scientific Publications Through Inclusivity and Transparency (EQSPI) platform (Loui and Morabia, ?. [...]the relationship with APHA leadership, particularly through monthly meetings with the executive director, Dr. Georges Benjamin, and the advisory role of the APHA Editorial Board, have been mutually enriching. Through APHA, AJPH had direct access to the entire ecosystem of public health: from the surgeon general and leaders of the US Department of Health and Human Services, the Centers for Disease Control and Prevention, the National Institutes of Health, the Occupational Safety and Health Administration, and the US Food and Drug Administration to state and local health departments and academic institutions.

Aaron was 86 years old and likely experienced cardiac arrest or sudden death, a common occurrence at his age. Aaron's risk of death that week was high, irrespective of his vaccination status. 2 patterns identified through this study suggest variations in the distribution of widely used determinants of health, some 80 years after the HOLC [Home Owners Loan Corporation] grading system was implemented. Public health is a science, grounded in rigorous data analysis and a population-based perspective.

The training must include public health department professionals, pharmacists, nurses, lab technicians, epidemiologists and statisticians, economists, engineers, doctors, nutritionists, dentists, informaticians, and more. [...]protecting public health education is crucial, as is ensuring that leaders and their teams in health institutions possess this expertise. Programs like CEAL (Community Engagement Alliance Against COVID-19 Disparities; https://ajph.aphapublications.org/toc/ ajph/114/S1) and RADx-UP (Rapid Acceleration of Diagnostics for Underserved Populations; https://ajph. aphapublications.org/toc/ajph/112/S9) show how engaging communities protects minoritized populations and counters disinformation. Community engagement is the foundation of a resilient, inclusive public health system.

Unlike research articles, NFTF pieces focus on describing processes in a reproducible way, rather than delving into methods, analysis, and findings. Evaluation and Adverse Effects: Provide evidence on the effectiveness of the intervention and discuss any adverse or unintended consequences, if applicable. (p. 1207) detail the SCALE-UP Utah initiative, a pragmatic clinical trial that promoted COVID-19 testing and vaccination through text messages sent to 107 898 patients across 28 clinics embedded in seven community health centers.

A recent editorial on the Web site of the American Civil Liberties Union (ACLU), representing 6.5 million supporters, should be read as an alarming call for public health because the authoritarian plans proposed by the former president and current presidential candidate are serious: [...]the Supreme Court's Shelby County v Holder decision in 2013 removed the requirement for states with a history of discrimination to obtain federal approval (i.e., \"preclearance\") before changing voting policies. A US Army study showed a 51 percent increase in febrile acute respiratory disease in basic trainees at four army centers living in energy-efficient army bar racks in comparison to trainees living in old \"leaky\" barracks...The scientific underpinnings for solving indoor air quality complaints will only be established by systematic epidemiologic work in conjunction with ventilation engineering and industrial hygiene assessment. Except in cold weather, much artificial cooling is required to remove excessive heat from furnaces, machinery, and solar radiation.

AJPH has been tracking the evolution ofthe public health workforce and has published data showing both the grim2,3 and positive4 trends, identifying causes and solutions.5,6 In this issue, three articles illustrate some ofthe key weaknesses ofthe current situation: threats to community health worker (CHW) retention, lack of appropriate job classifications to enumerate the workforce, and the often neglected issue of chemical exposure. CHWs are frontline public health workers, a core component of public health community engagement.7 According to the US Bureau of Labor Statistics (BLS), there were 67 200 CHWs in 2022, with an expected growth of 14% (or 9400 jobs) from 2022 to 2032 (https://bit.ly/3ssX4Df); their median salary is $46190 peryear ($22.21 per hour). Assessments of public health workforce needs often fail to consider the health and safety dimension ofthe jobs.12 Workers employed in hospitals, health clinics, universities, laboratories, and schools often use chemicals to ensure the cleanliness and hygiene of their buildings or to run their laboratories. Because of these potentially toxic exposures, building maintenance workers, janitors, housekeepers, and lab workers may suffer from occupational ailments ranging from respiratory problems to cancer and endocrinedisrupting exposures.
