Abstract The first quarter of the 21st century was poised to be the era of measles eradication. Following the successful elimination of the virus from the Americas in 2016 and the achievement of elimination status in numerous European nations, the global health community anticipated a gradual march toward the total suppression of the measles virus (MeV). However, the period spanning 2024 to early 2026 has witnessed a catastrophic reversal of these gains. This report provides

Introduction: The Mortality Paradox In the discourse of the twenty-first century, the narrative of climate change is often written in the language of catastrophe. As global mean surface temperatures breached 1.55°C above pre-industrial levels in recent years, the physical evidence of a warming planet has become undeniable. 1  Glaciers are retreating, sea levels are rising, and the thermodynamic potential for violent weather is increasing. Yet, a paradox lies at the heart of o

I. Introduction: The Davos Divergence on Global Health On January 23, 2026, the architecture of international health governance underwent a seismic structural fracture, realized not on the battlefields of conventional warfare, but in the sterile, high-altitude conference rooms of Davos, Switzerland, and the bureaucratic corridors of Washington, D.C. In a synchronized display of diverging foreign policies that underscored the profound polarization of the American polity, the S

Abstract The reappearance of the Nipah virus (NiV) in West Bengal, India, in January 2026 marks a significant epidemiological event, breaking a nineteen-year period of relative silence in the eastern region of the subcontinent. This report provides an exhaustive examination of the outbreak, contextualizing it within the broader history of Henipavirus  emergence. We analyze the specific virological characteristics of the Bangladesh/India strain (NiV-B), contrasting its transmi

Abstract In January 2026, the European veterinary community confronted a pivotal shift in the epidemiological landscape of Highly Pathogenic Avian Influenza (HPAI). The Dutch Food and Consumer Product Safety Authority (NVWA) reported the detection of antibodies against the H5N1 virus in a dairy cow in the province of Friesland. This event, confirmed through rigorous serological testing by Wageningen Bioveterinary Research (WBVR), represents the first documented evidence of H5

1. Introduction The winter of 2025-2026 has marked a pivotal moment in the post-pandemic trajectory of seasonal respiratory viruses. After several years of disrupted seasonality and suppressed circulation following the global emergence of SARS-CoV-2, influenza has returned with a distinct and challenging character. In the United Kingdom, the season has been defined by an unusually early onset and a rapid acceleration of cases, driven primarily by a drifted genetic variant of

Abstract On January 22, 2026, the global health architecture underwent its most significant structural rupture since the end of the Second World War. The United States of America, historically the principal architect and financier of the World Health Organization (WHO), formally finalized its withdrawal from the agency. 1  This event, precipitated by Executive Order 14292 signed by President Donald Trump on January 20, 2025, concluded a mandatory one-year notification period

Introduction: The Convergence of Ideology and Austerity In January 2026, the trajectory of the HIV/AIDS epidemic in the United States shifted violently. For decades, the national strategy relied on a bipartisan consensus that prioritized viral suppression through robust federal funding and state-level cooperation. That consensus has fractured. A simultaneous contraction of federal support, delineated in the Trump administration's Fiscal Year 2026 budget, and a drastic restruc

1. Introduction: The Threshold of a New Climatic Era As the calendar turned to January 2026, the global scientific community and policymakers found themselves navigating a landscape that had fundamentally shifted from the theoretical warnings of the early 21st century to the visceral reality of a planet in flux. The year 2025 concluded not merely as another data point in the relentless upward march of global temperatures but as a definitive marker of a new climatic regime. Cl

1. Introduction: The Anthropocene and the Biological Siege The history of human civilization is, in many respects, a history of ecological restructuring. From the Neolithic Revolution to the industrial sprawl of the twenty-first century, our species has systematically altered the biosphere to maximize resource extraction and settlement space. However, this domination of the landscape has precipitated a cascade of unintended biological consequences, nowhere more acute than in

Abstract By the commencement of 2026, the scientific narrative surrounding microplastics and nanoplastics (MNPs) had shifted from ecological observation to an urgent biomedical crisis. A succession of high-profile studies purported to establish the systematic bioaccumulation of synthetic polymers within the human brain, heart, bloodstream, and reproductive organs. These findings, suggesting that human tissue could contain up to 0.5 percent plastic by weight, triggered global

Abstract The governance of climate change in the United States has historically been characterized by oscillation, but the era spanning the first and second terms of the Trump administration (2017–2021; 2025–Present) represents a structural decoupling from the global decarbonization trajectory. This report provides an exhaustive examination of the policy mechanisms employed to dismantle the U.S. climate regulatory architecture, ranging from the "Energy Dominance" doctrine of

Abstract The inauguration of Donald J. Trump for a second term in January 2025 initiated the most profound and rapid restructuring of the United States federal public health apparatus in its history. Guided by the ideological framework of the "Make America Healthy Again" (MAHA) movement and the administrative blueprint of Project 2025, the administration has systematically dismantled the centralized, consensus-driven model of disease control that characterized the post-war er

Abstract As the United States enters the second week of January 2026, the nation’s public health apparatus faces a converging crisis of biological evolution, epidemiological acceleration, and profound policy recalibration. The 2025–2026 influenza season has distinguished itself rapidly as a period of significant peril for the pediatric population. Surveillance data through the week ending January 3, 2026 (Week 53), reveals a sharp, accelerating trajectory in pediatric mortali

Abstract The operationalization of artificial intelligence (AI) within the National Oceanic and Atmospheric Administration (NOAA) represents a paradigmatic inflection point in the history of environmental prediction. In late 2025, NOAA formally deployed a new suite of forecast systems: the Artificial Intelligence Global Forecast System (AIGFS), the Artificial Intelligence Global Ensemble Forecast System (AIGEFS), and the pioneered Hybrid Global Ensemble Forecast System (HGEFS

Abstract The trajectory of the American opioid epidemic, a public health catastrophe that has claimed over a million lives since the turn of the millennium, has historically been defined by a grim and relentless ascent. From the prescription pill mills of the early 2000s to the heroin surge of the 2010s and the synthetic saturation of the 2020s, the mortality curves have pointed inexorably upward. However, provisional data emerging from the Centers for Disease Control and Pre

1. The Fragile Ecosystem of Public Health: Enter, CIDRAP In the wake of the COVID-19 pandemic, the global health community faces a paradoxical reality. While scientific innovation has delivered vaccines at unprecedented speeds, the systems designed to deliver these life-saving tools—and the public trust required to sustain them—are fracturing. It is within this volatile landscape that the Center for Infectious Disease Research and Policy (CIDRAP) at the University of Minnesot

1. Introduction: The Complex Respiratory Landscape of Winter 2025-2026 As the United States progresses through the winter of 2025-2026, the public health narrative regarding Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has fundamentally shifted. No longer defined by the singular, catastrophic waves of mortality that characterized the early 2020s, the pandemic has transitioned into a complex endemic phase. This new era is marked by predictable seasonal surges,

Introduction: The Weight of the Seventh IPCC Cycle The Intergovernmental Panel on Climate Change (IPCC) has formally entered its Seventh Assessment Cycle (AR7), a distinct operational phase that arrives at a moment of profound convergence between physical inevitability and political urgency. As the global scientific community transitions from the conclusive findings of the Sixth Assessment Report (AR6)—which unequivocally established the reality of anthropogenic warming—into

Abstract As the world transitions through the mid-2020s, the ubiquitous presence of microplastics (MPs) and nanoplastics (NPs) has evolved from a recognized ecological contaminant into a defining marker of the Anthropocene and a critical public health emergency. This report provides an exhaustive analysis of the state of plastic pollution as of early 2026, synthesizing pivotal data from the 2024–2025 period that has fundamentally reshaped our understanding of bioavailability,
