Too Clean to Fight Back: How America's War on Germs May Be Weakening the Immune Systems It Means to Protect

Decades of antimicrobial products, sterilized surfaces, and germ-phobic habits have reshaped the American home into a near-sterile environment—but immunologists are raising urgent questions about what that cleanliness is costing us. The hygiene hypothesis, once a fringe concept, has accumulated enough evidence to warrant serious reconsideration of how we define 'safe' living. Understanding the line between protective sanitation and immunological deprivation may be one of the more consequential p

Left Behind by the Numbers: The Americans Suffering From Infections Too Rare to Fund, Too Obscure to Treat

For patients with low-prevalence infectious diseases, the medical system offers a frustrating paradox: their conditions are real, often debilitating, and poorly understood—not because they defy scientific inquiry, but because the economics of research funding rarely justify the investment. Across the United States, thousands of individuals navigate a healthcare landscape where their infections lack approved treatments, trained specialists, and in some cases, even reliable diagnostic criteria. Th

Pandemic Isolation and the Price of Protection: Rethinking Immunity After Years of Reduced Pathogen Exposure

During the height of the COVID-19 pandemic, lockdowns and masking dramatically reduced Americans' exposure to common respiratory pathogens — but that protection may have come with a hidden cost. The concept of 'immunity debt' suggests that populations deprived of routine microbial encounters are now facing heightened susceptibility to seasonal viruses. Understanding what the evidence actually shows may help Americans navigate the ongoing recalibration of their immune defenses.

Ticks Without Borders: The Expanding Geography of Vector-Borne Disease in a Warming United States

Warming winters and shifting ecosystems are enabling disease-carrying tick populations to colonize American regions where they were once rarely encountered, bringing Lyme disease, Powassan virus, and other serious infections into communities with little historical exposure and limited clinical preparedness. The public health implications are significant, and the window for proactive response is narrowing. Here is what the surveillance data shows — and what can be done about it.

Vaccinated and Still Infected: Understanding Why Breakthrough Cases Don't Mean Vaccines Are Failing

Breakthrough infections in highly vaccinated populations have generated widespread confusion and, in some quarters, eroded public trust in immunization programs. Yet the science tells a more nuanced story—one in which vaccines continue to perform a critical protective function even when they do not prevent infection entirely. Understanding the biological mechanisms at work is essential for making sense of what vaccines were always designed to do.

From Forest to Front Door: The Ecological Chain That Brings Animal Viruses Into Human Communities

Most of the infectious diseases that have reshaped human history did not originate in people. They crossed into human populations from animals, carried along pathways shaped by land use, trade, agriculture, and ecological disruption. Examining the predictable patterns behind these spillover events—from COVID-19 to avian influenza—reveals not only where the next threat is likely to emerge, but also which policy decisions could reduce that risk.

When Antibiotics Fail: Inside the Resistance Emergency Reshaping American Medicine

Antibiotic resistance has crossed a threshold from theoretical concern to clinical emergency, with US hospitals now confronting pathogens that defeat every available treatment. Understanding the molecular mechanics behind resistance—and the agricultural, behavioral, and systemic forces driving it—is essential for anyone invested in the future of American public health.

After the Infection Clears: The Science of Post-Viral Illness and Its Long Shadow on Immune Health

A growing body of research suggests that certain viral infections do not simply resolve—they leave behind lasting alterations to immune architecture, metabolic regulation, and neurological function. Long COVID has brought this phenomenon into sharp focus, but the biological mechanisms at play may apply to a broader category of pathogens with implications for how the US healthcare system diagnoses and treats chronic illness.

The Silent Surge: Why Fungal Infections Are Becoming One of America's Most Underestimated Health Threats

Fungal infections rarely dominate headlines the way viral outbreaks do, yet the CDC has flagged several species—including the drug-resistant Candida auris and the geographically expanding Coccidioides—as urgent public health concerns. For millions of Americans, particularly those with compromised immune systems, these organisms pose life-threatening risks that remain poorly understood by the general public. This feature breaks down what is driving the rise in fungal disease, who faces the greate

What's in a Name? The Science and Ethics Behind Renaming Monkeypox to Mpox

In 2022, the World Health Organization formally adopted 'mpox' as the preferred name for the disease previously known as monkeypox, igniting a broader conversation about how disease labels shape public perception, fuel stigma, and influence outbreak responses. The decision was neither arbitrary nor purely symbolic—it reflected decades of evolving scientific consensus on how infectious disease naming can cause measurable harm. Understanding why names matter in public health is essential to naviga
