Influenza is rising rapidly across the U.S., and headlines about H3N2 and “new variants” are everywhere. In this episode, I break down what the data actually show, what’s driving this flu season, what H3N2 subclade K really means, how well the flu shot is holding up (spoiler- it's doing fine!), and what matters most for protecting your family. Using current CDC surveillance data and real-world vaccine effectiveness, we put this season into clear perspective. I also share how our household is thinking about and managing play dates, preschool and traveling during an active flu season.

In this episode of Transmissible, we revisit the lifeand work of Dr. John Snow, often called the father of modern epidemiology, to explore why public health history still matters. Long before germ theory was widely accepted, Snow used careful observation, data mapping, and skepticism ofconventional wisdom to trace a deadly cholera outbreak in 19th-century London to a single contaminated water pump. But this episode goes beyond the famous Broad Street map. We examine what Snow’s approach teaches us about evidence-based decision making and the social and political forces that shape public health responses. From resistance to new ideas to the consequences of acting too late, Snow’s story offers manyyy parallels to modern outbreaks, misinformation, and policy debates. So grab a coffee and come hangout!

In this episode we dive into the strange and fascinating world of Alpha-gal syndrome (AGS), the delayed meat allergy that can appear after a tick bite. We talk through what AGS actually is, how ticks (lone star, blacklegged and western blacklegged ticks) introduce it into the body, and why some people develop an allergic reaction hours after eating red meat. You will hear about the symptoms people notice most often and the practical steps you can take to protect yourself from this unusual tickborne illness.

In this episode, I break down how to identify your actual dream job in public health using a simple “mental algorithm” so you’re not just scattering applications into the void, but moving with clarity and purpose toward a career that actually excites you. We talk honestly about the brutal November 2025 public health job market and how to think in terms of transferable skills. I walk you through how to network without being awkward or apologetic, including specific outreach emails (that you can use!) using my E.A.S.Y. framework (Establish, Ask, Simplify, Yield). Finally, I rapid-fire a huge list of public health job titles and organizations you can plug into job boards right away and invite listeners to email me for resume and job-hunt questions.

In January 1925, a deadly diphtheria outbreak threatened the small, frozen town of Nome and the only hope was antitoxin that had to be rushed across Alaska by dog sled in the middle of a massive, subzero blizzard. In this episode, we break down the science of diphtheria, the relay that became known as the Great Serum Run, and the real story behind Togo, Balto, and the race that saved lives.

Phototherapy is one of the most effective and quietly revolutionary treatments in public health. Every year, hundreds of thousands of newborns around the world develop severe jaundice and for most, a simple blue light can prevent irreversible brain damage or even death. But access to that light isn’t universal. In this episode, we explore the science of jaundice and bilirubin, why newborns are particularly vulnerable, describe the mechanism by which blue-green light helps clear toxic levels from the body, and the global inequality in access to this life-saving intervention. We also highlight public health wins, like the innovative Crib A’Glow device and impactful interventions in countries like Myanmar. From the history of phototherapy’s discovery in 1950s England to the modern challenges faced in low-resource settings, this episode brings you deep into the intersection of neonatal care, technology, and global health.

In this episode of Transmissible, we take a critical, evidence-based look at the claim that vaccines cause autism — and examine how this misconception gained traction. We systematically review both methodologically sound and methodologically flawed studies, highlighting key differences in study design, bias, confounding, and statistical interpretation. We’ll break down epidemiologic study types (including cohort studies, case-control studies, ecological studies, and retrospective studies), demystify essential statistical concepts like relative risk, odds ratios, and confidence intervals, and clarify the crucial distinction between correlation and causation. All explanations are presented in plain language without sacrificing scientific rigor. No judgment, just facts. Whether you're an epidemiologist, a healthcare professional, or someone seeking to better understand how scientific evidence is evaluated, this episode provides a clear, grounded analysis of one of the most persistent myths in public health.

For years, parents were told to avoid peanuts in infancy to prevent allergies. But the groundbreaking LEAP study flipped that advice on its head, showing that early peanut introduction can dramatically reduce peanut allergy risk by over 80%. In this episode of Transmissible: A Public Health Podcast, we dive into how this discovery became a major public health win, changing national guidelines, reducing healthcare costs, and reshaping how we think about food allergy prevention.

In this special mini-episode of Transmissible, host Jessica shares a heartfelt thank-you to the hardworking federal employees and contractors at the CDC. Amid heated online rhetoric and job eliminations, Jessica, who has worked extensively with CDC in laboratories, international training, and emergency responses, sets the record straight about what these professionals actually do.

Norovirus—often called the perfect pathogen—is one of the leading causes of acute gastroenteritis outbreaks worldwide. Responsible for widespread illness across all age groups, it remains a major cause of childhood and endemic infections. Originally described as winter vomiting disease due to its seasonal surges, norovirus is infamous for its rapid spread, low infectious dose, and resistance to disinfection. In this episode of Transmissible: A Public Health Podcast, host and scientist Jessica Stahl breaks down what makes norovirus so uniquely contagious, how it wreaks havoc on cruise ships, in schools, and in prisons, and why it continues to be a persistent public health challenge.Citations and additional reading:Norovirus | Norovirus | CDCNorovirus (vomiting bug) - NHShttps://academic.oup.com/jid/article-abstract/205/11/1622/844989?redirectedFrom=fulltext Norovirus Disease in the United States - PMCEID_9-13_NorovirusInTheUnitedStates.pdfNorovirus: Facts and Reflections from Past, Present, and Future - PMC Legal Disclaimer: The information provided in Transmissible: A Public Health Podcast is for informational and educational purposes only and should not be considered medical advice.
