This Podcast Will Kill You

Our tapeworm episode last week mentioned the remarkable finding of tapeworm eggs in a 270 million-year old shark coprolite, that is, fossilized feces. And this certainly wasn’t the first time coprolites have come up on the podcast; we’ve referenced them several times before, mostly when discussing early histories of parasitic worms. But there is so much more to the world of coprolites than just which parasites were found and when. To help us explore all that coprolites can teach us is the world-renowned paleontologist Dr. Karen Chin, Professor at University of Colorado Boulder and Curator of Paleontology at CU-Boulder Museum of Natural History. In this exciting bonus episode, Dr. Chin takes us on a fascinating tour of the what (what are coprolites?), the why (why are they important?), the how (how do feces get preserved?), and the who (who dung it?) of these incredible trace fossils.

We can probably all agree that the thought of a tapeworm hiding out in your gut is not a pleasant one. Nor is the image of tapeworm larvae forming cysts in your muscles, organs, and even your brain. So listening to an entire episode on these parasitic worms? We understand why that may seem like a bit much. But trust us, the world of these worms is too fascinating and important to be missed. In this episode, we break down the biology of the tapeworm species that commonly infect humans and discuss the role of these parasites as a leading infectious cause of epilepsy around the world. Then we venture into the ancient and not-so-ancient history of these tapeworms, starting at “who was infected first - the human or the pig?” and ending with “what was the tapeworm diet all about anyway?” Finally, we wrap up the episode with a look at tapeworm by the numbers today.

The classic tale of epidemiology almost always begins with public health hero John Snow traipsing all over London to track down the source of the 1854 cholera epidemic, ultimately identified as the Broad Street Pump. While Snow’s famous endeavor earned him the title “the father of field epidemiology”, it turns out, as it so often does, that the real story is more complicated. In this bonus episode, we look beyond John Snow to explore the deeper roots of epidemiology with Dr. Jim Downs, Gilder Lehrman-National Endowment for the Humanities Professor of Civil War Era Studies and History at Gettysburg College. Dr. Downs’ latest book, Maladies of Empire: How Colonialism, Slavery, and War Transformed Medicine, reexamines the historical drivers that led physicians to turn their attentions towards the spread of disease in populations. Where does John Snow fit into this revised story of epidemiology? Tune in to find out. See omnystudio.com/listener for privacy information.

[CW: Firsthand account includes description of the death of an infant. Skip approximately first 3 min to avoid.]What comes to mind when you hear the word tetanus? For many people, it’s probably the horrible thought of stepping on a rusty nail or the every-so-often Tdap booster you get at your doctor’s office. Thanks to the wide availability of this incredibly effective vaccine, not many of us have an image of what an infection with tetanus actually looks like or how deadly it can be. But that’s not the case everywhere, especially in places with limited access to these life-saving vaccines. In this episode, we take you through the biology of the spore-forming, soil-dwelling, obligately anaerobic, Gram positive Clostridium tetani and the powerful paralytic neurotoxins it produces. We then venture into the history of this pathogen, a history that includes a tour through early medical texts and a discussion of the origins of epidemiology as viewed through the context of neonatal tetanus in the American South. We round out the episode by reviewing where tetanus still poses a substantial threat today and highlighting some very exciting ways this deadly pathogen may be used to treat cancer! Tune in to gain a newfound respect for this incredible microbe! See omnystudio.com/listener for privacy information.

Chlamydia trachomatis may have stolen the show in our last episode, but there are many other Chlamydiae that deserve some time under the spotlight. In this bonus episode, Dr. Martina Jelocnik (@MartinaJelocnik) and Dr. Sam Phillips (@Sam_Phillips_83) from the University of the Sunshine Coast in Queensland, Australia, join us to chat about some of these other Chlamydia species and the effects they have on wildlife and domestic animals. Curious about koalas and chlamydia? This episode will bring you up to speed on how these charismatic creatures are impacted by Chlamydia pecorum as well as current research efforts towards a vaccine to combat this pathogen. Wondering about psittacosis and birds? Or livestock and Chlamydiae? We’ve got you covered there as well! Tune in this week for a truly fascinating deep dive into the wide world of these pathogens! See omnystudio.com/listener for privacy information.

With this episode, you’re getting much more than you probably bargained for, thanks to the quirks of Chlamydia trachomatis. This small but mighty bacterium can cause a number of different conditions throughout your body, most notably in your eyes and your genital tract, and the resulting infections, if left untreated, can lead to substantial and permanent damage. In this episode, we focus on the two most common forms of chlamydia infection, trachoma (eyes) and chlamydia (genital tract), and discuss the similar pathway through which this bacterium leads to these distinct diseases. While the biology of trachoma and chlamydia may be similar, the history of these two infections could not be more distinct. Tune in to hear what ancient medical texts have to say about trachoma, how surprisingly recently chlamydia was recognized as an STI, and where we stand with these two incredibly common infections today!

[This episode is a re-release of Ep 27 Vaccines Part 2: Have you thanked your immune system lately?, originally published May 21, 2019]Were you stoked about the history and biology of vaccines we covered in part 1, but left with even more questions? Were you really hoping to hear us talk about anti-vaccine sentiment and address misconceptions about vaccines in detail? Did you want even more expert guest insight?! Well then do we have the episode for you! Today, we delve into the history of the “anti-vaccine movement” which, spoiler alert, is nothing new. With the help of Dr. Peter Hotez, Dean of the National School of Tropical Medicine at Baylor College of Medicine in Houston and Co-director of the Texas Children’s Hospital Center for Vaccine Development we address some of the most common concerns and questions that arise about vaccines, their safety, and their efficacy. And finally, we hear from Bill Nye The Science Guy about dealing with the challenges of science communication in the modern world when diseases spread as fast as fake news headlines. Y’all. This is the episode you’ve been waiting for. You can follow Dr. Peter Hotez on twitter @PeterHotez and check out his book “Vaccines Did Not Cause Rachel’s Autism” And you can listen to “Science Rules!” the new podcast from Bill Nye the Science Guy, available now on stitcher https://www.stitcher.com/podcast/stitcher/science-rules-with-bill-nye or wherever you are listening to this podcast!

[This episode is a re-release of Ep 26 Vaccines Part 1: Let's hear it for Maurice, originally published May 14, 2019]The wait is finally over: this week we are very excited to bring you the episode we’ve been teasing for weeks: vaccines! This week and next (you don’t have to wait a full two weeks for the next episode!), we are presenting a two-part series on vaccines. In today’s episode, we dive deep into the biology of vaccines, from how they stimulate your (amazing) immune system to protect you, to how they make you into an almost-superhero, shielding the innocents around you from deadly infections. We take you back hundreds, nay, thousands of years to when something akin to vaccination first began, and then we walk along the long road of vaccine development to see just how massive an impact vaccines have had on the modern world. The best part? We are joined by not one, but two experts from the Bill and Melinda Gates Foundation. Dr. Gail Rodgers and Dr. Padmini Srikantiah explain the process of vaccine development, highlight the challenges of vaccine deployment, and shine a hopeful light on the future of vaccines. And be sure to tune in next week for part 2 where we’ll focus on vaccine hesitancy and address common misconceptions surrounding vaccines in even more depth.

While last week’s episode covered ample ground when it came to lightning strikes, there is so much more to the world of electricity left to explore. Fortunately, there’s a bonus episode for that! This week, we’re joined by a familiar voice, Dr. Timothy Jorgensen, whose previous appearance on the podcast (see Ep 53 Radiation: X-Ray Marks the Spot) helped to lay out the basics of radiation. In this bonus episode, Dr. Jorgensen, Professor of Radiation Medicine and Director of the Health Physics Graduate Program at Georgetown University, returns to the pod to help us dig deeper into the vast topic of electricity. His latest popular science book, Spark: The Life of Electricity and the Electricity of Life, gives us much to talk about, from how electricity works to the difference between direct and alternating current, from electric fish to ECT, and beyond. As an accomplished science writer, Dr. Jorgensen also shares some insights into using storytelling as a teaching tool and advice for those who may want to become better science communicators themselves.

Lightning strikes have an aura of myth and legend around them, and their mystical reputation is inflated by stories that tell of people who, after having been hit by lightning, are suddenly able to speak a new language or play the piano expertly. However, such embellished stories often fail to distinguish truth from fiction and rarely acknowledge the devastating toll that getting struck by lightning can have on your body and mind. Which is where TPWKY hopes to set the record straight. In this episode, we explore what lightning is, how it can cause injuries or death, and what distinguishes it from other electrical shocks. Then, rather than focusing solely on the history of lightning, we take a tour through four vignettes in the broad history of electricity that tell of ways humanity has harnessed it for both bad and good. By the end of the episode, you’ll be shocked by the story of a dentist from Buffalo, electrified with the knowledge of how lightning forms, energized with the current status of lightning around the globe, and left with no resistance to terrible electricity-themed puns.

In last week’s episode, we explored the mysterious world of multiple sclerosis (MS) and the ongoing quest to determine what causes this autoimmune disease. While it’s likely that no one single factor leads to the development of MS, the Epstein-Barr virus (EBV) has long been suspected to play a role in this and many other autoimmune diseases and has also been shown to be involved in several cancers. But why? How is this virus implicated in so many diseases? How does it infect us? What does it do once it’s in our bodies? Dr. Micah Luftig, Associate Professor and Vice Chair in the Department of Molecular Genetics and Microbiology at Duke University, helps to answer these questions and many more about this surprising virus. Not only does Dr. Luftig share his expert knowledge in all things EBV in this interview, he also sheds some light on what a career in academia is like and drops some great advice on how to feel out whether a research career might be right for you.

Like many autoimmune diseases, multiple sclerosis so clearly illustrates how detection and description of a disease only gets us so far when it comes to prevention, treatment, and cure. In the over 150 years since the first comprehensive description of multiple sclerosis, a great deal of progress has been made to understand the what and how of this disease, but many mysteries still abound, especially surrounding the why. In this episode, we explore what we do know about how this disease works, including a discussion about two recent headline-making scientific articles implicating a certain virus in disease onset or progression. We then trace its history all the way from an ice skating saint to a sympathetic sister, and we end the episode by taking measure of the global status of this disease.

We ended our myxoma virus episode on a bit of a cliffhanger, briefly alluding to the emergence of another deadly rabbit virus on the global scene. In this follow-up bonus episode, we take a closer look at this recent arrival, rabbit hemorrhagic disease virus (RHDV), and what its rapid spread around the world has meant for both invasive European rabbits in Australia as well as native rabbit species around the world. Dr. Robyn Hall (@Virologica), veterinary virologist, epidemiologist, and Team Leader of the Rabbit Biocontrol Team at CSIRO in Australia, walks us through how this virus earned the nickname “bunny Ebola”, where it seems to be having the most impact, and what the sudden appearance of a new type of RHDV has taught us about viral evolution and ecological cascades. Then, once we fill up on RHDV facts, we talk favorite viruses, life as a veterinary virologist, and so much more! Tune in wherever you get your podcasts. And check out our website for links to where you can learn more about this fascinating and deadly virus. See omnystudio.com/listener for privacy information.

Invasive rabbits so numerous they form a “gray blanket” across the land. A killer virus, intentionally released to keep the bunnies at bay. An ensuing evolutionary arms race with no end in sight. It sounds more like the premise of a bad sci fi movie rather than a textbook case of biocontrol. But truth, especially in this case, is stranger and even more fascinating than fiction. If this is the first you’re hearing about myxoma virus and its place in the long history of European rabbits in Australia, get ready for a gripping story filled with rabbit facts, discussions about what drives pathogens to be deadly or benign, and philosophical musings about the situational difference between pest, pet, and keystone species. That’s right, we’re heading deep down the rabbit hole with this one. See omnystudio.com/listener for privacy information.

Our episode last week ended on a hopeful note, a rare occurrence for this podcast, and it was due in large part to the incredible decline in reported cases of human African trypanosomiasis (HAT) over the past decade. In this bonus episode, we explore one of the major reasons behind this drop in HAT: the new medication fexinidazole, developed through a partnership between the Drugs for Neglected Diseases initiative (DNDi), a non-profit organization dedicated to developing new treatments for neglected diseases and Sanofi, a French healthcare company. We are thrilled to be joined by two researchers from DNDi, Dr. Nathalie Strub-Wourgaft and Dr. Wilfried Mutombo Kalonji, who share their insights into the challenges associated with bringing a medication all the way from its development stage, to testing it in the field, and finally ensuring that access is provided for those who need it most. We also chat about how this treatment works, the impact that COVID-19 has had on screening efforts for sleeping sickness, the lessons learned from fexinidazole’s development, and so much more. Tune in wherever you get your podcasts! And when you’re finished with the ep, check out this beautiful video from DNDi chronicling the story of fexinidazole: A doctor’s dream: A pill for sleeping sickness.

Here on the podcast, we’re no strangers to multi-host parasites with complicated life cycles, intricate ecologies and dense human histories. But human African trypanosomiasis (HAT) might require the most unpacking yet. In this episode, we do a deep dive into the tsetse fly-transmitted HAT, whose other name, sleeping sickness, doesn’t quite capture just how deadly this parasitic infection can be. First, we ask how these two trypanosomes cause the signs and symptoms they do, especially the strange sleep disruptions that gave this neglected tropical disease one of its names. Then, after a brief detour discussing the fascinating ability of tsetse flies to give live birth, we explore the many political and ecological factors that set the stage for the devastating HAT epidemics of the early 20th century. We wrap up the episode with a look at the current global status of HAT, and with new, effective, and easy-to-administer drugs on the scene along with a downward trend in cases, we’re certainly hopeful for the future elimination of this disease.

Blood tests and liver function results can only tell us part of the story when it comes to the impact that hepatitis B has on people living with the virus. Far too often overlooked is how stigma and discrimination, which we only briefly touched upon in our last episode, contribute to the substantial global burden of disease. In this bonus episode, Dr. Chari Cohen, Senior Vice President of the Hepatitis B Foundation, comes on the pod to chat about the different forms stigma and discrimination can take, how we can get a better sense of their impact, and the key tools in the fight against them. We also seized this opportunity to pick Dr. Cohen’s brain about what it’s like to run a public health non-profit, how much of the job is accurately reflected in the job title, and advice for someone who might be interested in pursuing a career in public health.

This week, we’re dipping a toe back into the vast waters of hepatitis viruses, this time with a focus on hepatitis B. The hepatitis B virus, though second to be named, was first to be discovered, and effective vaccines and treatments have been available for decades. Yet the global prevalence of this virus remains staggering, with nearly 300 million people chronically infected and 1.5 million new infections annually. So what’s going on? In this episode, we weave our way through the complicated biology of this virus and its deadly potential, the strange history of its identification that shows that you don't have to be looking for something to find it, and the current status of this virus that underlines how safe, effective tools for disease prevention are only as good as our delivery infrastructure. We are also so excited to be joined by Dr. Su Wang, Medical Director for the Center for Asian Health & Viral Hepatitis Programs at the Cooperman Barnabas Medical Center and outgoing President of the World Hepatitis Alliance.

Chances are you know someone with endometriosis, or perhaps you’re affected yourself. But despite its incredibly high prevalence, endo remains almost criminally understudied, undertreated, and underacknowledged. In this episode, we aim to shed light on many aspects of endometriosis, first by examining the “what” and “how” of this disease: what’s actually going on inside your body with endometriosis and how does it cause the symptoms that it does? Then we turn our sights to the why, exploring not only the possible evolutionary origins of this disease but also the deep historical roots contributing to the struggle many people still face today in obtaining a diagnosis. We discuss how although hysteria is no longer a valid medical diagnosis, it has left its mark on medicine in the form of implicit bias that leaves many people feeling unlistened to and unbelieved. We then wrap up the episode with a look at endometriosis by the numbers and some current research that leaves us feeling slightly more hopeful about the growing awareness of this disease and the need for effective treatments. See omnystudio.com/listener for privacy information.

In this week’s episode, we cover a bacterium whose recent emergence and rapid spread has been largely an epidemic of our own making. Clostridium difficile isn’t your typical pathogen - in many cases it’s not even considered a pathogen, just a normal member of our gut microbiota. But when something disrupts our gut microbiota, like antibiotics, C. difficile is given the freedom to spread its wings, wreaking deadly havoc on our bodies especially when it refuses to leave. We explore the characteristics of this bacterium that make it such a terrifying public health threat, delve into its recent-but-not-as-recent-as-you-might-think history, and chat about the current status of C. diff before asking the question, “what can poo do for you?” That’s right, we’re taking this opportunity to talk about one of our all-time favorite medical interventions, fecal microbiota transplantation. Helping us navigate the ins and outs of fecal transplants is Dr. Majdi Osman, Chief Medical Officer at OpenBiome, a nonprofit stool bank that aims to expand access to safe fecal microbiota transplantation and fund research into the human microbiome. By the end of this episode, we think you’ll find yourself in awe at the healing powers of poop. See omnystudio.com/listener for privacy information.

We’re back with our first episode of Season 5, and we’re starting off with a bang! Epidemic typhus, that friend of war and famine, may have caused more wartime deaths than all battles combined, and though it may seem like a disease relegated to the past, typhus only needs a minor disruption to turn it into a scourge of the present. In this epic season opener, we turn our sights to the louse-transmitted Rickettsia prowazekii, first diving into the strange and terrible biology of this bacterium before exploring the deep history of this tiny but mighty pathogen. The vast story of typhus takes us on a journey on a ‘coffin ship’ of the Great Irish Famine, through musings of the origins of human body and head lice, to German-occupied Poland during WWII with tales of vaccine sabotage and lice feeding, and finally to the present day, where we discuss the very real threat that epidemic typhus continues to pose. Check out this episode for all you ever wanted to know about epidemic typhus and more! See omnystudio.com/listener for privacy information.

To say that alcohol is a part of human culture is a bit of an understatement. The relationship our species has with alcohol can be traced so far back that we see evidence of it in our DNA, in the way that humans, somewhat unique among mammals, gained the ability to more efficiently metabolize dietary ethanol. But while many of us have personal experience with the effects (and unpleasant aftereffects) that alcohol has on our body, how much do we know about why it makes us feel the way it does? What is alcohol doing to our bodies, to our brains? In this episode, we take a long look at this compound, from the varied effects it has on our bodies to the long history it shares with humans. Tune in to our Season 4 finale to hear why hangovers exist, how fermenting fruits on the forest floor led us to intentional production, and the truth behind all of those headlines advocating for a glass of red wine a day to keep the doctor away.

It’s the summer of 1999 in New York City, and everyone's looking towards the future, towards millennium parties and potential Y2K catastrophes. But if they turned their eyes to the streets around and skies above, they might have seen something else on the horizon, something much more real and alarming than a Y2K glitch: the arrival of West Nile virus. In this episode, we take a close look at the virus whose recent emergence in the Western Hemisphere serves as a crucial reminder of how pathogens know no political boundaries and how working across disciplines is the only way to effectively control and prevent disease outbreaks. We are also so excited to be joined by Dr. Sarah Wheeler, Biologist at Sacramento-Yolo Mosquito and Vector Control District, who talks us through the ecology of this mosquito-borne disease and shares the birds-eye view of the situation in North America. Last but certainly not least, we round out this episode with a delightful and informative song about West Nile virus: West Nile Story by MC Bugg-Z and the Fairfax County Health Department.

Almost everyone is familiar with diabetes mellitus in some way. Whether we know family or friends that have been diagnosed with the condition or we’re directly impacted ourselves, diabetes mellitus has become a household name. And this is perhaps not surprising given its extremely high prevalence - nearly 9% of adults around the globe are estimated to live with the disease. But although we may know someone with diabetes, how much do we know about diabetes itself? How does it work? Why does it cause the acute symptoms and long-term complications it does? Where does an infamous scientific rivalry fit into the story of diabetes? How long have humans been dealing with this disease, and how far has treatment come since the early days of diabetes? And importantly, how has our perception and portrayal of diabetes changed over the course of its history? In this episode, we seek to answer all these questions and many more about the globally-prevalent diabetes mellitus. See omnystudio.com/listener for privacy information.

Twenty years ago this month, letters containing Bacillus anthracis spores were mailed to various politicians and news media offices in the US, resulting in illness, death, and a widespread fear that transformed anthrax from an agricultural disease or occupational hazard into a potential weapon of bioterrorism. In this episode, we explore the many dimensions of anthrax, from the different ways B. anthracis can cause disease to the incredibly long and varied history of the pathogen, a history of which bioterrorism is only a very recent part. Adding to anthrax’s multifaceted nature is the fact that B. anthracis is an environmental pathogen, one that can greatly impact livestock and wild animals, which requires collaboration across fields to effectively identify and control anthrax outbreaks. To help us explore this pathogen from a One Health perspective, we were so thrilled to chat with Dr. Johanna Salzer, Veterinary Medical Officer in the Bacterial Special Pathogens Branch at the US Centers for Disease Control and Prevention, who filled us in on the veterinary side of anthrax, and Morgan Walker, spatial epidemiologist at the University of Florida, who talked us through the environmental factors that affect B. anthracis distribution and emergence. Tune in for a much more than surface-level look at this spore-forming pathogen. See omnystudio.com/listener for privacy information.

A nighttime “kiss” from a bug that casts a curse on its recipient in the form of a lifelong, and possibly fatal, illness. No, this isn’t some half-remembered fairy tale. It’s the true story of Chagas disease, caused by the parasite Trypanosoma cruzi and transmitted by many species of triatomines (aka kissing bugs). In this episode, we take you through the utterly complicated biology of Chagas disease in its acute and chronic forms, the surprising evolutionary and historical background of this parasite and the scientist for whom it’s named, and finally the grim reality that is the global status of Chagas disease today. The dizzying ecological complexity and pathophysiological mystery of this disease makes it a challenge to study, and the lack of funding only compounds the issue; Chagas disease bears the dubious distinction of the most neglected of all the neglected tropical diseases. In spite of this, many people are dedicated to easing the global burden of Chagas disease, and we were delighted to interview two of these Chagas champions for this episode. Daisy Hernandez, Associate Professor at Miami University, joins us to discuss the inspiration for her recent book The Kissing Bug: A True Story of a Family, an Insect, and a Nation’s Neglect of a Deadly Disease, and Dr. Sarah Hamer, Associate Professor at Texas A&M University, delves into the ecological aspects of this disease and shares the incredible community science program that raises awareness about T. cruzi and the bugs that transmit it.To learn more, check out the links below:Daisy Hernandez: website, Twitter (@daisyhernandez), Instagram (@iamdazeher), Facebook Dr. Sarah Hamer: lab website, lab Twitter (@hamer_lab), Community Science Program See omnystudio.com/listener for privacy information.

While many of us know how deadly dysentery can be from playing countless hours of The Oregon Trail, there’s only so much that the classic game covered regarding this multifaceted disease. For instance, did you know that it can be caused by multiple pathogenic microbes? Or that it is and always has been closely associated with warfare and armies? Or that it remains one of the leading causes of death globally for children under five? In this episode all about dysentery, we pick up where The Oregon Trail left off. Tune in to hear facts about ancient toilets and a list of famous people killed by the disease and to learn how dysentery isn’t just about diarrhea and how the “bloody flux” lives up to its (horrible) colorful name.

Bumps and bruises. Cuts and scrapes. Gashes and gouges. Injuries small and large are familiar to all of us, but what happens when part of our body’s innate healing ability is disrupted? What happens, for instance, when the blood just won’t stop flowing? In this episode, we explore one of the most common of these disruptions: the clotting disorder known as hemophilia. From the physiological nitty gritty on how blood clotting actually works to the long history, at times both tragic and triumphant, of the “royal disease”, we trace the story of hemophilia, ending with a hopeful look towards the future.

“Let’s do Bartonella next,” we said. “It’ll be straightforward and fun,” we promised ourselves. Turns out we were half right. In this fun but not quite straightforward episode, we tackle not one, not two, but three different species of Bartonella bacteria that can cause disease in humans: Bartonella bacilliformis (Carrión’s disease), B. quintana (trench fever), B. henselae (cat scratch disease). Essentially, we’re giving you three mini-turned-maxisodes for the price of one! For each pathogen, we review its surprisingly strange biology, take a brief tour of its history, and wrap up with a look at its current status across the globe, comparing and contrasting along the way. By the end of this ride, you’ll be bursting with Bartonella trivia, in awe of dental pulp, and scratching your head about the transmission of cat scratch fever.

Celebration wasn’t the only thing in the air in Philadelphia in July of 1976. Over the course of several days during the 58th Annual Convention of the American Legion, a killer mist spewed out of the air conditioning units throughout the building and into the sidewalks nearby. The result was a large outbreak of unexplained febrile pneumonia, often fatal, that would acquire the name Legionnaires’ Disease. What was causing this terrifying disease and how could it be stopped? In this episode, we walk through the massive investigation into this outbreak that would lead to the discovery of the causative agent, Legionella pneumophila, and explore the biology of this mysterious pathogen. We wrap up the episode with a look at the current status of Legionnaires’ Disease and a potentially grim forecast for its prevalence as the world slowly gets back to normal.

Ah, chickenpox, that pesky old childhood illness. And that’s all it is, right? Just a mild, routine infection that we all used to catch until the vaccine came around? Not quite. In this episode, we learn that, when it comes to the varicella-zoster virus, not everything is as it seems. We explore the complex nature of this virus, how it can make you kinda sick and then how it can make you really, really sick. After that, we dive into the evolutionary origins of this virus and the different infections it causes (spoiler alert: shingles as a viral survival strategy?!). And finally we trace its human history from discovery to vaccine to where we stand with chickenpox and shingles today. See omnystudio.com/listener for privacy information.

When you think of mercury, what springs to mind? Is it the entrancing drop of shimmery liquid that flows from a broken thermometer, giving the metal the name quicksilver? Or is it the warnings of overconsumption of fish and bioaccumulation? Or perhaps it’s the Mad Hatter from Alice in Wonderland? The story of mercury, in both its biology as well as its history, is vast and varied, and in this episode, we attempt to piece together a picture of this heavy metal. We first delve into the pathophysiological effects of the different forms of mercury exposure on the body, and then take a narrow tour of the metal’s history, focusing primarily on Minamata disease, before wrapping it all up with a look at just how widespread mercury contamination is today. Although the relationship between humans and mercury is as old as history itself, there are still so many lessons to be learned from it, especially “what is the true cost of progress?”.

Over the past year and a half, we have learned so much about this virus, but there is still more to know. There always will be. We have seen the widespread impacts that the pandemic has had on all facets of society, but there is still more to see. There always will be. The COVID-19 pandemic is not over, and its effects will continue to be felt for years to come. What can we expect in a post-pandemic future? Frankly, no one knows. But we can make some guesses based on what we have already seen. Throughout the COVID-19 pandemic, one of our best reference points for comparison has been, of course, the deadly and devastating 1918 influenza pandemic. What can that pandemic tell us about our own uncertain future, and where do comparisons simply fall short? Did the lessons learned from the 1918 pandemic change the course of COVID-19? Or were we doomed to repeat history? To help us look forward by looking back, we are so excited to be joined by John Barry, award-winning and New York Times best-selling author of books such as The Great Influenza: The story of the deadliest pandemic in history (interview recorded May 25, 2021).This marks the tentative final episode in our Anatomy of a Pandemic series on the COVID-19 pandemic. There is still more ground to cover (there always will be), and it’s entirely possible we’ll produce additional episodes in the future, but this is it for now. Thank you to everyone who has been interviewed, who has sent in their firsthand account, and who has listened. We appreciate all of you so very much.To wrap up this episode as we always do, we discuss the top five things we learned from our expert. To help you get a better idea of the topics covered in this episode, we’ve listed the questions below: Can you remind us of some of the similarities as well as some of the differences between the COVID-19 pandemic and the 1918 influenza pandemic? The COVID-19 pandemic has been highly politicized, both in the US and elsewhere. Did we see a similar intersection of politics and public health in 1918, and if so, how did that affect both the way that pandemic played out as well as the aftermath? You wrote that the single most important thing for our society and our governments to do in this pandemic was to tell the truth. How did countries fail to tell the truth in 1918? And how would you rate our honesty during this present pandemic? How do today’s methods of science communication differ from the ways the public got their public health information back in 1918? Was there a similar issue with rampant disinformation campaigns? How did the 1918 influenza affect the public health infrastructure in the US? Did it change the general perception of the role of public health? During the 1918 pandemic did we see countries working together to try and solve the influenza crisis, or did we see intense nationalism due to the ongoing war? After the 1918 pandemic came the Roaring Twenties, with its dramatic lifestyle change and economic growth. Could you talk about what this period looked like and how much of it came as a reaction to the end of the 1918 influenza pandemic and WWI? How long did the 1918 pandemic live in our collective consciousness as a vivid reality? Given its scale and duration, do you think this pandemic will live in our collective consciousness more vividly? Can you talk about some of the limitations in applying lessons learned from the 1918 influenza pandemic to today’s reality? What are some things that you hope we keep from this pandemic, either personally or as a society? See omnystudio.com/listener for privacy information.

Every summer, when the warm weather rolls around and the local ponds and lakes heat up enough for a tempting dip, remember that there may be something else lurking in those waters besides the people looking to cool off. Naegleria fowleri, the topic of today’s episode, makes its home in warm, fresh waters, and that’s mostly where it stays, until a chance encounter between human and amoeba introduces it to a new locale: the brain. In this episode, we explore the brutal biology of the so-called ‘brain-eating amoeba’, walk through its recent but global history, and discuss the possible future of this pathogen, both good (e.g. treatments, awareness) and bad (e.g. climate change, land-use change). Even though this is a very rare disease, its deadly potential is deeply felt by those impacted by it. We are very grateful to Dr. Sandra Gompf, who shares her story of how her son Philip’s fatal encounter with Naegleria fowleri led her to create Amoeba Season, a Philip T Gompf Memorial Fund for Infectious Disease Research project. You can learn more about Dr. Gompf’s story on her website, amoeba-season.com, where you can also find many helpful links for raising awareness, fact sheets on amoebic meningitis, and a wonderful set of resources for healthcare professionals. As Dr. Gompf says, amoebic meningitis is 99% fatal but 100% preventable, and the best method of prevention is knowledge - Amoeba Season is a great place to start.

From virology to vaccines, from education to economics, and from disparities to disease, our Anatomy of a Pandemic series has covered many different aspects of the COVID-19 pandemic. With such a broad range of topics and an often birds-eye view of the situation, it can be easy to forget that this is a large-scale event happening to individual people. The impacts of the COVID-19 pandemic are widespread but also deeply personal and absolutely unique. In this episode, we wanted to take this opportunity to recognize this aspect by featuring firsthand accounts that we have received from listeners over the last several months sharing their pandemic experiences. We have no expert to feature for this episode because, by this point, we are all experts in our own COVID-19 stories. Which stories resonate with you? Which ones surprise you? Let us know! And a huge thank you again to everyone who has shared their firsthand accounts with us - we feel so honored to hear them. See omnystudio.com/listener for privacy information.

Our sign-off, “wash your hands, ya filthy animals”, has never been more appropriate than with this episode on puerperal or childbed fever, now known as maternal peripartum infections. It took us over seventy episodes to get here, but today we finally tell the tragic story of Ignác Semmelweis, the “father of hand hygiene” and “savior of mothers”, whose keen observations and devotion to his patients earned him ridicule in his time and respect in ours. But the tragedy of this episode’s topic doesn’t reside solely in the past. Today maternal peripartum infections are still a major contributor to maternal morbidity and mortality worldwide, and, surprise surprise, the impact is not equally felt across racial, ethnic, and socioeconomic groups. Join us as we dive into this historically rich, medically complicated, and still appallingly prevalent group of infections. See omnystudio.com/listener for privacy information.

The COVID-19 pandemic has touched all of our lives in incredibly varied ways, with no two experiences exactly alike. Despite this, we all probably share the same thought: how can we stop this from happening again? In this episode of our Anatomy of a Pandemic series, we ask that question in the context of wildlife conservation. Why is protecting biodiversity synonymous with protecting our own health? If spillover events themselves are inevitable, how can we limit the likelihood that they will become epidemics or pandemics? Where do commercial wildlife markets and subsistence hunting fit into the equation? To help us answer these questions and more, we are thrilled to be joined by Dr. Chris Walzer, Executive Director of Health at the Wildlife Conservation Society (interview recorded April 6, 2021). And for more information on the topics discussed, check out the WCS’s COVID-19 News and Information page and read a recent Op-Ed piece by Dr. Susan Lieberman and Dr. Christian Walzer about why biodiversity is crucial for preventing pandemics. As always, we wrap up the episode by discussing the top five things we learned from our expert. To help you get a better idea of the topics covered in this episode, we’ve listed the questions below: Now that we are over a year into this pandemic, what do we know about the sequence of events that led to this pandemic? People have been studying spillovers and the emergence of novel viruses for a long time and have been saying that a pandemic like this was inevitable. So what did we do wrong on a national or international level? What things did we do right, or what things did we adequately prepare for during this pandemic? What are the ways in which we’ve made scientific progress or the ways in which the world has fundamentally changed that have allowed this pandemic to play out differently than it could have 20 years ago? Can you talk us through some of the nuance in the interactions between commercial wildlife markets, spillover events, and wildlife hunting for subsistence purposes? How predictable are spillover events themselves? Or perhaps, how predictable are the scenarios that would increase risks for spillover and how predictable are the events that follow? Since another spillover event could happen at almost any time, what measures do we have in place to prevent these events from turning into another pandemic? Where does wildlife and forest conservation fit into this equation? Pandemic preparedness and pandemic response are two different things. How do these two aspects of dealing with a pandemic differ and who is involved in each of these efforts? What are people who study this the most concerned about when it comes to the next pandemic? What are the areas in which we still have big improvements to make in how we prepare for or predict or try to prevent pandemics based on what we’ve learned during this one? What do you hope we keep or learn from this pandemic, either personally or as a society? See omnystudio.com/listener for privacy information.

A fluffy white fungus and a little brown bat. A deafening silence and an uncertain future. In this episode, we explore one of the most devastating wildlife diseases in recent times, white-nose syndrome. Since its debut in North America in 2006, this fungal pathogen has spread across much of the continent, leaving millions of dead bats in its wake. Why is it so deadly? Which bats are at risk? Where did it come from? And most importantly, what can we do about it? We attempt to answer these questions and more about this pernicious pathogen, and we are so delighted to be joined by Dr. Winifred Frick, Chief Scientist at Bat Conservation International and Associate Research Professor at UC Santa Cruz, who helps us take a closer look at the ecology and impact of this disease on North American bat populations.

This pandemic has certainly taken its toll on all of us, but one group that has been particularly hard hit are those who have been on the front lines, continuing to take care of patients even when PPE was running low or nonexistent, even when there were no more ICU beds available. During both non-pandemic and pandemic times, physicians and other healthcare workers experience a tremendous deal of stress and pressure that can lead to depression, isolation, anxiety, moral injury, and other mental health issues. In this episode of our Anatomy of a Pandemic series, we seek to understand the factors contributing to the prevalence of these mental health issues among healthcare workers, the stigma that often prevents the seeking of treatment, the role that the COVID-19 pandemic has played in exacerbating these issues, and the ways in which the medical system has done or can do better. We are very excited to be joined by Michael Myers, MD (interview recorded March 29, 2021), psychiatrist and Professor of Clinical Psychiatry at SUNY-Downstate Health Sciences University in Brooklyn, NY and author of several books, including his latest, Becoming a Doctors’ Doctor: A Memoir.As always, we wrap up the episode by discussing the top five things we learned from our expert. To help you get a better idea of the topics covered in this episode, we’ve listed the questions below: How did you become interested in the field of physician mental health, and what made you choose to pursue it? Can you talk us through some of the challenges healthcare workers face and what impact they have on their mental health? Does this field experience things such as depression, anxiety, substance abuse, and suicide at higher rates than the general public? What does the stigma surrounding mental illness look like in the medical field and how does it contribute to the high rate of mental health issues in healthcare workers? Can you talk a bit about where these mental health issues among healthcare workers originate and how each step of medical training and beyond contributes to the problem? How much of this is a problem unique to the US and how much of it is universal? What are some of those changes you have seen throughout your thirty-five year career as a psychiatrist primarily treating other physicians? How have we gotten better, and what are the areas in which we have failed to make improvements? How do these public health crises, especially COVID-19, amplify the issues that physicians are already facing in terms of mental health? Can you talk a bit about the “healthcare heroes” narrative and how damaging it can be? What is some of the fallout you think we can expect to see in the long-term from the COVID-19 pandemic? As family members or friends or partners of healthcare workers, what are worrying signs that we can look out for? How do we recognize these signs in ourselves as well? For those who maybe have friends or partners or family members who are frontline health workers, what are some of the ways in which we can help and provide meaningful support during these times as well as in non pandemic times? What do you feel are the biggest failings of the medical system in terms of emotional and mental health support for those in medicine? How can we begin to change things? What role should medical school play? Hospitals? Other physicians? See omnystudio.com/listener for privacy information.

In this classic TPWKY episode we travel down rivers and into worm-laden nodes as we take a look at the complex world of Onchocerca volvulus, the vector-borne parasite that causes river blindness. Join us as we learn why the name ‘river blindness’ captures only one dimension of the devastation caused by this parasite, how the short evolutionary history of this worm is at once surprising and enlightening, and why grasping the disease ecology of this system has been crucial in successful control efforts. As a bonus, if you tune in, you’ll get to hear how on earth The J. Geils Band fits into this story and the integral role that dog digestion has played in the history of this parasite.

The COVID-19 pandemic has disproportionately impacted racial and ethnic minorities, especially here in the United States. Higher infection, hospitalization, and death rates due to COVID-19 have been observed for historically marginalized groups, and the harmful effects stem beyond those relating to health, with higher unemployment and food and housing insecurity also reported. Yet these disparities did not emerge anew from this current pandemic; rather, this pandemic has served to amplify existing structural inequalities in the healthcare, educational, legal, and housing systems, among others. In this episode of our Anatomy of a Pandemic series, we explore the deeply entrenched roots of racial disparities in the US, how our narrow focus on outcomes often fails to capture the complex causes of inequalities, and ways in which we can begin to work towards health equity in this country. We are so thrilled to be joined by Harriet Washington (@haw95) (interview recorded March 10, 2021), writer and medical ethicist, whose groundbreaking work on this subject through books such as Medical Apartheid, A Terrible Thing to Waste, Carte Blanche, and others has led to much-deserved critical acclaim.As always, we wrap up the episode by discussing the top five things we learned from our expert. To help you get a better idea of the topics covered in this episode, we’ve listed the questions below: Can you tell us a bit about your new book, Carte Blanche: The Erosion of Medical Consent, and what inspired you to write it? Although health disparities have been around forever, it was only within the last few decades that the term itself was coined, and it’s often only vaguely defined. Would you mind describing what we mean when we talk about health disparities? Can you talk a bit about how it’s not just being able to go to a doctor or afford a doctor, but how things like access to education, chronic stress, and environmental justice interact with and compound each other when it comes to health disparities? What are some of the different ways that we measure health disparities? Can you talk about why it is important to understand the context of these disparate outcomes? Can you talk about the disproportionate impact that COVID-19 has had on communities that were already facing significant barriers to healthcare? How has the narrative of ‘race-based medicine’ shown up in discussions of the disproportionate impact of COVID-19 on certain groups of people? How can we increase health equity in this country? What can we do at an individual level to help, and what are some policies at the state or national level that could help narrow this gap? How can the medical establishment work to earn back the trust of these communities that we have historically disenfranchised (and in many ways continue to disenfranchise) when it comes to health?

Of the many topics our podcast has covered in the past, from smallpox to scurvy, vaccines to birth control and beyond, one factor has linked nearly all of them: HeLa cells. These cells and the woman from whom they were taken have often remained behind the scenes in the coverage of these topics, but they have nevertheless been absolutely fundamental in the development of technologies, the advancement of knowledge, and the discussions of ethics, ownership, and informed consent. In this week’s episode, we want to do more than acknowledge the contribution of Henrietta Lacks and her cells to the field of biomedical science. We want to explore what it is about HeLa cells and other cell lines that makes them ‘immortal’. We want to learn what Henrietta was like as a person. We want to ask how it was possible for her cells to be taken from her without her consent or knowledge. And we want to share the tremendous impact Henrietta and her cells have made and continue to make on our world in so many ways.For more information about the Henrietta Lacks Foundation, check out the website.

We’re over a year into the COVID-19 pandemic, and our understanding of this virus and the disease it causes has grown immensely. And while we’ve learned so much about the spectrum of disease severity, the wide array of symptoms, and the effectiveness of various treatments, there is still so much we are discovering about this illness. In this installment of our Anatomy of a Pandemic series covering the COVID-19 pandemic, we review what we currently know about the disease caused by the SARS-CoV-2 virus as well as emerging questions such as what exactly is long COVID or how well do vaccines work against the new variants? To take us through this massive topic, we enlisted the help of two experts, Dr. Krutika Kuppalli (@KrutikaKuppalli), infectious diseases physician and assistant professor at the Medical University of South Carolina (also featured in Ch. 3: Control of this series), and Dr. Jason Kindrachuk (@KindrachukJason), assistant professor and Canada research chair in molecular pathogenesis and emerging viruses at the University of Manitoba (interview recorded March 16, 2021). As always, we wrap up the episode by discussing the top five things we learned from our experts. To help you get a better idea of the topics covered in this episode, we’ve listed the questions below: How much does the infectious dose, or the amount of virus a person is exposed to, play a role in whether they will get the disease and/or how severe the disease might be? How soon after being exposed does someone become infectious and how does that infectivity change over the course of infection? How much does infectiousness or viral shedding vary across disease severity? Are people who are severely infected more contagious than those who are asymptomatic? Could you walk us through the spectrum of COVID-19 in terms of symptoms or clinical observations, touching on first asymptomatic, then mild, then moderate or severe cases? What proportion of cases are severe vs mild vs asymptomatic? How much do symptoms or the general course of disease vary from person to person? How predictable is this virus? Can you talk about some of the lingering effects of infection and how frequently long COVID seems to occur? How has our estimate of the case fatality rate changed over this pandemic? Can you talk about some of the risk factors that seem to be associated with severe infections? Is there any link between blood type and risk of infection? What do we know about pregnancy and infection with COVID-19? Do risks regarding pregnancy vary depending on when during pregnancy someone may be exposed or infected? What do we know about the duration or nature of immunity and the risk of reinfection? How has treatment for COVID-19 cases changed throughout this pandemic? Are we any better at treating patients with severe cases now than we were eight or so months ago? What do we know at this point about the vaccine candidates in terms of their effectiveness against new variants that have emerged? What does it mean if these vaccines are slightly less effective against some variants than others? What do the latest studies show about vaccines preventing asymptomatic as well as symptomatic infection? What is something you hope to take away from this pandemic, either on a personal level or as a society? See omnystudio.com/listener for privacy information.

Despite being one of the earliest recognized genetic diseases, many aspects of Huntington’s disease remain shrouded in mystery. This stems in part from our limited grasp on how our own minds work but also from the dark history of Huntington’s disease and the shame and silence that accompanied it for so long. In this episode, we attempt to bring what we know about Huntington’s disease into the light, to talk frankly about the characteristics and progression of this hereditary disease, the role of eugenics in creating and promoting the stigma surrounding it, the ethical considerations surrounding genetic testing, and the medical and scientific advancements that give us reason to hope. And we are so grateful to the provider of our firsthand account for sharing their perspective on what it’s like to be diagnosed with this disease. Tune in for all this and more.

Don’t be daunted by the length of this disease name or just how difficult it looks to pronounce. By the end of the episode, you’ll be saying it right along with us, and bonus, you’ll also be armed with a whole bunch of excellent trivia about this fascinating fungal disease. In this episode, we dive right into all things coccidioidomycosis, also known as Valley fever, which also happens to be the first human fungal pathogen we’ve covered. We’ll walk you through its unusual dual natured lifecycle, its somewhat recent but surprisingly rich history, and the present threat it poses, especially in light of climate change and the United States prison system. This fungus is much more amongus than you may have suspected. We are also so lucky to be joined by Tori, who shared with us her firsthand account of contracting this fierce fungus.

The world of human papillomaviruses is vast and varied, and causing cervical cancer is just one of the many roles these viruses can take on. From their carcinogenic tendencies to their more benign wart-forming ways, this episode explores what these tiny viruses have taught us about how our bodies prevent cancer, how imaginative old timey cures for warts can be, how slow acceptance of the facts and a failure in marketing led to a delayed and impaired vaccine uptake, and so much more. You could say we’re covering all aspects of this highly-requested topic, warts and all. The historical stigma of cancer as a “woman’s disease”? Check. What’s actually inside a wart? Check. The possible origins of a mythical creature? Check. The massive disparity in vaccine access between high- and low-income countries? Check. Tune in to hear it all.

From the first skin grafts to the future of 3D printed organs, the science of organ transplantation has always seemed like something out of a sci-fi novel. How on earth can an organ from one person be removed and successfully placed into another person? Who first attempted such a monumental feat, and how long did it take for trial and error to become trial and success? Our episode this week seeks to answer these questions and so many more as we tackle the massive topic of organ transplantation. We begin by examining the immunological nitty gritty of transplant science and follow that up with the long and storied history of transplants. We round things out with a look at the numbers, which show the unfortunate reality that demand far outpaces availability, a reality that may soon be improved with innovative approaches towards bioengineering. And we are so excited to be joined by two fantastic guests, Carol Offen and Dr. Elizabeth (Betsy) Crais, who share their stories of what it’s like to donate or receive a kidney. Carol, who is a NKF Kidney Advocacy Committee member, has a great website that includes many resources where you can learn more about kidney donation as well as keep an eye out for Carol and Betsy’s book, The Greatest Gift: The Insider’s Guide to Living Kidney Donation. You can also follow Carol on Twitter (@CarolOffen) and through heradvocacy page on Facebook. We will also post additional links for where to learn more about organ donation and advocacy work on our website. See omnystudio.com/listener for privacy information.

Here’s a pop quiz for all of you: what disease makes you sweat profusely, run a slight fever, develop body aches and a pounding head and then makes you drop dead within hours of symptom onset? If you answered “I have no idea”, you passed! Because we haven’t a clue either. In this episode, we attempt to tease apart the mysterious sweating sickness, which struck only five times in the 1400s and 1500s in England, leaving in its wake terror, confusion, and a trail of bodies. Although the sweating sickness has not been seen since (or has it?), scientists and scholars continue to investigate this mysterious illness and propose various pathogens as the likely causative agent. Tune in to hear us go through the most popular explanations to see if we can form our own consensus on ‘the sweat’. See omnystudio.com/listener for privacy information.

For many of us, rubella has simply come to mean the R in MMR, the routine childhood measles, mumps, and rubella vaccine. But that hasn’t always been the case. There was once a time when the rubella virus routinely made front page news and was at the center of countless legal discussions. This week, we explore everything you’ve ever wanted to know about this virus. We start off by asking what this virus does to your body and how it can cross the placenta, leading to congenital rubella syndrome. Then we journey through the short but impactful history of this disease, from the discovery of the effects the virus can have on a developing fetus to the widespread epidemics that spurred on the development of a vaccine. Finally we wrap up with some much-needed good news about the global decline of rubella and congenital rubella syndrome. See omnystudio.com/listener for privacy information.

The fourteenth installment of our Anatomy of a Pandemic series on COVID-19 dives into what we’ve learned about SARS-CoV-2, the virus that causes COVID-19. Curious about the new strains or variants making headlines lately? Or how exactly tests for COVID-19 actually work? Or perhaps you’ve been wondering about the different routes of transmission that this virus uses. Whatever your virology question, we’ve (hopefully) got you covered. We were fortunate enough to interview virologist Dr. Angela Rasmussen, affiliate at the Georgetown Center for Global Health Science and Security, and whom you may remember from our earlier episode on the virology of SARS-CoV-2, which we released all the way back in March 2020. Dr. Rasmussen was kind enough to sit back down with us to answer all of our many burning virology questions (interview recorded December 30, 2020). As always, we wrap up the episode by discussing the top five things we learned from our expert. If you would like to read Dr. Rasmussen's article in The Guardian about the new SARS-CoV-2 variants, follow this link.To help you get a better idea of the topics covered in this episode, we’ve listed the questions below: Can you tell us a bit about SARS-CoV-2? What kind of virus it is, other viruses it’s related to, and what that tells us about the virus and the disease it causes? Could you tell us a bit more about the B117 strain, like whether this appears to be a new strain and how it is different? Do we have any evidence of any strains that seem to cause more severe disease or affect different populations? Where do these new strains come from? What does this new strain (or multiple new strains) mean for the effectiveness of the vaccines that have been developed? Will these vaccines work against these new strains? What additional things have we learned about the structure or surface proteins of SARS-CoV-2 that give us more insight into how it causes disease or the widespread effects it has on the body? Is there any indication that the virus can be airborne? Does fecal-oral transmission seem to be playing a role? What are the various ways to test for SARS-CoV-2? Can you walk us through what each experience is like? How do the rapid vs PCR tests work? And can you compare their accuracy? Why does the rapid test have a higher rate of false negatives than the PCR test? What has this pandemic taught us about virology? See omnystudio.com/listener for privacy information.
