Roman Mars
This is 99% invisible. I'm Roman Mars. You may know John green as a YouTuber, a podcaster, or a mega bestselling young adult novelist, but John's writing goes way beyond novels. His latest book is a nonfiction deep dive into one of the oldest and deadliest threats to humank.
John Green
You know, if you told me six years ago that my next book would be about tuberculosis, I would have been duly surprised. I did not think of tuberculosis as being really much of anything. I thought it was a disease of the past, like a disease that killed the guy in Red Dead Redemption 2. Not a present tense phenomenon.
Roman Mars
Tuberculosis is in fact, the single most lethal infectious disease in the history of the world. It's been infecting and killing humans for millennia. But what makes the story of TB so maddening, and what drew John to the topic is that the disease is still killing over a million people a year, despite the fact that we already have a cure. John's book is called Everything Is Tuberculosis and in it he describes how foreign policy and corporate greed make TB so hard to eliminate. He also explains the history of tuberculosis and all the unexpected and fearful, fascinating ways TB has shaped our world. I really love this book. It is both heartbreaking and triumphant. It is full of fun facts and sober realities. And I really just want to have John on the show to talk about all the stuff he learned while writing it. So let's start at the very basics I realized when I was reading this I didn't have a full grasp of what tuberculosis actually was. So could you tell me about it as a sort of biological entity? What it does to you? How does it spread?
John Green
Yeah, so it's a bacterial illness, but it's a weird bacteria. It's a bacteria with a really thick cell wall that takes a long time to make and so relative to other bacteria, it grows very slowly. Like I think in a lab environment, it doubles every day, whereas something like E. Coli will double every 20 minutes.
Roman Mars
Wow.
John Green
So it's an unusual bacteria, but it also that thick cell wall makes it hard for infection fighting cells to penetrate. And so usually what actually happens is that a bunch of white blood cells will surround some bacteria and kind of wall it off in what's called a tubercle, which is why we have the word tuberculosis. I think it's technically pronounced tubercle, but I don't like pronouncing it that way. It seems wrong.
Roman Mars
But this weirdness is one of the reasons why it's kind of both persisted and sort of inveigled its way into culture over thousands and thousands of years. And it really fascinated by this. And I'm also fascinated by the idea of, like, how it was, you know, before people knew of it as a bacteria, how it was conceptualized. Can you talk about some of the things that you found about how, you know, ancient civilizations treated this odd bacterium?
John Green
Sure. So we've had tuberculosis or diseases very similar to it for all, probably all of human history and even further back in the story of people, back to Homo erectus. And so we've had a long time to imagine tuberculosis, and over the years we've imagined it lots of different ways. Some people saw it as a contagious illness from the beginning. In ancient China and ancient India, it was often seen as contagious. Some people saw it as an inherited illness. Especially in northern Europe and the United States, it was seen as a genetic disease that was associated with certain personality traits. If we go all the way back, we don't know that much about how we saw tuberculosis, but we know that it's probably responsible for around 1 in 7 of all human deaths. Of the 120 billion people who've ever lived, about 1 in 7 have died of TB.
Roman Mars
And this is like by far the. The championship killer of humans, correct?
John Green
Yeah, yeah. It's winning the all time race in terms of infectious diseases, but it's also winning the current race, which is especially discouraging because this year TB will be our deadliest infectious disease, just as it has been for most of human history.
Roman Mars
Yeah. So tell me about that period of time where tuberculosis was actually called consumption, when it was perceived as a genetic malady, a poetic and romantic malady. Could you tell me about that? Because the real symptoms of tuberculosis, coughing up blood, extreme weight loss. Those don't sound beautiful or poetic. Yeah.
John Green
So tuberculosis has always been a Highly stigmatized disease, like any disease that's seen as very serious and threatening. But at the height of what one person called the frightful tuberculization of humanity, at the height of the Industrial Revolution, tuberculosis was killing about a third of all people. It was killing rich people, poor people. Charles Dickens called it the disease that wealth never warded off. It was a disease that could strike anyone anywhere. And so we couldn't stigmatize it away. We couldn't say, well, this is just a disease of the poor, or just a disease of drunk people, or just a disease of this marginalized group or that vulnerable group, because it was a disease of everyone. And so for a period of about 150 years, especially in northern Europe, it was also a hugely romanticized disease. And consumption was widely seen as an inherited disease. And it was a disease that made you literally more beautiful, made your skin pale and your cheeks rosy and your eyes wide, like. Even as her sister was dying of tuberculosis, Charlotte Bronte wrote, consumption, I am aware, is a flattering malady. And it was also seen as a disease that made you into a genius. That, like, I remember Percy Shelley wrote John Keats when Keats was dying and said, well, you know, this. Consumption is a disease that tends to strike people who write good verses, as you have done, you know, which was I. Which I find especially interesting because Shelley knew that he also had consumption. So in some ways, Shelley was like, you know, who else is good?
Roman Mars
Me. Okay, so in the US And Europe, consumption made you this beautiful genius. But then there was a shift from that thinking to seeing it as more of an infectious disease experienced by people who are not privileged. And that shift happens starting in the late 1800s when. When scientists discover that tuberculosis is actually a bacteria.
John Green
Yeah, almost like a light switch. Very few things in history are like a light switch. And I'm exaggerating when I say it's like a light switch. It was really like a decade, but that's relatively short. You know, I often have people say to me, I wasn't aware that consumption and tuberculosis were the same disease. And I tell them, that totally makes sense, because the way consumption was imagined culturally as this ennobling disease that made you beautiful, it made you sensitive, it made you. Right. Beautiful. Poetry is completely different from the way we imagine tuberculosis today. And those are all cultural constructs. But of course, that profoundly shapes not just how people live with the disease, but also who lives with it and who dies of it. And so once we understood that TB was infectious, we started to immediately, or almost immediately See it as a disease of poverty, of crowded working and living conditions, of the cities that were called these tubercular factories of urbanity or whatever.
Roman Mars
Right. And so once people in the US and Europe figure out that TB is contagious, that leads to this sudden fixation on cleanliness. Can you tell us more about that?
John Green
Oh, yeah. An obsession with hygiene. I mean, I think I republish in the book a poster that said, you know, do not kiss babies. Your kiss of affection brings the risk of infection. And that was a big thing. Don't kiss babies, which is, you know, if you've ever had a baby, you want to just gobble them up. Ye. But also, clean shaves became very popular because there was this so called revolt against the whisker, as people believed that there must be untold number of bacteria crawling in those whiskers. Little did we know, of course, that half of all human cells are in fact microbial that don't even belong to us.
Roman Mars
Okay, so this is kind of the part of the story, you know, when people have some purchase as to what causes TB and how it spreads, that I feel like the Everything Is Tuberculosis part of your book Everything is Tuberculosis comes about. We're talking the very late 1800s, early 1900s, and we start to see the disease influencing the built world and design. So can you tell me some of the various ways in which everything is tuberculosis?
John Green
Yeah, I mean, tuberculosis shaped history, just as history shapes tuberculosis. And so everything from the Adirondack chair, which was invented to give people living with TB a chance to sit at a very specific position so they could ostensibly get more oxygen into their lungs, to the great state of New Mexico. New Mexico had all the institutions needed for statehood and was seeking statehood. And the US Congress turned them down again and again because so many people in New Mexico did not speak English as their first language or were indigenous people. And the US just didn't want to include a state like that, to be frank, because of racism.
Roman Mars
Yeah.
John Green
And so people in New Mexico were like, man, we gotta recruit some white people if we're gonna become a state. And the way they did that was by reaching out in cities to people who were living with consumption or tuberculosis and saying to them, hey, come to New Mexico. Big skies, clean air, dry air. You can dry out those wet lungs of yours. And it worked. You know, it was a big part of the reason why. Not the only reason, obviously, but a big part of the reason why Congress finally relented and brought New Mexico into the Union. And by the time New Mexico did become a State. Over 10% of all people in the state were people living with tuberculosis.
Roman Mars
And one of my favorite things from this part of the book is the story about tuberculosis and cowboy hats.
John Green
Yeah, cowboy hats definitely wouldn't exist, or at least not as we have them today, because John B. Stetson was a hat maker living in New Jersey when he got sick with tuberculosis and was told to go west. And when he went west, he eventually recovered. We don't know why. About 25% of people will eventually recover from their active disease and go on to live long, healthy lives, but some do. We've never understood that and still don't fully, but John B. Stetson was one of those who recovered. And when he recovered, the first thing he thought was, I think I can improve these hats. And that's how he came up with the Stetson hat.
Roman Mars
Because heretofore, what were hats like in the West?
John Green
So they had like, they had coonskin caps in the west, which were literally bug infested. Right. Like disgusting. And then they had straw hats that were brought up from people who lived in Mexico or Texas, which worked great except when it rained, when they weren't particularly waterproof. And so John B. Stetson was like, oh, I can solve this problem easy. I'm literally a hat maker. I know how to do this. Okay.
Roman Mars
So another invention that you write about that's related to TB is the sanatorium, which is a type of building that we don't see built or used anymore, but was a huge part of society during the late 1800s. Can you talk about the sanatorium boom in Europe and the us?
John Green
I mean, nowadays, these sanatoria. I don't know if this is your relationship with them, but they're primarily like urban exploring spaces.
Roman Mars
Exactly. Yeah.
John Green
You know, like they're mostly sort of abandoned buildings in the middle of weird places that 27 year olds go to feel alive.
Roman Mars
That's right.
John Green
But at the height of the sanatorium craze, there were almost as many hospital beds in the United States in sanatoria as there were in all hospitals combined. These huge buildings where people living with TB would be sent or would go in order to try to recover their health. These places were often in rural places or in mountain air was one way that people tried to respond to tb. Dry air was another way. Like California advertised itself as the land of new lungs to try to encourage people. I think almost as many people went to California seeking treatment for TB as went to California during the gold rush, actually. So it Was quite a movement of people all around.
Roman Mars
And all they're doing inside the sanatoria is just sequestering people to rest with their tuberculosis. It's not really a treatment center.
John Green
No, it was a rest center. So they would call it curing, and you would have to cure for eight or ten hours a day. And when you were curing, you'd often be outside trying to take in the sunshine, but you couldn't move. You were discouraged from talking. In many cases, you were discouraged from having visitors because that could excite your nervous system, which was seen as worsening tb. And so it was a really highly, highly controlled life.
Roman Mars
So let's talk about the cure for tuberculosis. At what point did people figure out how to fight it rather than just live with it?
John Green
We didn't have a cure until the 1940s when the first antibiotics were synthesized. And that was just a game changer for tuberculosis. I mean, when my great uncle died of TB in 1930, his name was Stokes Goodrich, and when he died of tb, there was just nothing that could be done. They put him in a sanatorium, he had the best care that money could buy, and he died anyway. And that was the story over and over again. But once we started developing antibiotics in the 1940s, and then eventually, by the early 1950s, realized that we could use these antibiotics in concert with each other as a kind of cocktail, that we could not only treat the disease and have it retreat, but we could cure it. And in that moment, you know, hundreds of thousands of people who were living in sanatoria were suddenly able to go home, live their lives. It was an utter miracle, a scientific miracle of the highest order. And between 1945 and 1965, we developed seven or eight different classes of antibiotics that can fight TB. It was this hugely successful period in the fight against the disease.
Roman Mars
In the 70 years since we found a cure, tuberculosis has been effectively wiped out in western countries thanks to a combination of prevention, widespread TB testing, and powerful antibiotics. But throughout the global south, not only has TB persisted, it is thriving. After the break, we'll talk about how a disease with a cure can still be killing millions of people and what the future of TB might hold.

John Green
We are back with.
Roman Mars
John Green talking about his new book, Everything is the History and Persistence of Our Deadliest Infection. So you read about how even though TB has been deadly for so long and still is, we have developed some very effective ways for preventing TB and surviving the infection. So can you talk about that?
John Green
So there's just the functional advance of the drugs themselves, but there's also advances in terms of how we distribute that stuff. So in the 25 years since I graduated from college, TB deaths have dropped by about 50%. And a lot of that's due to investment, especially by the US Government. The US Government has long been the leading funder of TB research and also TB response overall. Also other governments stepping up have played an important role in places from Sierra Leone to the Philippines. So that's the key to distributing this stuff at scale. But there's also been other major innovations in terms of our ability to detect TB earlier and then also to offer preventative care. So we can offer a shorter course of antibiotics to somebody who's been exposed to TB to make sure they never get sick. And that can be a very effective way of stopping chains of transmission.
Roman Mars
Yeah. Another key component to tuberculosis because the way it sort of functions, you know, biologically, is like detection is almost as important as the drugs to treat it. Can you talk about the role of detection when it comes to tuberculosis?
John Green
Yeah, detection is super, super important. We've got to. It helps to detect the disease earlier because then you don't have permanent lung damage. And we have these wonderful tools that we've had for a long time called chest X rays, where you can tell pretty quickly if someone has tuberculosis. We also have now, over the last 10 or 15 years, developed these incredible molecular tests that in about two hours can tell you not just if someone has TB, but which antibiotics their TB will respond to. Total game changers. Unfortunately, they're, they're really expensive. I was in a lab once in Sierra Leone and I saw their gene expert machine. And I said, oh, you have a gene expert machine? That's so cool. And he was like, yeah, if only we could afford the tests.
Roman Mars
Oh, my God. Well, what really Struck me when I was reading your book is that there's a real contrast between the west and the rest of the world. 1.25 million people still die of TB every year, mostly in the Global South. And that number is insane to me because this is a disease that we cured. So why is TB still a problem for so much of the world?
John Green
Right, so there's a lot that goes into this question. TB is a curable disease, but it's not easy to cure. Like, when we think about antibiotic related bacterial infections, a lot of times we're thinking about like a strep infection in our throats or that kind of thing, which can be treated with seven to 10 days of antibiotics. TB requires at least four months of daily antibiotics taken in a very specific cocktail, often six months, sometimes longer. And it is onerous because we still often use a strategy called directly observed therapy, where you have to be seen by someone who isn't in your family taking your medication each day. And if for some reason you couldn't get to the clinic, if you were too sick, if you couldn't afford transportation, whatever that is, then you wouldn't be able to access your medication and you could experience an interruption in treatment.
Roman Mars
Right. And you actually talk about one patient that you met at a TB hospital in Sierra Leone, and you get into how his story shows exactly how incredibly expensive and hard it can be to access good treatment. So tell me about meeting Henry.
John Green
Yeah. So in 2019, my wife Sarah and I were visiting Sierra Leone with Partners in Health to learn about the maternal healthcare system there, which Sarah and I have been working on with PIH on strengthening with the government for a long time. And on the last day of our trip, a couple of the doctors we were traveling with asked if we could visit the TB hospital. And when I got there, I opened the car door and this kid was right there. And he just physically grabbed me by the T shirt and started walking me around the hospital. And I learned that his name was Henry, and that's also my son's name. And he looked about the same age as my son. And I just, I was immediately taken with this kid. He was so charming and charismatic, and he. And he took me to the lab, he took me to the wards. I was astonished by how sick people were. I had never, you know, I've worked in hospitals and, and stuff, but I'd never. I'd never seen that many people that sick in one place before. And he took me to the kitchen where the food was made, and then eventually we made our way back to the doctors and they kind of shooed him away. And I said, who, Whose kid is that? Is that one of Yalls kids? And they said, no, that's one of the patients we're really concerned about actually. And it turns out that Henry wasn't nine like my son was. He was 17. His body had just been stunted by malnutrition and then by tb. And I mean, Henry probably first got sick when he was 5 or 6 with TB and he started to get treatment, but then that treatment was interrupted, which happens sometimes. And when that happens, you have a much higher chance of developing drug resistant tb. And that's what happened to Henry. He developed a strain of tuberculosis that was resistant to our first line antibiotics. And when I met him he seemed to be in good health. But the doctors already knew that the second line antibiotics were failing, that they'd succeeded in pushing back the disease. But now the disease was beginning to roar back when those second line antibiotics fail. It was called the injectable regimens. When those injectables fail, you know, I had one doctor tell me that's when you put the stethoscope down, that there's just not much you can do. And you know, that is the case for the vast majority of people who are like Henry.
Roman Mars
Yeah, it's really heartbreaking. One of the other obstacles that countries run into is the exorbitant cost of care. Like the GeneXpert TB testing machine that you talked about, which costs about $25 to test one person. That's more than half of what Sierra Leone spends on healthcare per person each year. And then there's the greed of the pharmaceutical companies which can charge whatever they want to for life saving drugs. But you also say that there's been some successful pushback against that.
John Green
Yeah. So between 1966 and 2012 we didn't develop any new drugs to treat tuberculosis, which was a real catastrophe. But then in 2012 we did develop some new ones. The most important of which is probably bedaquilin, which is a drug that was the research and trials for were funded primarily by public money, primarily by the US government. But the patent is actually owned by Johnson and Johnson, a pharmaceutical company. And when their patent expired, they tried to file a secondary patent, not on the drug itself, but on a compound that makes the drug more effective. And TB activists in India very smartly went to court and said, look, this is not real innovation. This is just a company trying to extend its patent forever. And after they extend their patent because of this compound, they'll find another compound to extend the patent for, and we'll never get this drug's price down. And price is a huge barrier. I mean, a huge, huge barrier. This is why people are dying is because of price. I mean, getting the drugs where they need to be is a challenge, but price is the biggest barrier. And the Indian court was like, yeah, there's no real innovation in this compound. This is just an attempt to evergreen a patent. And so in India, it became possible to get generic bodaquilin. But in almost all of the world, there was still these secondary patents stopping generic production. And lots of people came together and pressured Johnson and Johnson to abandon their secondary patents, which to their credit, they eventually did completely. So that now the price of Benaquin in just two years has gone down by over 60%.
Roman Mars
So we are living in a particularly devastating moment right now for tackling tb. Since January, the Trump administration has cut USAID and pulled the US out of the World Health Organization. We've eviscerated international aid programs that funded treatment for tuberculosis. And there's also looming threats to drug research. And even here in the US where we'd almost eliminated tb, we've been seeing cases rise in the last several years.
John Green
Yeah.
Roman Mars
And as someone who's been looking closely at the history of tb, I'm curious how this moment is landing for you.
John Green
Yeah, I mean, you know, not to put too fine a point on it, but I would like to live in a world where whatever the deadliest infectious disease is, is one we don't know how to cure. Right. Because at least then it's a technology problem, not a culture problem, not a failure of human built systems, not a failure of extractive capitalism. It's just that we don't have something figured out yet with tb. We have it figured out. We know what to do. We've done it before. And then almost all at once, there's been this absolute devastation of watching us walk away from that progress and not just. And the real problem is that you don't just walk away from progress, you embrace regression. That's what we're doing right now. We're embracing an actively worse world.
Roman Mars
And how do you see these cuts hitting people in the world with tb?
John Green
It's just devastating. I mean, we're gonna see the number of people who die from TB go up. Every single person right now who's had their treatment interrupted, and we don't even know how many people that is, but it's tens of thousands, hundreds of thousands. Every single one of Those people, even if they get back on medication in the next few weeks, it's likely that in many of those cases that medication won't work anymore because the bacteria will have had an opportunity to evolve resistance. And to have done that so chaotically, so suddenly, without any warning across the board, with an ax rather than a scalpel. I don't know how to express the devastation I feel. I mean, I don't feel hopeless, I don't feel despair, I refuse to feel hopeless. But it's been a long time since I was this discouraged.
Roman Mars
What are some of the things that have happened specifically that you've seen? Sort of like what has been shut and changed, what sort of protocols have been altered? What is it that is causing this regression?
John Green
So almost immediately there were stop work orders issued related to almost all TB response, HIV response, malaria response. But the word was that there were exceptions for life saving medication. That's what everyone was told. Now, functionally, as far as I could tell, and I have a lot of friends in this space and I work with a lot of people, very little money was actually moving, if any. And so you can say that life saving medication is flowing, but it wasn't. Instead, you know, I would get pictures from friends of, of warehouses full of TB medication just rotting in the warehouse for want of a continued work order. And then more recently, all or almost all TB response was just cut completely, just, just ended. And that's the case for malaria response as well, for a huge percentage of our HIV response. And, and it's just devastating. So many people are going to die.
Roman Mars
Just like you. I am incredibly discouraged by this moment. It feels like an unimaginable amount of cruelty to allow this stuff to happen. And I don't want to put you in a position where you have to provide us with hope, but could you share anything that you're feeling in terms of what could be done? What would put us on the right path?
John Green
Yeah, I mean, the nature of being a person is that you feel like today is the last day of human history. Right. Because it's the last day of human history you've lived through. It feels like the end of the story. Like there was a. You know, I started out zero and then I ended up 47. And that's the story of my life. Right. But of course that's not the story of my life. Hopefully, hopefully this isn't the last day. This is not the end of. It feels like the end of the story because it's the last bit I've lived through. But it's the middle of the story. And so that's why we have to fight and scrap and continue to be hopeful because it's the middle of the story. And I really believe that the end of the story for tuberculosis is the end of tuberculosis, this disease that has been with us for the whole 300,000 years that we've been here. How amazing would it be to be able to live in a world where that's no longer a public health threat? Well, we can live in that world, and right now we're taking steps away from living in that world. But those aren't the last steps we're ever going to take.
Roman Mars
John, I've had such a great time talking with you. I really loved it and I love the book so much.
John Green
Thank you for having me. Thank you for offering to read the book and for just being such a kind soul in the world right now.

99% Invisible: Everything Is Tuberculosis – Episode Summary
Release Date: April 8, 2025
Host: Roman Mars
Guest: John Green
In the episode titled "Everything Is Tuberculosis," Roman Mars engages in a profound conversation with John Green, renowned YouTuber, podcaster, and bestselling author. They delve into the intricate history, persistent challenges, and profound impact of tuberculosis (TB) on human society. John Green introduces his latest nonfiction work, Everything Is Tuberculosis, which explores why TB continues to claim over a million lives annually despite the existence of effective treatments.
Roman Mars opens the discussion by seeking a foundational understanding of TB from John Green.
John Green (02:26):
"Yeah, so it's a bacterial illness, but it's a weird bacteria. It's a bacteria with a really thick cell wall that takes a long time to make and so relative to other bacteria, it grows very slowly."
Green explains that TB is caused by a slow-growing bacterium with a resilient cell wall, making it difficult for the immune system to combat. This biological complexity has allowed TB to persist and adapt over millennia.
The conversation shifts to the historical and cultural interpretations of TB, particularly its romanticization in the 19th century.
John Green (05:16):
"Charlotte Bronte wrote, consumption, I am aware, is a flattering malady. And it was also seen as a disease that made you into a genius."
During the Industrial Revolution, TB, often referred to as "consumption," was paradoxically romanticized despite its deadly nature. Literary figures like Charlotte Bronte and poets like Percy Shelley portrayed TB as a condition that enhanced beauty and creativity, attributing it to noble traits.
Roman Mars and John Green discuss the architectural and societal responses to TB before the advent of antibiotics, highlighting the rise of sanatoriums.
John Green (12:15):
"At the height of the sanatorium craze, there were almost as many hospital beds in the United States in sanatoria as there were in all hospitals combined."
Sanatoriums became widespread, serving as controlled environments where TB patients could rest and receive what little treatment was available. These institutions were often located in rural or mountainous regions, believed to provide the dry air beneficial for TB patients.
The introduction of antibiotics in the 1940s marked a turning point in the fight against TB.
John Green (13:58):
"When we started developing antibiotics in the 1940s... we could not only treat the disease and have it retreat, but we could cure it."
Antibiotics transformed TB from a fatal disease to a manageable condition in Western countries. The development of antibiotic cocktails in the 1950s led to a significant decline in TB mortality rates, allowing many to leave the sanatoriums and resume normal lives.
Despite advancements in the West, TB remains a critical issue in the Global South due to various systemic challenges.
John Green (18:46):
"That's why people are dying is because of price. I mean, getting the drugs where they need to be is a challenge, but price is the biggest barrier."
Access to affordable medication and proper healthcare infrastructure remains limited in many developing countries. High costs of diagnostic tools like the GeneXpert machine and life-saving drugs hinder effective TB management, leading to ongoing high mortality rates.
John Green shares a poignant encounter with Henry, a TB patient in Sierra Leone, illustrating the human toll of inadequate TB treatment.
John Green (20:15):
"Henry probably first got sick when he was 5 or 6 with TB and he started to get treatment, but then that treatment was interrupted... he developed a strain of tuberculosis that was resistant to our first line antibiotics."
Henry's story underscores the devastating consequences of interrupted treatment, which can lead to drug-resistant TB strains, leaving patients with few remaining treatment options.
The discussion highlights recent policy shifts and their detrimental effects on global TB efforts.
John Green (24:40):
"Between 1966 and 2012 we didn't develop any new drugs to treat tuberculosis, which was a real catastrophe."
Policy changes, such as cuts to international aid and funding for TB research, have severely hampered progress. Additionally, pharmaceutical companies' patent manipulations have kept drug prices prohibitively high, limiting access to essential treatments.
Despite the bleak outlook caused by recent setbacks, John Green remains cautiously optimistic about eradicating TB.
John Green (28:36):
"I really believe that the end of the story for tuberculosis is the end of tuberculosis... we can live in that world, and right now we're taking steps away from living in that world."
Green emphasizes the importance of sustained effort, innovation, and global cooperation to overcome the cultural and systemic barriers that allow TB to persist. He calls for renewed commitment to TB eradication, highlighting it as a battle that humanity has the knowledge and tools to win.
