Chapter 18 Summary: “Superbug”

Content Warning: This section of the guide includes discussion of illness and death.


Green discusses the concept of a “superbug,” a strain of illness that evolves to resist all currently available antibiotics. Although the concept is alarmist in nature, it helps compel rich communities into acting against diseases like TB.


Green argues that the superbug scare isn’t necessary to compel action. For people in poor countries, the superbug is already a reality as it continues to spread untreated. At the same time, the recent COVID-19 pandemic showed that it is possible for wealthy communities to quickly invest in prevention and treatment.


This once again implies that investment in TB research is a matter of cost-effectiveness. When rifamycin was invented in the 1960s, it was considered too expensive to produce at a massive scale. Over time, the cost to produce rifamycin dramatically lowered, yet manufacturers continue to work according to the cost standards of the 1960s. This lengthens treatment and risks resistance to rifamycin, a vital cure for TB.


Green challenges the scarcity mentality by comparing Henry’s situation to that of Green’s brother, Hank, who received treatment for lymphoma in the United States. While the cost of cancer treatment in the US is extremely high, it is still made available through insurance, private systems, or public pressure, showing that high treatment cost alone does not necessarily prevent access in wealthy countries. Green questions why TB treatment, which is comparatively cheaper, is routinely withheld in low-income nations on the grounds of cost. The discrepancy, he argues, reveals a deeper injustice: Accessibility often depends not on feasibility but on who is suffering.

Chapter 19 Summary: “Vicious Cycles”

During the 1980s, active TB was commonly observed among patients who also had HIV/AIDS since the latter disease affected the immune system’s capacity to resist TB growth. This rapidly drove a crisis of death across the Global South, in which TB was killing patients faster than doctors could anticipate. Despite the crisis, little was done to bolster TB treatment in the countries that were most affected by a lack of access to healthcare resources. Instead, investment was placed solely in HIV treatment research, which made the disease survivable in Global North nations. Meanwhile, life expectancy dropped in countries like Lesotho because of the lack of access to effective TB and HIV treatments.


The Global North explains this lack of access away as the fault of the Global South nations, which failed to develop their infrastructure and healthcare systems to operate according to Global North standards. This only proves that racism persists in the field of public health, even though the Global North’s claims have no basis in reality. By the mid-2000s, public programs would finally give poor countries access to effective HIV treatment. Furthermore, these programs enabled the development of transportation systems, which aided the dispersal of treatment. These solutions came too late, however, for the millions of people who died in the 20-year period between the start of the crisis and the date that treatment became more accessible.


Green argues that TB is above all “a disease of vicious cycles” (159), exacerbating poverty, healthcare, nutrition, and stigmatization. TB amplifies the injustice of inequitable access.

Chapter 20 Summary: “Hail Mary”

Henry’s experimental treatment, a cocktail of drugs devised around his comorbidities, was finally secured through the financial aid of Partners in Health, a nonprofit partner that supported Lakka. The success of the drug would allow Henry to become a case study for greater access to drugs that treat drug-resistant TB. While waiting, Henry wrote poems, including one titled “Golden Axe,” about warriors trying to find refuge in battle.


Green summarizes his discussion thus far by stating that Henry’s TB was the result of historical and systemic choices to let TB spread across Sierra Leone. Henry responded to those social forces by making a choice of his home: to stay at Lakka and trust in the struggling healthcare system.


Henry’s treatment arrived at Lakka in a piecemeal fashion. Dr. Girum began the treatment at once, though no one was sure if it would make him better.

Chapter 21 Summary: “Like Magic”

Though his symptoms improved over the next week, Henry remained cautious of the treatment’s success. This was underscored by the enforced isolation he endured during treatment. One month later, Henry was walking again and gaining weight. Several months later, the bacteria were absent from Henry’s sputum. Henry’s parents were authorized to visit him again when he was much less infectious. Henry’s father apologized to Dr. Girum, to which he responded that he would have done the same in his position.


Henry finally went home after his new treatment showed steady signs of improvement. He would continue treatment for the next year, but his return home marked the happiest moment of Isatu’s life.


As they started to overcome their experience with TB, Henry and Isatu began to face their next challenge—impoverishment. Isatu told Henry that this challenge was a “constraint,” but what mattered to her was seeing him alive.

Chapter 22 Summary: “Virtuous Cycles”

Against the cynicism of vicious cycles, Green observes that Henry survived TB because of the existence of virtuous cycles. This manifestation of Henry’s virtuous cycle will go on to save more lives in the future.


Green narrates another virtuous cycle that transpired in Peru in the 1990s. With no national TB program in place, activists pushed the government to implement DOTS in the country. According to the World Health Organization, however, DOTS guidelines provided no special treatment for patients who had drug-resistant TB because it was not cost-effective. Working against the increasing spread of drug-resistant TB, Partners in Health began to operate in Lima, where they offered personalized treatments and support to step in where the government had failed. They did this in the hope of proving the feasible treatment of multiple drug-resistant TB in poor countries, thus kicking off a virtuous cycle. By 1998, a large majority of their patients were cured, driving reforms in the World Health Organization’s DOTS guidelines. When it was discovered that the patents on multiple drug-resistant TB treatments had expired, Partners in Health initiated the development of generic drugs that would make the treatment vastly more accessible.


Green also shares the story of Phumeza Tisile, a South African woman whose initial diagnosis of TB had been missed by microscopy tests. When she was correctly diagnosed with TB, the illness was already advanced enough to resist the impact of antibiotics. During the three years of her treatment, which was influenced by Partners in Health’s work in Peru, Phumeza lost her hearing in both ears but was finally cured and received a cochlear implant. Because of her experience, Phumeza became an advocate for TB patients, protesting Johnson & Johnson’s efforts to extend their patent over bedaquiline in India. Her complaint succeeded, and bedaquiline became more accessible in India. Further protests by other activists and health groups ensured that the drug also became accessible in other low-income countries. The work that Partners in Health did in Peru eventually led to millions of recoveries due to greater access to bedaquiline.


There remains a challenge to make other treatments for drug-resistant TB accessible since the companies holding their patents refuse to look outside their scarcity and profit-motive mentality. Green calls for systemic reforms that help reframe healthcare not as a market-oriented industry but as a basic human priority.


The virtuous cycle doesn’t just enable one to recover from TB: It frees them up to pursue the opportunities that TB hindered them from reaching, such as education and work. Henry, for instance, went on to continue his schooling. He was eventually accepted to the University of Sierra Leone to study human resources. Henry and Isatu now live in a small new house that they were able to secure with the help of crowdfunding. Isatu likewise revitalized her reselling business with the surplus from their crowdfunding campaign.


Henry also went on to start a YouTube channel, where he could share stories of his life and show his perspective of Freetown. He uses the profits from his channel to raise funds for different causes, including improved water utilities and healthcare. He frequently shares videos of Lakka to raise awareness around the hospital’s efforts to treat TB. This awareness campaign extends to sharing his experience as a survivor of TB. Green regularly speaks with Henry, who has become friends with Green’s son, Henry.

Chapter 23 Summary: “The Cause and the Cure”

Green urges the reader to view illness and healthcare not just as a biomedical issue but as a sociological one, too. The causes of illness should always be seen as interdependent with the social factors that determine health, from food supply to equitable access to goods and services. Without those determinants, patients are disincentivized to complete treatment. Green shares his own experience of availing of a treatment for a small injury at home. He traces the various systems required to make that treatment as accessible and convenient as possible, from the electrical utilities that would help him maintain the efficacy of his treatment to the educational system that would ensure the skills competency of the healthcare workers administering the treatment.


Green points out that this luxury is not universally available. If it were, TB death would become a historical fact instead of a present reality. Green calls for systemic reforms that include the impoverished in receiving essential treatments against common illnesses like TB. These reforms also include improving the social determinants of health, comprehensively improving the quality of life so that healthcare is both accessible and convenient. By excluding the impoverished and restricting access to effective treatment, humanity itself becomes the reason why TB remains the deadliest and most common disease in the world.


Green recommends a comprehensive plan developed by anti-TB advocates called “search, treat, prevent” (STP). This plan not only treats patients infected with TB but also ensures that the chain of transmission is cut before the illness spreads further. It also saves money in the long run by reducing the need for continued expenditures as TB is eliminated. The alternative is to let TB go on as one of the world’s most prolific killers, giving rise to the long-feared superbug. Ultimately, Green calls on the reader to act toward addressing the social determinants of health so that humanity becomes the cure for TB, instead of the cause.

Postscript Summary

Green discusses the way that his obsession with tuberculosis has affected his work as a writer. His early success in young adult fiction gave him a massive platform to share his interests with the world. He is also cautious of the ways that his use of that platform can unintentionally harm others, which has made him more careful about using it over the years. Discussing the TB crisis on that platform has helped his access to that platform feel more useful. It has also helped him become more aware of the landscape of the TB crisis as it develops. He shares some examples of developments, like the creation of a mobile app called TB Hunters that helps implement the STP plan in Lesotho.


On the other hand, TB researchers are starting to see an increasing resistance to bedaquiline in new strains of TB. This increases the risk of TB all over the world, even as bedaquiline still remains out of reach for millions of people.


Green proposes a way to fathom the 1,250,000 people who die each year from curable diseases. He reminds the reader of Henry and how his life has gone on post-recovery. Henry’s deft use of social media has earned him recognition at his university. Green also shares a link to Henry’s YouTube profile. Green urges the reader to see the shared humanity between themselves and Henry and to relate their experience of life to that of Henry’s. He asks the reader to multiply that by 1,250,000 and then urges them to help in the fight against diseases of injustice.

Chapter 18-Postscript Analysis

In this final section, Green discusses the concept of the “superbug” to remind the reader what is at stake for all the people involved in the story, from Henry to the nation of Sierra Leone. The struggle to save Henry’s life both validates concerns that the national healthcare system cannot function and also illustrates how Sierra Leone has brought itself closer to the scenario of a superbug crisis. The superbug stands in contrast to the cure by being the product of a protracted process of development. Ironically, the superbug can only develop through decades of neglect. By failing to properly treat TB and prevent its spread, the superbug develops at minimal cost. This extends Green’s argument that cost-effectiveness is an instrument for control that heightens suffering while also maximizing the risk of emergencies like a pandemic occurring. This was the case with COVID-19, which Green invokes in the same chapter as a global priority only once it started to affect rich countries like the United States. In highlighting this disparity, Green exposes how proximity to power—not severity of illness—often determines the urgency of medical response.


As Green nears the conclusion of Henry’s story, he expands his framework beyond individual experiences to show how systems either reinforce harm or build toward healing. He frames these patterns as opposing cycles—vicious and virtuous—that determine whether a person’s illness is compounded by neglect or transformed through care. By choosing to pursue specialized treatment, Dr. Girum, Henry, and Isatu chose to contribute to the virtuous cycle. Green ensures that his narrative shows how each person contributed to the cycle in their own way. Dr. Girum reached out to his international partners to find the cure that Henry needed. Henry exercised his right as an adult to remain in treatment. Isatu placed her trust in Lakka to save her son. On the other hand, the earlier chapters show how Henry’s father contributed to the vicious cycle, surrendering to the hopelessness of Henry’s disease. While this might have brought Henry’s father some emotional relief, it also brought the superbug closer to development by allowing Henry’s illness to evolve into a more resilient strain. By embedding these choices in broader structures of inequity and legacy, Green reinforces that individual action alone is not enough, but it can catalyze much-needed systemic change.


Green is not content with letting Henry’s story speak as the sole example of the virtuous cycle. He shows how Partners in Health’s move to develop guidelines for multiple drug-resistant TB patients helped Phumeza, allowing her to work as an activist in India. These further examples show how virtuous cycles are interdependent on one another. Green stresses this idea by highlighting how they work in a functioning healthcare system like that of the United States. His ability to avail of convenient medication speaks to the decades of investment that have been devoted to building the systems that saved his life. This underscores The Cumulative Power of Virtuous Cycles as a theme. These interconnected cycles reveal a simple but radical truth: When people are treated as worthy of care, they are more likely to survive and to care for others in turn.


Henry’s recovery is narrated in a way that is meant to bring relief to the reader. Green never alludes to the recovery at any point earlier in the book. Henry is always referred to in the past tense, and it is only after his treatment works that Green starts to refer to Henry’s life after TB in the present tense. This is intended to keep the tension high on the reader’s end, especially given the many deaths that occur throughout the book. This also maximizes the emotional impact of Henry’s decision to contribute to the virtuous cycle in his life. The shift in tense is more than a narrative device—it is a declaration of life reclaimed, of presence restored, and of a future made possible by persistence, solidarity, and care.


The Postscript is meant to catch the reader up on recent developments in TB healthcare. This is intended to show the reader how they might be able to contribute to the virtuous cycle, which isn’t exclusive to the work of activists and healthcare professionals. The discussion of the TB Hunters app, for instance, shows how software engineering can be used to contribute to the virtuous cycle. Likewise, Henry’s work on social media drives awareness to the disease in the hope of erasing the stigma that emotionally affects the people who suffer from TB. Because of the system that saved his life, Henry has gotten the chance to pursue an advocacy that brings awareness to the disease. He saves lives by speaking his truth to power, driving The Need for Empathetic Thinking as a theme. In offering the reader tangible entry points—from app development to sharing a survivor’s story—Green reframes global health as a communal responsibility, not a specialized pursuit.


Taken together, Chapters 18 through the Postscript serve as the book’s final moral argument: that injustice, not biology, is the most persistent driver of disease. Green does not ask the reader to marvel at Henry’s survival but to see it as a blueprint. In calling TB a disease of imagination, Green points not just to how we imagine illness but to how we imagine responsibility, possibility, and care. If we have the collective power to create vicious cycles, we also have the power to end them. In this way, Everything Is Tuberculosis becomes not just a study of disease but a call to reimagine what it means to live in shared humanity.
