From Refusal to Recovery: What One Family Taught Us About Health Literacy in TB
Published in Biomedical Research, General & Internal Medicine, and Public Health
The idea for this study was not born in a planning meeting or from a statistical anomaly, it came from a conversation. One of those field moments that unsettles you long after the day’s work is over. We were collecting qualitative data for another TB-related study when we met an elderly man recently diagnosed with tuberculosis. He had started the standard treatment regimen, including rifampicin, a core anti-TB drug known for turning urine a bright orange-red. Health workers had thoroughly explained this to him at the time of diagnosis. The change in urine color was expected, they said. Nothing to worry about. A sign the medicine was doing its job.
But within a few days, he stopped his medication.
When the team visited to check in, he told them he was frightened, his urine had turned orange, and in his words, “I was fine before the medicine. Now I’m sick.” He was not being defiant. He was afraid. And no matter how carefully the health staff reiterated the message about rifampicin, about harmless side effects, he simply did not believe it. His wife, also undergoing TB treatment, had quietly stopped hers too. A physician visited. So did a TB program officer. Each tried to reassure him, to build trust. But the man remained unconvinced. He saw the medicine as the source of his illness, not the cure.
What shifted the story was unexpected. A seasoned frontline health worker, after repeated failed attempts, asked the couple’s daughter to speak with them. She sat beside her father, spoke gently, and told him that she wanted him to live. That he had to trust the medicine, for her. And somehow, through that familiar voice, the message landed. It wasn’t the information that changed it was the messenger, the relationship, the trust. The couple resumed treatment.
That moment stayed with us not just for its emotional impact, but because it exposed a gap we hadn’t fully grasped before. The health system had done what it was supposed to: deliver accurate information, early and clearly. But something still broke down. It wasn’t a failure of knowledge transmission, strictly speaking, it was a failure of comprehension, belief, and alignment. We began to think deeply about what had worked in that interaction. Why did the daughter succeed where trained professionals could not? What allowed her words to be heard and accepted? That’s when the concept of health literacy moved from theory to urgency for us.
Health literacy is often spoken about in broad terms recognized as important, yet seldom examined through the lived experiences of patients.. But in that moment, it was everything. Not just the patient’s own ability to understand the medicine, but the role of his daughter in translating information into meaning. The more we thought about it, the more we recognized that TB care often assumes a linear model: diagnosis, counselling, adherence. But real life is rarely linear. Beliefs, fears, side effects, and social dynamics all shape how treatment unfolds. That experience made us ask: How health literate are TB patients, really? Especially those with multiple conditions? And can we begin to measure this in a way that offers actionable insight?
Our study, recently published in Discover Public Health, set out to assess health literacy among individuals with tuberculosis in India, including those with TB multimorbidity. TB patients are not a monolith. Some are managing diabetes, others HIV or other chronic illnesses. These intersections complicate health information, introduce multiple care providers, and demand far greater agency from patients navigating the health system. We used a structured tool to assess both functional and critical health literacy. Not just whether people could read health materials, but whether they could apply what they learned, ask questions, and make decisions.
The results were sobering. A significant proportion of participants demonstrated low health literacy, and this was more pronounced among patients with TB multimorbidity. This raises uncomfortable but necessary questions for TB programs. Are we measuring the right things when we assess program success? Are we assuming comprehension when we see compliance? And most importantly, are we equipping patients not just with pills and appointments, but with the clarity and confidence to navigate their treatment?
The man who refused rifampicin wasn’t resistant, he was confused, frightened, and overwhelmed. The health system gave him a medicine. His daughter gave him understanding. While our study focuses on individual health literacy, our fieldwork constantly reminded us of the social dimension what some scholars call distributed health literacy. A patient’s ability to make informed choices is not just about their own capacity, but also the people they trust, the language they speak at home, the cultural frames they live within.
We don’t claim to have all the answers. But we believe health literacy must be treated as foundational to TB care, especially as India moves toward ambitious TB elimination goals. Our study is a first step a mapping of where patients stand. The next steps are equally urgent: tailoring communication strategies, supporting caregivers, equipping frontline workers not just to inform, but to ensure understanding. Because ultimately, TB elimination is not just a biomedical challenge, it’s a human one.

Antimicrobial Resistance: The New Challenge to Global Health in a Post-Pandemic World
Antimicrobial resistance (AMR) is a seriously ongoing threat to global health, occurring when bacteria, fungi, viruses, and parasites evolve to resist the drugs designed to kill or block them. The COVID-19 pandemic has both directly and indirectly exacerbated the problem of AMR, as the overuse of antibiotics has accelerated the development of resistance in many pathogens. COVID-19 may have subsided, but AMR continues to pose a significant risk to the effectiveness of global healthcare systems, threatening to reverse decades of progress in combating infectious diseases. The interplay between population health and AMR has become increasingly critical as healthcare practices have shifted in response to the pandemic. Understanding this relationship is essential for developing effective strategies to mitigate the impact of AMR on population health in a post-COVID context.
The motivation for launching this Collection arises from the urgent need to address the rising tide of AMR as healthcare systems grapple with the long-term effects of the pandemic. Increased antibiotic use during COVID-19 treatment, changes in healthcare access, and disruptions in public health interventions have all contributed to an environment where AMR can thrive. Moreover, the pandemic has highlighted the importance of a multidisciplinary approach to tackling AMR, involving epidemiology, policymaking, and community health initiatives. This Collection aims to provide a platform for researchers and practitioners to share insights and findings that can inform future strategies to combat AMR while considering the broader implications for population health.
This Collection aims to highlight the multifaceted nature of AMR in a post-pandemic environment. We solicit articles that investigate the particular issues provided by the pandemic in terms of AMR development and containment, examine the impact of AMR on many sectors of healthcare, and propose novel strategies to minimize resistance propagation. Submissions may include original research, policy assessments, program evaluations, and comments on the following major areas:
• Epidemiology and trends of AMR post-pandemic
• Impact of COVID-19 on antibiotic usage
• Surveillance strategies for AMR
• AMR and stewardship
• Prevention and control measures to limit AMR spread
• Policies and programs to promote antibiotic stewardship
• Economic and social implications of AMR
• Global collaboration and initiatives to tackle AMR
By addressing these critical issues, this Collection aims to provide a comprehensive understanding of the emerging challenges in antimicrobial resistance in a post-pandemic world and to promote effective strategies to preserve the power of our current antimicrobials.
