1. Framing the need for a "just transition" for drug-resistant tuberculosis
Tuberculosis (TB) remains a serious global health threat, and strains resistant to first-line therapies account for an important share of TB-related illness and death.Footnote 1 Already known as a disease of poverty concentrated in low- and middle-income countries (LMICs), drug-resistant tuberculosis (DR-TB) highlights not only deep-seated deprivation but also the shortcomings of under-resourced health systems.Footnote 2
Traditionally, the response to TB, and particularly DR-TB, has been focused on dealing with the infection and preventing onward transmission, for example, through isolating people with TB in sanatoria or specialized hospital wards. The needs (and preferences) of people with TB disease were hence considered subordinate to the public health imperative of preventing onward transmission.Footnote 3 Recently, activists and policy makers have recognized the need to put people at the center of the approach to TB, but this is just the beginning of the necessary “just” transition from inequitable and unsustainable approaches to addressing TB towards ones that are inclusive, community-centered, and resilient.Footnote 4
In this article, we examine antimicrobial resistance (AMR) in TB. We focus on DR-TB because of the particular need for a multisectoral, justice-oriented approach that goes beyond biomedical paradigms—we propose this as a “just” transition that addresses the unequal burden of human suffering in its fullness and seeks to address injustices that have become systemic in TB programs.Footnote 5 The injustices include the uneven distribution of diagnostic capacity, the lack of investment in and availability of effective and tolerable treatment, and the exclusion of people affected by TB from shaping program priorities.Footnote 6 These programmatic inequities lead to delayed treatment initiation, particularly in rural areas, worse treatment outcomes, and deepened marginalization among already vulnerable populations. In discussing this transition, we draw from scholarship around equity considerations in response to the climate crisis and see a “just transition” as involving long-term structural changes to technologies, policy, infrastructure, scientific knowledge, and practice.Footnote 7
2. Poverty and drug-resistant TB
Globally, the burden of TB is concentrated in LMICs.Footnote 8 Furthermore, the poorest in societies are also at greatest risk of developing the disease.Footnote 9 Overcrowded housing and malnutrition are key drivers of TB, its transmission and the development of active disease.Footnote 10 The risk of TB is also particularly high among people living with HIV, another infection that is entwined with global and local inequities.Footnote 11 And with multiple episodes of TB, the risk of DR-TB increases.Footnote 12
Poverty compounds the impacts of an episode of TB, whilst TB also has economic impacts for individuals and families. The poorest in society often struggle to deal with the economic burden of accessing TB care and following the treatment regimens, which—because of direct travel and treatment costs as well as indirect opportunity costs—can exceed 50% of annual household income.Footnote 13 Moreover, an episode of TB often leaves long-term sequelae, which are poorly understood and can be life-limiting.Footnote 14 Moreover, long-term sequelae of TB often require extended rehabilitation, which entails long-term healthcare expenditures and compounds financial hardship.Footnote 15
These impacts are particularly pronounced in the case of DR-TB.Footnote 16 The treatment regimens are longer (lasting from 6 to 20 months) and their toxicity profiles—although much improved over recent years—can have long-term health impacts.Footnote 17 Treatment regimens for DR-TB vary according to the specific resistance profiles (and sometimes limited drug susceptibility testing), but they are often less tolerable and more complex than those for drug-susceptible TB. Treatment can also involve switching between regimens, which prolongs the course. With the higher drug toxicity and increased pill burden, people with DR-TB often face adherence challenges and treatment success rates remain lower than for drug-susceptible TB, often below 60% in high-burden settings.Footnote 18 Treatment regimens for DR-TB carry substantial risks of adverse effects, including peripheral neuropathy from linezolid and hepatotoxicity from other agents, further complicating adherence.Footnote 19
For those affected by TB, the consequences are not only health-related; rather they often also face catastrophic health expenditures and loss of livelihood. For example, in Zimbabwe, DR-TB–affected households experienced a median loss of 67% of annual income due to treatment costs, travel expenses, and lost wages.Footnote 20 These long-term livelihood impacts can drag families into a spiral of poverty and food insecurity that further increases their risk of TB.Footnote 21 There are psycho-social consequences, with people affected by TB unable to fulfill their social (or economic) roles and experiencing social isolation and othering because of TB-related stigma.Footnote 22
3. Inequities in approaches to addressing TB
The challenges of addressing DR-TB mirror those of AMR more broadly. Key issues across LMICs include insufficient laboratory capacity, inadequate drug development supply chains, and under-resourced primary health facilities.Footnote 23 These problems contribute to delayed diagnoses, suboptimal treatment, and persistent transmission, which promote the emergence and spread of resistance traits.Footnote 24 In DR-TB, this is particularly pronounced because of the difficulties of identifying resistance, the complex treatment regimens, and the interactions with HIV infection.Footnote 25
In LMICs, diagnostic and laboratory infrastructure for DR-TB is often inadequate, particularly in primary care facilities and communities.Footnote 26 Identifying resistance in TB still often relies on culture-based laboratory processes, which take weeks. Even though more rapid molecular sequencing approaches have been developed, the lack of resources and infrastructure prevents their implementation in many LMICs.Footnote 27 Hence, receiving a diagnosis can involve repeated long-distance travel to reach diagnostic centers and multiple provider consultations. This means prolonged work absenteeism, income loss, direct expenses for tests not covered by public health programs, and social stigma that exacerbates emotional distress.Footnote 28
The challenges of treating DR-TB are particularly pronounced because—in spite of recent improvements—regimens are often long, toxic, and difficult to access. Positive developments include the recently recommended all-oral regimens that contain bedaquiline, pretomanid, and linezolid (BPaL), although they still require at least 6 months of treatment.Footnote 29 However, bedaquiline was the first new drug specifically developed for TB in more than 40 years, and although it represents a major therapeutic advance, it is the result of an antibiotic pipeline with few future candidate compounds.
Global access to bedaquiline also remains uneven—regulatory approval is incomplete in several high-burden countries, and treatment costs can be prohibitive for uninsured patients.Footnote 30 Donation programs, such as the Janssen bedaquiline initiative, have provided some relief but have been insufficient to meet demand sustainably.Footnote 31 Hence, inadequate health systems mean that even when effective tools exist, they do not reliably reach those who need them most. The poorest often face the double burden of failing health systems and burdensome treatment regimens. Highlighting the moral imperative to accelerate research and delivery of shorter and more tolerable (DR-)TB regimens.Footnote 32
4. A necessary “just transition”
Addressing DR-TB as part of broader AMR stewardship requires transformation along the care trajectory, from screening and diagnosis to treatment. Equitable access to rapid, reliable diagnostics and strengthening laboratory systems for early detection and tailored treatment is essential. Integrating AMR management into TB diagnostic platforms, especially at peripheral health facilities, can enhance efficiency and improve patient outcomes.Footnote 33 Investment in new treatments is also essential to identify less toxic and shorter regimens for DR-TB. These are approaches that reflect interventions deeply rooted in biomedical models that prioritize pathogen-specific interventions, drug development, and clinical protocols. Although indispensable, they are insufficient when decoupled from broader health system strengthening.Footnote 34 Alone, they also neglect the recent shift in TB programming and care toward a more person-centered approach.Footnote 35
Person-centered care is characterized as holistic, individualized, respectful, and empowering, with the person (with TB) central to the process of care through informed, shared decision-making and self-determination.Footnote 36 In person-centered care, the person affected by TB and healthcare providers engage in collaborative decision-making, discussing options, treatment risks, and benefits.Footnote 37 In this approach, the person affected by TB is an active participant, rather than a passive recipient of care.Footnote 38
Although the shift to person-centered care is essential, it is only the start of a transition needed to address DR-TB in an effective and fair manner. In considering what is needed, we draw from the concept of a just transition—a socio-technical transition, which involves deep structural changes in systems, and entails long-term and complex changes to technologies, policies, infrastructure, scientific knowledge, and social and cultural practices.Footnote 39 This “just” transition requires moving beyond a narrow biomedical approach to one that integrates social, economic, and systemic determinants of health.Footnote 40 These investments must be planned and financed as part of broader health system reforms, ensuring they serve multiple health needs.
A “just transition” for TB means confronting the structural forces that seed vulnerability in the first place. Although new drugs, diagnostics, and vaccines are essential, their impact will be compromised unless they are paired with policies that address crowded housing, insecure work, malnutrition, weak labor protections, and the marginalization of affected communities. A truly just transition therefore reframes TB control as a question of distributive justice and democratic accountability: reallocating resources toward social protection schemes, strengthening primary health services, guaranteeing living wages, and empowering communities to shape research priorities and service delivery.Footnote 41 In other words, it shifts the center of gravity from laboratories and hospitals to the everyday environments where risk is produced—and where equitable social and economic reforms can dismantle the very conditions that allow drug-resistant strains to flourish.
Reframing the approach to DR-TB through the lens of “just transitions” invites us to imagine a different future: one in which science and solidarity go hand in hand; in which innovation is directed by the concept of health equity; in which communities are empowered and viewed as equal partners, not passive recipients and in which the right to health is realized universally.
5. Engendering the transition
This future will not emerge spontaneously; it requires deliberate choices, courageous leadership, and sustained advocacy. By embracing the principles of justice, inclusivity, and systemic transformation, we can build a shared future that is not only more resistant to the threats of TB and AMR but also more aligned with the values of human dignity and collective well-being. Declarations from recent high-level United Nations meetings on TB have incorporated human rights commitments, including the right to health, to ending stigma and discrimination against people affected by TB, and promoting access to affordable treatments.Footnote 42 Countries have, however, often not met these commitments.Footnote 43 Furthermore, although the WHO’s End TB Strategy and most national AMR action plans recognize equity in principle, they rarely embed enforceable measures that channel resources to the communities carrying the heaviest burden of resistance.
Individuals living in vulnerable situations often lack the opportunity and agency to voice their needs and ideas. Effective TB responses must be grounded in the realities of affected communities.Footnote 44 Communities can be key agents in TB elimination when appropriately supported, for example, India’s TB Mukt Panchayat initiative and community health worker programs in South Africa, which improved case detection and treatment adherence.Footnote 45 Community engagement is not an optional add-on but a foundational element of a just transition.Footnote 46 People-centered approaches, including the involvement of TB survivors, grassroots health workers, and civil society organizations, have demonstrated impact in improving case detection, reducing stigma, and supporting treatment adherence.Footnote 47 However, in many settings, community-based responses are underfunded, under-researched, and inadequately integrated into national health strategies. A just transition means rebalancing these inequities and investing in the leadership, capacities, and innovations of communities themselves. Communities are key agents in TB elimination efforts, offering culturally grounded, trusted interventions that complement formal health systems.Footnote 48
Research agendas must also reflect the lived realities of patients and the systemic barriers they face. Innovation must not only produce new tools but also address affordability, accessibility, and usability in real-world settings.Footnote 49 A just transition envisions research driven by public health needs rather than commercial priorities, supported by financing mechanisms that prioritize equitable access. At the same time, the ethics of innovation must be scrutinized.Footnote 50 Who sets the agenda? Who benefits? Who is left behind? These questions are particularly relevant in the context of TB, for which global North–South power imbalances continue to influence funding, policy, and access to tools.
