Epidemiologic patterns strongly suggest that the decrease in cases resulted from an interruption in the ongoing spread of M. tuberculosis infection, primarily because of better rates of completion of treatment and expanded use of directly observed therapy. Another contributing factor may have been efforts to reduce the spread of tuberculosis in institutional settings, such as hospitals, shelters, and jails. Expansion of measures to prevent and control tuberculosis and support of international control efforts are needed to ensure continued progress.

growing political momentum to definitively address tuberculosis, could all make ending the pandemic within a generation more feasible than ever before. Moving forward with bold, comprehensive strategies Globally, the priority must be to deliver person-centred and family-centred services to all individuals with tuberculosis who present to care. This approach means ensuring that high-quality diagnostics, treatment, and prevention modalities are available to all, wherever they seek care. Improving quality of tuberculosis care in the private sector is crucial to end tuberculosis in high incidence countries such as India, the country with the highest tuberculosis burden. Modelling shows that optimising private sector engagement in India could avert 8 million deaths from tuberculosis between 2019 and 2045 (appendix p 3). In high drug-resistant tuberculosis burden countries, access to rapid drug susceptibility testing (DST) and second-line drugs is essential to success. In Moldova, where more than 25% of all tuberculosis cases are drug-resistant, improving access to DST and second-line drugs would reduce mortality from drug-resistant tuberculosis by 44% in the coming generation (appendix p 3). Secondly, tuberculosis programme budgets must increase to enable reaching these people and populations at high risk of tuberculosis. In Kenya, for example, where the proportions of HIV and tuberculosis coinfection are high, scaling up access to both antiretroviral therapy and tuberculosis preventive therapy can help save an additional 3 million lives over the next generation (appendix p 3). However, ultimately, the fight against tuberculosis will not be won unless countries also ensure that everyone, not just high-risk groups, can access essential health Key messages The Commission recommends five priority investments to achieve a tuberculosis-free world within a generation. These investments are designed to fulfil the mandate of the UN High Level Meeting on tuberculosis. In addition, they answer the question of how countries with high-burden tuberculosis and their development partners should target their future investments to ensure that ending tuberculosis is achievable. Invest first to ensure that high quality rapid diagnostics and treatment are provided to all individuals receiving care for tuberculosis, wherever they seek care This priority includes rapid drug susceptibility testing and second-line treatment for resistant forms of tuberculosis. Achieving universal, high-quality person-centred and family-centred care-including sustained improvement in the performance of private sector providers-usually should be the top policy and budget priority. Reach people and populations at high risk for tuberculosis (such as household and other close contacts of people with tuberculosis, and people with HIV) and bring them into care Active case-finding and treatment in high-risk populations demands adequate resources to reach and care for these populations. At the same time, reaching certain high-risk populations, such as people co-infec...

Mycobacterium tuberculosis is recognised as the primary cause of human tuberculosis worldwide. However, substantial evidence suggests that the burden of Mycobacterium bovis, the cause of bovine tuberculosis, might be underestimated in human beings as the cause of zoonotic tuberculosis. In 2013, results from a systematic review and meta-analysis of global zoonotic tuberculosis showed that the same challenges and concerns expressed 15 years ago remain valid. These challenges faced by people with zoonotic tuberculosis might not be proportional to the scientific attention and resources allocated in recent years to other diseases. The burden of zoonotic tuberculosis in people needs important reassessment, especially in areas where bovine tuberculosis is endemic and where people live in conditions that favour direct contact with infected animals or animal products. As countries move towards detecting the 3 million tuberculosis cases estimated to be missed annually, and in view of WHO's end TB strategy endorsed by the health authorities of WHO Member States in 2014 to achieve a world free of tuberculosis by 2035, we call on all tuberculosis stakeholders to act to accurately diagnose and treat tuberculosis caused by M bovis in human beings.

Low-and middle-income countries (LMICs) bear a disproportionately high burden of the global morbidity and mortality caused by chronic respiratory diseases (CRDs) including asthma, chronic obstructive pulmonary disease, bronchiectasis and post-tuberculous lung disease. CRDs are strongly associated with poverty, infectious diseases, and other non-communicable diseases, and contribute to complex multi-morbidity, with significant consequences for the lives and livelihoods of those affected.The relevance of CRDs to health and socioeconomic wellbeing is expected to increase over time, as life expectancies rise and the competing risks of early childhood mortality and infectious diseases plateau. As such, the World Health Organization has identified the prevention and control of CRDs as an urgent development issue and essential to the achievement of the Sustainable Development Goals.In this review we focus on CRDs in low-and middle-income settings (LMICs). We discuss the early life origins of CRDs, challenges in prevention, diagnosis and management in LMICs, and pathways to solutions to achieve true Universal Health Coverage.
