Outdated TB Approaches Persist as India Fights Global Epidemic

As World Tuberculosis Day approaches on March 24, 2026, experts are underscoring the critical need to overhaul the global approach to tuberculosis (TB) control, arguing that current strategies are largely outdated and inefficient. The theme for World TB Day 2026, 'Yes! We can end TB!', with an emphasis on being 'Led by countries, powered by people', highlights the collective ambition, yet also the persistent obstacles in achieving TB elimination. The existing framework is criticized for its 'silo system' and for treating TB in isolation, rather than as a multifaceted disease intertwined with broader health and socioeconomic factors. One major claim from the article is that viewing TB through a narrow clinical lens is insufficient. It advocates for addressing systemic inefficiencies and looking at the lives of those affected, beyond just their lungs. This aligns with the World Health Organization's (WHO) 'End TB Strategy,' adopted in 2014, which calls for integrated, patient-centred care, bold policies, and supportive systems involving governments, communities, and private stakeholders, alongside research and innovation. The article highlights that TB is frequently accompanied by comorbidities such as diabetes, malnutrition, and HIV. People living with HIV are significantly more susceptible to TB, being 16 times more likely to fall ill with the disease. Similarly, diabetes can increase the risk of TB by two to three times. Malnutrition is also a well-established strong risk factor for latent TB infection and is particularly prevalent in high-burden countries like India. Addressing these co-existing conditions is vital for effective TB control. A significant barrier identified is the 'gender gap' in TB care. Statistically, men globally bear a higher burden of TB, accounting for approximately 55% of all cases, compared to 33% for women and 12% for children, according to the WHO. Despite this, men are often the hardest to engage in the care system. This disparity is attributed not to biological reasons, but to 'structural failure' rooted in gendered social norms. As primary earners, the fear of lost wages combined with the social stigma associated with a TB diagnosis creates a powerful disincentive for men to seek timely medical care. For an audience in India, the challenges presented by TB are particularly acute. India continues to grapple with the world's largest TB epidemic, accounting for an estimated 25% to 28% of all new TB cases globally. In 2024, the country reported the highest number of TB cases worldwide. The problem is further compounded by a substantial burden of drug-resistant TB (DR-TB), with India contributing around one-third or 27-32% of global multidrug-resistant (MDR-TB) and rifampicin-resistant (RR-TB) cases. Despite ambitious targets set by the Indian government to eliminate TB by 2025, the incidence rate in 2024 (187 cases per lakh population) remains considerably higher than the 77 cases per 100,000 target. While India has made progress, achieving a 21% reduction in TB incidence between 2015 and 2024 (nearly double the global rate of decline), significant hurdles remain. These include inadequate primary healthcare infrastructure in rural areas, an unregulated private healthcare sector that often provides suboptimal care and leads to high dropout rates, lack of public awareness, poor notification of cases, and the persistent stigma surrounding the disease. Suboptimal quality of care in the private sector can lead to delayed diagnoses, incorrect treatment protocols, and higher risks of drug resistance. The treatment success rate for MDR-/RR-TB in India varies, with some reports showing it around 48% compared to a global average of 56%, while other more recent reports indicate improvements to 77% or even 90% for new cases under specific initiatives. The way forward, as proposed by the article and corroborated by global health bodies, involves embracing new tools and strategies. This includes the rapid adoption of innovative technologies like AI-powered handheld X-ray devices for high-volume screening, which are already being utilized in over 22 countries. Advances in molecular diagnostics are improving the speed and accuracy of TB diagnosis, and new, shorter treatment regimens are becoming available for both drug-sensitive and drug-resistant TB. India's National TB Elimination Programme (NTEP) and the National Action Plan on Antimicrobial Resistance are working towards expanding surveillance, improving diagnostics, and promoting responsible antibiotic use. The renewed focus must be on integrated, patient-centred care that tackles the complex interplay of medical, social, and economic factors that perpetuate the TB epidemic, demonstrating leadership and courage to fix systemic issues. World Tuberculosis Day on March 24th commemorates Robert Koch's discovery of the TB bacillus in 1882, a breakthrough that paved the way for diagnosis and treatment. However, over a century later, the fight against TB demands a truly modern and holistic approach to fulfill the promise of a TB-free future.
