India’s rural, tribal, and migrant communities continue to struggle significantly against tuberculosis (TB), a recent report highlights. These vulnerable populations face deep-rooted challenges, including widespread poverty, social stigma, and limited access to healthcare, which hinder national efforts to eliminate the disease. India carries the world's highest TB burden, accounting for 26% of all global cases and deaths in 2023. T^[1][2]his persistent crisis underscores the urgent need for targeted interventions and stronger health infrastructure in these underserved regions. ### Tribal Communities Face Disproportionate TB Burden Tribal communities in India experience a particularly high burden of tuberculosis, with a prevalence of 703 cases per 100,000 people. This is significantly higher than the national average of 316 per 100,000 population, according to National Family Health Survey (NFHS-5) data from 2019-2021. G^[3][4]eographical isolation, poor healthcare facilities, and limited access to care contribute to this disparity. Many tribal areas lack adequate health infrastructure and trained personnel, making timely diagnosis and treatment difficult. ^[5][6][7][4]Malnutrition is a critical factor exacerbating TB in these groups. Over 50% of TB patients in India suffer from undernutrition, a rate that climbs to 51.4% among tribal populations. S^[8][9]tudies show undernourished individuals are more susceptible to active TB, and the disease further worsens their nutritional status. C^[8][10]ultural barriers also play a role, with many tribal communities relying on traditional healers, which can delay access to modern medical care. A^[11][4] report from the Indian Council of Medical Research (ICMR) and the National Institute for Research in Tuberculosis (NIRT) noted that nearly 75% of tribal individuals with TB-like symptoms do not seek prompt medical care. ^[11]Stigma surrounding TB is often more severe in tribal and rural communities than for HIV, leading many to delay seeking treatment. M^[12][11]isconceptions about TB being incurable remain widespread. F^[11]or instance, residents in underdeveloped tribal areas like Chhattisgarh face hardships such as transportation shortages, irregular drug supplies, and economic insecurity, further complicating their fight against the disease. ^[11]### Migrant Workers Battle Unique Obstacles India's vast internal migrant population, estimated to exceed 100 million, also faces unique and severe challenges in accessing TB care. T^[5]heir transient lifestyles often interrupt treatment continuity and adherence. M^[5]igrant laborers, especially in sectors like construction and brick kilns, frequently live in overcrowded, unsanitary conditions with poor ventilation, which fosters the spread of airborne diseases like TB. ^[5][13]Many migrant workers hold informal employment without health benefits, making them hesitant to take time off work for medical help. T^[5]hey often lack government-issued identity cards, further blocking access to public healthcare services. S^[5]tigma is another significant barrier, deterring individuals from seeking help due to fear of ostracization from employers and co-workers. L^[5][14]imited access to healthcare, cultural and linguistic differences, and general social and economic challenges like poverty and unemployment contribute to delayed diagnosis and the potential spread of multidrug-resistant TB (MDR-TB). L^[14]osing daily wages is a major deterrent for migrant workers seeking care. ^[15]### Stigma and Treatment Adherence Remain Key Hurdles Across all these vulnerable groups, stigma associated with tuberculosis profoundly impacts care-seeking behavior and treatment adherence. A community-based survey in 30 Indian districts found that 73% of people held stigmatizing attitudes towards TB patients. T^[16]his stigma causes individuals to delay seeking diagnosis and often leads to poor adherence to their treatment regimens. ^[16][7][17]Treatment non-adherence is a significant issue. Studies indicate that 11.8% of patients are non-adherent, and 17.8% show suboptimal adherence to TB medications. F^[18][19]actors contributing to poor adherence include the loss of daily wages, travel costs to treatment centers, and the side effects of anti-TB drugs. T^[20][18][21]he economic burden on patients is substantial; 56% to 61% of TB patients face "catastrophic costs," defined as total treatment costs exceeding 20% of their annual household income. H^[22]alf of these costs often occur during the average nine-week delay from symptom onset to diagnosis, as patients make multiple visits to various healthcare providers. ^[22]The COVID-19 pandemic further disrupted TB services across the country, leading to a backlog of undiagnosed cases and impacting ongoing treatment programs. T^[23][1][7]he persistent threat of drug-resistant TB, which requires longer and more expensive treatment regimens, also poses a formidable challenge. ^[24][7]### India's Efforts to Combat TB The Indian government's National Tuberculosis Elimination Programme (NTEP) aims to eliminate TB by 2025, five years ahead of the global target. T^{[6][24][1][25]}he NTEP has re-strategized its interventions to specifically focus on vulnerable populations to reduce TB incidence and mortality. T^[2]hese measures include providing free drugs and diagnostics, conducting active TB case-finding campaigns in high-burden areas, and integrating TB screening and treatment services with Ayushman Arogya Mandir health centers. ^[2][26]The program also emphasizes private sector engagement and has scaled up molecular diagnostic laboratories to sub-district levels. N^[2]utritional support is crucial, with initiatives like the Nikshay Poshan Yojana and Nikshya Mitra providing financial and nutritional aid to TB patients. F^[24][2]or tribal, hilly, and difficult areas, NTEP has implemented additional provisions such as establishing more TB program management units and microscopy centers, and offering a one-time incentive of Rs 750 to cover patient travel costs. D^[26]espite these efforts, India still faces a long road to achieve its ambitious TB elimination goal.
