India's Allergy Renaissance: A Blueprint for Global Capacity Building

Allergic diseases represent a substantial public health concern worldwide, including in low- and middle-income countries (LMICs), where urbanisation, environmental change and evolving health-seeking behaviour influence patterns of healthcare utilisation [1-3]. India, home to nearly one-fifth of the world's population, carries a significant burden of allergic rhinitis, asthma, food allergy, atopic dermatitis and anaphylaxis [1, 4]. Alongside this established burden, increasing awareness, expanding allergy research and growing demand for structured allergy services have begun to reshape the clinical and academic landscape. Until recently, however, allergy as a structured subspecialty lacked formal training pathways, nationally contextualised standards and coordinated public health strategies [5]. The year 2025 represented a period of accelerated coordination in India's allergy landscape. A convergence of academic, clinical, policy and community initiatives contributed to a more system-level approach to allergy education and service development. This editorial outlines this evolving framework and explores its implications for global allergy practice. Key national initiatives across education, policy and public engagement are summarised in Table 1. pacesgrh.com cmch-vellore.edu daaicourse.org Historically, allergy care in India has been heterogeneous, characterised by variable diagnostic practices, limited structured training and inconsistent public awareness [6]. Recognising these gaps, the Indian Academy of Paediatrics (IAP) Allergy & Applied Immunology Chapter initiated a coordinated national strategy integrating education, clinical practice standards, public engagement and international collaboration [7]. The observance of 11th October as National Allergy Day by professional bodies has created a focal point for awareness and advocacy activities across schools, healthcare institutions and professional organisations. Although not yet formally designated by the Government of India, this initiative has helped catalyse coordinated public engagement and policy dialogue around allergic diseases. PedAllercon 2025, held in New Delhi, convened over 1000 delegates with participation from national and international faculty. Scientific sessions addressed precision medicine, component-resolved diagnostics, immunotherapy, biologics, aerobiology, chronic rhinosinusitis with nasal polyposis and food allergy. Academic platforms of this nature play an important role in LMICs, where multidisciplinary dialogue can reduce fragmentation and promote more consistent standards of care. A significant development has been the creation of nationally contextualised allergy practice parameters covering major allergic conditions [7]. These parameters adapt international evidence to local epidemiology, healthcare infrastructure and economic realities. In LMIC settings, contextualisation is critical to ensure that diagnostic strategies, immunotherapy protocols and advanced therapies are implemented judiciously and equitably. Such guidance may also reduce inappropriate testing and unnecessary escalation of care, an issue of growing relevance in many health systems [6]. A major constraint in allergy care globally is the limited number of formally trained specialists [5]. In India, most patients are initially evaluated by general paediatricians and other organ-based specialists. To address this, layered educational initiatives—including certificate and diploma programmes, modular scientific updates and cross-specialty collaborations—have aimed to strengthen foundational allergy competencies. The launch of ‘Allergy School’ represents a further step toward structured advanced training, signalling gradual movement toward more formalised academic pathways. Importantly, these initiatives are designed to promote rational, evidence-based care rather than expansion of unnecessary investigations or therapies. Public and school-based awareness programmes addressing food allergy, anaphylaxis, urticaria, eye allergy and asthma have complemented clinical initiatives. These programmes focus on early recognition, avoidance of misinformation and appropriate emergency preparedness. In many settings, delayed diagnosis and inconsistent management coexist with anxiety-driven over-treatment. Balanced public engagement is therefore essential to improve outcomes without contributing to unnecessary fear or medicalisation. Knowledge dissemination has occurred through national textbooks, practice manuals, structured educational bulletins and professional dialogues. These resources aim to standardise terminology, reduce practice variability and promote evidence-aligned approaches across diverse healthcare environments. In parallel, a growing body of basic, clinical and translational allergy research emerging from Indian centres is contributing to improved understanding of regional disease patterns, environmental determinants and therapeutic responses, further strengthening the scientific foundation of this evolving allergy ecosystem. Recognising the interconnected nature of allergy, asthma and sleep disorders, the ‘Initiative for Sleep, Asthma and Allergy Sciences (ISAAS)’ was launched as a multidisciplinary platform [8]. By fostering collaboration between allergists, pulmonologists, sleep specialists and paediatricians, such initiatives promote systems-based care models rather than organ-specific silos. International engagement has expanded through structured collaborations with global allergy societies. The EAACI–NAIS dual membership initiative, for example, facilitates academic exchange and access to educational resources. Regional outreach programmes within South Asia support knowledge sharing in contexts with similar environmental exposures and healthcare structures. Such bidirectional collaborations strengthen both local capacity and global understanding of allergy implementation challenges. These interacting components can be conceptualised as an integrated ecosystem model (Figure 1). As healthcare utilisation patterns and patient expectations evolve globally, health systems are experiencing increasing demand for structured, evidence-based allergy services. From an implementation science perspective, India's experience illustrates how coordinated professional leadership, contextualised guidelines and task-sharing educational models can accelerate the translation of allergy knowledge into scalable health system practice. Challenges remain. Formal recognition of allergy as a subspecialty, structured national training pathways, reimbursement frameworks for advanced diagnostics and biologics and the development of national registries are important next steps. Equally critical is the evaluation of measurable outcomes—such as diagnostic appropriateness, rational biologic use and patient-reported outcomes—to ensure that expansion of services translates into improved value-based care. India is undergoing a coordinated evolution in allergy education, guideline development, public engagement and international collaboration. Rather than reflecting an epidemiological surge, this transformation represents a health system response to increasing awareness and service demand within an established disease burden. For other low- and middle-income countries, this integrated allergy ecosystem model may provide a pragmatic framework for strengthening workforce capacity, standardising care pathways and translating emerging allergy science into scalable health system practice.
