Health Technology: Ayushman Bharat Digital Mission, Tele-MANAS & Medical AI

1. AYUSHMAN BHARAT DIGITAL MISSION (ABDM)

Cue Words	Notes
ABDM Architecture: The Three Registries	**ABHA ID**: A 14-digit unique health identifier centralising a citizen's electronic health records (EHR) across clinics, laboratories, and insurers. **Healthcare Professionals Registry (HPR)**: Verified national database of all registered doctors, nurses, and paramedical practitioners. **Health Facility Registry (HFR)**: Maps all public and private medical facilities — hospitals, clinics, diagnostic centres — nationwide. **Interoperability Standards**: Standardise health-data exchange so digital transfers replace physical patient files, cutting diagnosis time.
Scale & 2026 Trajectory	**ABHA Scale**: Crossed **90+ Crore ABHA accounts** with over **100 Crore health records** digitally linked by the National Health Authority (NHA) — up sharply from the ~86 Crore/38 Crore mark of the prior cycle. **Revamped ABHA App**: NHA's redesigned app introduces a memorable ABHA Address (username@abdm) alongside the 14-digit ID, plus OCR-backed "Smart Reports" and a "Scan & Register" flow for faster onboarding. **National Health Claims Exchange (NHCX)** and **Unified Health Interface (UHI)**: Extend the ABDM stack into insurance-claims processing and appointment/service discovery respectively.

> **Summary**: ABDM has crossed the 90-Crore ABHA milestone and is now layering claims exchange (NHCX) and service discovery (UHI) atop its core registries — moving from identity infrastructure toward a full digital health transaction layer.

2. TELEMEDICINE, TELE-MANAS & TB ELIMINATION

Cue Words	Notes
eSanjeevani: World's Largest Government Telemedicine Network	**eSanjeevaniAB-HWC**: Provider-to-provider hub-and-spoke model, linking rural Sub-Centres/Health & Wellness Centres with specialist doctors at tertiary hospitals. **eSanjeevaniOPD**: Direct patient-to-doctor teleconsultation. **Reach**: Surpassed **46 Crore consultations** (~60% rural women), saving patients an estimated ₹2,000+ per visit in travel and lost wages.
Tele-MANAS & Ni-kshay	**Tele-MANAS**: Toll-free 24/7 mental-health counselling helpline operating **51 active cells across 36 states**, handling **32 Lakh+ cumulative calls** in 20 regional languages — destigmatising psychiatric care in rural tracts. **Ni-kshay Ecosystem**: AI-powered TB patient-tracking database; India bears **27% of the global TB caseload**. Tracks ~25 Lakh patients annually and channels ₹2,500 Crore in Direct Benefit Transfers via Ni-kshay Poshan Yojana for nutritional support.

> **Summary**: eSanjeevani and Tele-MANAS have institutionalised remote specialist access at population scale, while Ni-kshay's AI-driven tracking anchors India's TB-elimination push against its disproportionate 27% share of the global burden.

3. EMERGING MEDICAL AI, POINT-OF-CARE TECH & DATA PRIVACY

Cue Words	Notes
AI Diagnostics & Point-of-Care Testing	**AI Diagnostics & Radiomics**: Machine learning detects scan patterns (X-ray, CT, MRI) invisible to the naked eye — aiding early cancer screening and fetal-anomaly prediction. **Point-of-Care Testing (POCT)**: Portable, low-cost molecular diagnostic kits (e.g., paper-based microfluidic chips) bring infectious-disease detection down to the Primary Health Centre level.
Health Infrastructure Gaps & DPDP Compliance	**Spending Shortfall**: National Health Policy 2017 targets public health spending at **2.5% of GDP**; actual spend remains around ~1.3-1.4%. **Human Resource Gap**: India has **0.9 doctors and 1.7 nurses per 1,000 people**, below WHO norms (1 doctor, 3 nurses) — a constraint that AI-diagnostics and telemedicine partially offset but cannot substitute for. **DPDP Act 2023**: EHR data is classified as sensitive personal data; hospitals and health-data fiduciaries must maintain secure encryption and verified consent, facing heavy penalties for breaches.

> **Summary**: AI diagnostics and point-of-care tools are being deployed precisely to compensate for India's doctor-density shortfall, but this data-intensive expansion now runs squarely into DPDP Act 2023 compliance obligations for sensitive health data.

4. FRONTIER BIOMEDICAL TECHNOLOGIES: PRECISION THERAPY & DIAGNOSTICS

Cue Words	Notes
Cell & Gene-Delivery Therapies: From Lab-Built to In-Body CAR-T	**Conventional CAR-T**: Lab-modified patient T-cells (viral vectors, chemotherapy lymphodepletion) cost ₹60–70 Lakh/patient in India — a major access barrier despite indigenous options like NexCAR19. **In-body reprogramming**: mRNA delivered via CD8-targeted lipid nanoparticles engineers CAR T-cells directly inside the patient, skipping lab processing/viral vectors — a scalable, lower-cost precision-medicine trajectory. **Nanozymes & SPArc**: Antioxidant-mimicking nanoparticles (V₂O₅) target abnormal blood clotting; proton arc radiotherapy (SPArc) spares healthy tissue during tumour treatment — both illustrate a shift toward precision-targeted, lower-collateral-damage therapeutics.
Forensic Genomics & Imaging Breakthroughs	**Mass-casualty DNA identification** (e.g., Air India AI171): STR analysis for intact nuclear DNA, mtDNA for degraded/burnt remains, SNP analysis for the most degraded samples — a tiered forensic-genomics toolkit with disaster-management relevance. **LICONN & MagIC**: Tissue-expansion light microscopy (LICONN) and magnetic-isolation cryo-EM (MagIC) push structural/connectomic biology imaging resolution far beyond conventional limits, accelerating neuroscience and drug-target discovery. **Infrared-sensing hydrogel lenses**: Biocompatible upconversion nanoparticles extend human vision into near-infrared — dual-use potential in emergency/disaster response and clinical non-invasive diagnostics.

> **Summary**: India's biomedical-technology frontier is shifting from costly lab-built cell therapies toward cheaper in-body/nanoparticle-delivered precision treatments, while parallel advances in forensic genomics and super-resolution imaging expand both disaster-response and drug-discovery capability.

UPSC Mains PYQs

• Digital Health Missions: Evaluate the progress and structural challenges of the Ayushman Bharat Digital Mission (ABDM) in creating a seamless digital health ecosystem in India. Discuss how telemedicine platforms like eSanjeevani address the rural-urban healthcare divide. (15 Marks, 250 Words)
• AI in Healthcare & Data Privacy: Discuss the potential of AI-based diagnostics and point-of-care testing in bridging India's human-resource gap in healthcare. Examine the adequacy of the DPDP Act, 2023 in safeguarding sensitive digital health data. (10 Marks, 150 Words)

• Gene therapy is a collection of methods that corrects a genetic defect by delivering new genetic material into a patient's cells to replace, repair, or silence a faulty gene, restoring correct protein production; it is classified as somatic cell gene therapy (non-heritable, e.g., for haemophilia and sickle cell anemia) or germ cell gene therapy (heritable, preventing the defect in offspring), and delivered either in vivo (inside the body) or ex vivo (patient cells removed, modified in a lab, and returned).
• ADA-SCID (Adenosine Deaminase Severe Combined Immunodeficiency) is a genetic immune disorder that has been successfully treated using gene therapy, serving as a landmark case study in the field.
• Key limitations of gene therapy include its short-lived effect (often requiring repeated doses), its inability to correct chromosomal disorders, and the risk of triggering immune responses/side effects; in India, National Guidelines for Gene Therapy Product (GTP) Development and Clinical Trials are jointly issued by the Department of Biotechnology and the ICMR, specifying clinical, scientific, and regulatory procedures.
• CAR-T (Chimeric Antigen Receptor T-cell) therapy is a personalised immunotherapy that genetically engineers a patient's own T-cells to recognise and kill cancer cells; benefits include effectiveness against certain cancers, a single-dose treatment (unlike repeated chemotherapy cycles), shorter treatment duration, and faster recovery, while challenges include triggering severe immune reactions (cytokine release syndrome) and difficulty in selecting the right target antigen.
• NexCAR19 (actalycabtagene autoleucel) is designed to target cancer cells carrying the CD19 protein, a biomarker for B-lymphocytes (B-cells); it targets leukaemia and B-cell lymphomas (blood cancers) by using the patient's own genetically modified T-cells, in contrast to chemotherapy, which uses cytotoxic drugs.
• Qartemi is India's first globally benchmarked CAR T-cell treatment, specifically designed for adult B-cell non-Hodgkin lymphoma; seen as a significant step towards a cure for blood cancer, it works by genetically modifying the patient's own T-cells to recognise and attack cancer cells.
• Stanford University scientists have developed a privacy-focused Brain-Computer Interface (BCI) that requires a 'mental password' before neural signals can be decoded into text or speech, addressing rising concerns over mental privacy and misuse of neural data as BCI adoption grows.
• Key BCI applications include restoring speech and movement in patients with paralysis, spinal cord injury, or stroke, and monitoring brain activity to manage stress, depression, and neurological disorders; Blindsight extends this to vision restoration by directly stimulating the visual cortex via an implanted microelectrode array, enabling perception of visual patterns even without functional eyes or optic nerves.
• Kwashiorkor (protein-deficiency malnutrition in children aged 6 months-3 years, marked by oedema, enlarged fatty liver, and preserved subcutaneous fat) is distinguished from Marasmus (protein-and-calorie deficiency common in infants under 1 year, marked by absent oedema, no fatty liver, prominent ribs, and severe muscle wasting) — a classic differentiation for malnutrition-policy questions.
• India's rice fortification programme adds iron, folic acid and Vitamin B12 to rice at a 1:100 ratio via coating, extrusion and dusting, under initiatives like Saksham Anganwadi and Poshan 2.0; thalassemia and sickle cell anaemia patients are advised to avoid it due to iron-overload risk.
• Monkeypox (mpox), caused by an Orthopoxvirus, is a zoonotic disease endemic to Central and Western Africa; WHO declared it a public health emergency amid concerns the virus is evolving via genomic recombination to better infect humans, and the WHO-prequalified smallpox vaccine MVA-BN is used for protection.
• Wolbachia bacteria (naturally present in nematodes and arthropods, in eggs but not sperm) are being used as a vector-control tool — Wolbachia-infected mosquitoes are released to suppress populations of disease-transmitting mosquito species.
• India's TB elimination strategy spans the National Tuberculosis Elimination Programme (NTEP) as the umbrella scheme, the BPaLM regimen (Bedaquiline+Pretomanid+Linezolid+Moxifloxacin) as a shorter 6-month oral treatment for drug-resistant TB, and the Pradhan Mantri TB Mukt Bharat Abhiyan for patient support, alongside Ni-kshay Sampark and the TB Mukt Panchayat Initiative.
• The spectrum of drug-resistant TB progresses from Rifampicin-Resistant TB (RR-TB) to Multidrug-Resistant TB (MDR-TB, resistant to both isoniazid and rifampicin), Pre-XDR-TB (MDR/RR-TB plus fluoroquinolone resistance), and XDR-TB (MDR/RR-TB plus fluoroquinolone and a second-line drug resistance).
• Antimicrobial Resistance (AMR) arises from poor hygiene, overuse/over-prescription of antimicrobials, and their addition to agricultural feed, and is tackled in India through the National Action Plan on AMR (NAP-AMR), the Red Line campaign, a separate Schedule H-1 for antibiotic sale, the Integrated One Health Surveillance Network for AMR, FSSAI antibiotic-residue limits in food, and the Chennai Declaration; bacteriophage ("phage") therapy is being explored as an antibiotic alternative.
• The One Health approach recognizes human, animal and environmental health as interdependent; the One Health Joint Plan of Action (2022-28) was launched by FAO, WOAH, WHO and UNEP and was a priority under India's G20 presidency, with India's initiatives including the One Health Support Unit (OHSU) under the Department of Animal Husbandry & Dairying, DBT's One Health Project for zoonotic disease surveillance, and the National Mission on Biodiversity and Human Wellbeing under PM-STIAC.
• Modern insulin for diabetes treatment is produced via recombinant DNA technology, typically expressed in E. coli or Saccharomyces cerevisiae, replacing earlier animal-extracted insulin.
• GLP-1 receptor agonists (a WHO-endorsed treatment for Type 2 diabetes and obesity) mimic the gut hormone GLP-1, secreted from intestinal L-cells, pancreatic alpha-cells and the CNS, to reduce appetite and stimulate insulin release; drugs in this class include Ozempic, Qsymia, Mounjaro and Zepbound.
• Research on the IL-35 protein suggests it may protect against Type 1 diabetes and other autoimmune diseases by regulating macrophage activation, T-cell proteins and regulatory B-cells.
• India regulates drug prices through the National Pharmaceutical Pricing Authority (NPPA) under the Ministry of Chemicals & Fertilizers, which fixes/revises prices of controlled bulk drugs under the Drugs (Prices Control) Order, 2013; related initiatives include the PM Jan Aushadhi Yojana, the Pharma Jan Samadhan Initiative, and PLI schemes for pharmaceuticals.
• India carries the world's largest burden of Neglected Tropical Diseases (NTDs) but has eliminated Guinea worm disease, Trachoma and Yaws; it became the third South-East Asian country after Nepal and Myanmar to eliminate Trachoma, per the 2012 London Declaration on NTDs targeting control/elimination/eradication of 10 NTDs by 2020; smallpox remains the only disease ever globally eradicated.
• Dietary fats fall into three categories: unsaturated fats (MUFA/PUFA, liquid at room temperature, beneficial for heart health), saturated fats (solid, no double bonds), and industrially-produced trans fats (partially hydrogenated vegetable oils that raise LDL and lower HDL); trans fats cause an estimated 540,000 deaths worldwide annually, driving WHO's recommendation to keep trans fat intake below 1% of energy and India's target of capping TFA content in foods below 2% through Trans Fat Free labelling and a heart-attack-rewind campaign.
• Oral Rehydration Solution (ORS), an emergency low-cost treatment for diarrhoea pioneered by Dr. Dilip Mahalanabis, works through co-transporters that use sodium and glucose to help the body reabsorb fluids and electrolytes across intestinal membranes.
• The Food Safety and Standards Authority of India (FSSAI), set up under the Food Safety and Standards Act, 2006 and administered by the Ministry of Health & Family Welfare, lays down science-based food safety standards, accredits certification bodies, monitors emerging food risks via rapid alert systems, and supports India's SPS compliance in international trade.
• Recent zoonotic/vector-borne disease concerns in India include Nipah virus (fruit bats as natural reservoir), Chandipura virus (linked to acute encephalitis syndrome outbreaks, spread by sandflies/mosquitoes/ticks), Lumpy Skin Disease in cattle (spread by blood-feeding insects, controlled via attenuated vaccines), and avian influenza H9N2 (rare human infections from poultry exposure) — reflecting the rising policy profile of the One Health approach in disease surveillance.
• India's cervical cancer burden (second most common cancer among Indian women) is being addressed through the indigenous Cervavac vaccine and HPV vaccination for girls aged 9-14, aligned with WHO's 90-70-90 elimination targets for 2030 (90% vaccinated by 15, 70% screened by 35 and 45, 90% of pre-cancer/invasive cases treated).
• Leprosy (Hansen's disease, caused by Mycobacterium leprae) is now treated in India under a revised three-drug WHO multidrug therapy regimen (dapsone, rifampicin, clofazimine) for paucibacillary cases, tracked via the Nikusth 2.0 case-management portal.
• India's genomic surveillance capacity spans INSACOG (SARS-CoV-2 genome surveillance) and InTGS (TB genome surveillance), run through a consortium of labs coordinated by MoH&FW, DBT, CSIR and ICMR.
• BHISHM (Bharat Health Initiative for Sahyog, Hita & Maitri) is a modular disaster-medicine system of RFID-tracked mini cube kits — 36 mini cubes form a mother cube, and 2 mother cubes form a full BHISHM Cube — with digital support in 180 languages, designed for rapid deployment in mass-casualty emergencies.
• U-WIN is a digital platform under India's Universal Immunization Programme that tracks every vaccination event for pregnant women and children (birth to 16 years) against 12 vaccine-preventable diseases, ensuring timely dose administration.
• Epigenome editing modifies gene expression by altering chemical markers (like DNA methylation or histone modification) that regulate transcription without changing the underlying DNA sequence, offering a potentially reversible alternative to direct gene editing for treating dysregulated gene expression.
• The Yamanaka Factors (Oct4, Sox2, Klf4, c-Myc) are transcription factors that reprogram adult somatic cells into induced pluripotent stem cells (iPSCs), with applications in regenerative medicine and drug testing.
• The DARE2ERAD TB programme (2022), run by the Department of Biotechnology, aims to sequence over 32,000 TB isolates to identify drug-resistance mutations and improve treatment outcomes.
• CEPI (Coalition for Epidemic Preparedness Innovations), founded in Davos in 2017 by the governments of Norway and India along with the Gates Foundation, Wellcome Trust and WEF, funds accelerated vaccine development against epidemic and pandemic threats.
• WHO's PRET (Preparedness and Resilience for Emerging Threats) Initiative groups pandemic-preparedness capacities by pathogen transmission mode (respiratory, vector-borne, foodborne), enabling shared systems across pathogen groups rather than disease-specific silos.
• Selenium is a natural trace element essential for health in small amounts, but becomes harmful when intake is roughly double the body's requirement; since soil selenium content directly affects levels in plant-based foods, an ICMR report linking elevated selenium in Indian wheat to hair loss highlights the food-safety/nutrition-monitoring challenge of trace-mineral contamination in the food chain.
