What were the key lessons from COVID-19 in India?

COVID-19 was India's biggest public health event in independent history. KEY NUMBERS: (1) ~4.5 CRORE confirmed cases (May 2024); ~5.3 LAKH deaths officially (likely substantial undercount per WHO/Lancet estimates of 4.7M); (2) ~220 CRORE vaccine doses administered (largest vaccination programme in human history); (3) ~₹13 LAKH CRORE estimated economic loss in 2020-21 GDP. KEY LESSONS: (1) DEFICIT in HEALTH INFRASTRUCTURE — Insufficient hospital beds, ICUs, ventilators, oxygen supply during Delta wave April-May 2021 (~17 lakh died officially during second wave; estimates higher); (2) WEAK SURVEILLANCE — IDSP couldn't track community transmission adequately; (3) MIGRANT WORKER CRISIS — exodus during March-April 2020 lockdown exposed gaps in informal worker protection; (4) STATE-CENTRE COORDINATION — Disaster Management Act invoked first time for a health emergency; National Health Mission strained; (5) SUCCESS — RAPID VACCINE DEVELOPMENT (Covishield, Covaxin, Corbevax, ZyCoV-D); CO-WIN platform (built on India Stack); ECONOMIC RELIEF (PMGKAY 5 kg free foodgrains); ATMANIRBHAR BHARAT package; (6) DIGITAL HEALTH — ABDM (Ayushman Bharat Digital Mission) launched Sep 2021; ABHA health IDs; e-Sanjeevani teleconsultation; (7) NEED for ONE HEALTH approach — addressing zoonotic disease transmission (COVID likely from animal); (8) HEALTH SYSTEM RESILIENCE — Importance of public health infrastructure, primary care, district level. POLICY RESPONSE: (1) PM-ABHIM 2021 — ₹64,180 crore over 5 years; (2) National One Health Mission proposed; (3) NIDDM (National Institute for Development of Disaster Medicine) proposal; (4) IDSP being upgraded to IHIP; (5) Strengthened ICMR; (6) Strengthened NCDC; (7) Universal Vaccination architecture (UVI) reform. COVID also showed that India can mount the LARGEST public health response in human history — but the response was uneven across STATES and over WAVES.

What is PM-ABHIM (PM Ayushman Bharat Health Infrastructure Mission)?

PM-ABHIM — PRADHAN MANTRI AYUSHMAN BHARAT HEALTH INFRASTRUCTURE MISSION — was approved by Union Cabinet on 15 SEPTEMBER 2021 and launched on 25 OCTOBER 2021 by PM Modi. ANNOUNCED IN BUDGET 2021-22; LARGEST PAN-INDIA HEALTH INFRASTRUCTURE SCHEME ever. OUTLAY: ₹64,180 CRORE over 5 years (2021-22 to 2025-26). OBJECTIVE: Strengthen PUBLIC HEALTH INFRASTRUCTURE at PRIMARY, SECONDARY, TERTIARY levels and DISEASE SURVEILLANCE. SIX COMPONENTS: (1) BUILDING-LEVEL BLOCK PUBLIC HEALTH UNITS (BPHUs) — 17,788 BPHUs supporting Sub-Centres, PHCs; (2) CRITICAL CARE HOSPITAL BLOCKS — 600+ districts to get dedicated CRITICAL CARE BLOCKS (50-100 beds each); (3) STRENGTHENING DISTRICT PUBLIC HEALTH LABORATORIES — modern testing; (4) NATIONAL CENTRE FOR DISEASE CONTROL (NCDC) EXPANSION + 5 REGIONAL NCDCs (BHUBANESWAR, BENGALURU, KOLKATA, MUMBAI, GUWAHATI); (5) INTEGRATED HEALTH INFORMATION PLATFORM (IHIP) — replacing IDSP for real-time surveillance; (6) BIO-SAFETY LEVEL III LABORATORIES in every state; BSL-4 LAB at NCDC (only second in India after NIV Pune). OTHER COMPONENTS: (1) METROPOLITAN PUBLIC HEALTH UNITS in major cities; (2) BLOCK PUBLIC HEALTH UNITS in 730 blocks; (3) Strengthening AT POINTS of ENTRY (33 airports, 11 sea ports, 7 land crossings) for international health emergency response; (4) HEALTH EMERGENCY OPERATION CENTRES (HEOC) at state level. INTEGRATION: PM-ABHIM works alongside Ayushman Bharat (PMJAY + Health & Wellness Centres now Ayushman Arogya Mandir), Ayushman Bharat Digital Mission (ABDM), National Health Mission. ROLE in PANDEMIC PREPAREDNESS: (1) Surveillance backbone via IHIP; (2) Diagnostic capacity at district level; (3) Critical care surge capacity; (4) Bio-safety lab network; (5) Trained workforce. PROGRESS (2024-25): ~10,000 BPHUs operational; 200+ CCBs constructed; NCDC expansion underway; some states (KE, TN, MH) ahead; some (BR, JH, MP) lagging. PM-ABHIM is INDIA's PRINCIPAL pandemic preparedness investment.

What is the One Health approach in India?

ONE HEALTH is an INTERDISCIPLINARY APPROACH that RECOGNISES the INTERCONNECTION between HUMAN HEALTH, ANIMAL HEALTH, and ENVIRONMENTAL HEALTH. ~75% of new emerging infectious diseases (Ebola, SARS, MERS, COVID-19, monkeypox, Nipah, H5N1 avian influenza) are ZOONOTIC (transmitted from animals to humans). PRINCIPLE: 'one health for humans, animals, plants, and ecosystems' — endorsed by WHO, FAO, OIE (World Organisation for Animal Health), UNEP under the QUADRIPARTITE COLLABORATION 2022. INDIA's ONE HEALTH FRAMEWORK: (1) NATIONAL ONE HEALTH MISSION — announced 2023; coordination among Ministry of Health, Ministry of Agriculture, Animal Husbandry, Environment, Forest; (2) NATIONAL INSTITUTE OF ONE HEALTH (NIOH), NAGPUR — under ICMR; (3) NATIONAL ONE HEALTH ADVISORY COUNCIL; (4) DECENTRALISED — State One Health units; (5) ZOONOTIC DISEASE SURVEILLANCE — integration of human + animal + environmental data; (6) JOINT INVESTIGATION TEAMS for zoonotic outbreaks. KEY PROGRAMMES: (1) NATIONAL ANIMAL DISEASE CONTROL PROGRAMME (NADCP) — for foot & mouth, brucellosis; (2) INTEGRATED DISEASE SURVEILLANCE PROGRAMME (IDSP) — expanding to include zoonotic alerts; (3) JOINT NIPAH virus response in Kerala; (4) ANTIMICROBIAL RESISTANCE (AMR) National Action Plan 2017; (5) Wildlife disease surveillance under Wildlife Institute of India; (6) WHO-FAO joint initiatives. IMPLEMENTATION CHALLENGES: (1) MINISTERIAL SILOS — Health, Agriculture, Environment historically operate separately; (2) DATA SHARING limited; (3) STATE-LEVEL One Health capacity uneven; (4) FUNDING for integrated approach modest. INTERNATIONAL: India is part of QUAD HEALTH SECURITY COOPERATION; WHO PANDEMIC ACCORD negotiations 2022-26; G20 health priorities under India's 2023 presidency emphasised One Health. RECENT EVENTS: (1) NIPAH virus outbreaks in Kerala (2018, 2021, 2023); (2) Crimean-Congo Hemorrhagic Fever Gujarat; (3) BIRD FLU outbreaks; (4) ANTHRAX outbreaks. One Health is becoming central to India's pandemic preparedness — but operational integration is still being built.

What is IDSP and the proposed IHIP?

INTEGRATED DISEASE SURVEILLANCE PROGRAMME (IDSP) was launched in NOVEMBER 2004 by Ministry of Health with World Bank assistance to STRENGTHEN DISEASE SURVEILLANCE in INDIA. It is the foundation of India's epidemic detection capability. KEY FEATURES: (1) WEEKLY REPORTING from PUBLIC and PRIVATE health facilities; (2) Reports ~30+ DISEASES (cholera, dengue, malaria, chikungunya, encephalitis, etc.); (3) EARLY WARNING SIGNALS for outbreak detection; (4) STATE/DISTRICT SURVEILLANCE UNITS; (5) DATA AGGREGATION at central level — National Centre for Disease Control (NCDC). ARCHITECTURE: (1) S-SYNDROMIC reporting (symptom-based) by health workers at community; (2) P-PRESUMPTIVE reporting from doctors/PHCs; (3) L-LABORATORY confirmed reporting. ACHIEVEMENTS: (1) DETECTED multiple outbreaks; (2) FOUNDATION for COVID-19 RESPONSE infrastructure; (3) ~95% of districts covered; (4) Trained ~12 lakh health workers in surveillance. LIMITATIONS DURING COVID: (1) INADEQUATE genomic surveillance; (2) Limited PRIVATE SECTOR integration; (3) Reporting delays; (4) Community surveillance gaps; (5) Inter-state coordination weak; (6) Limited integration with animal/environmental data. INTEGRATED HEALTH INFORMATION PLATFORM (IHIP) is the UPGRADE — being rolled out under PM-ABHIM. KEY FEATURES: (1) DIGITISED, REAL-TIME reporting; (2) INTEROPERABILITY with ABDM (Ayushman Bharat Digital Mission), NIKSHAY (TB), Co-WIN, e-Sanjeevani; (3) AI/MACHINE LEARNING for early signal detection; (4) GIS-BASED outbreak mapping; (5) MOBILE APP for community reporting; (6) Integration with animal health (ONE HEALTH); (7) GEOLOCATION of cases; (8) ~33 districts pilot completed 2022-23; ROLLOUT NATIONWIDE 2024-26. FUTURE: India is investing in a NATIONAL HEALTH GENOMIC SURVEILLANCE network (INSACOG — Indian SARS-CoV-2 Genomics Consortium expanded to broader pathogens); WASTEWATER SURVEILLANCE in major cities (pioneered during COVID; now studying poliovirus, HIV, dengue). IHIP + INSACOG + WASTEWATER together form INDIA's NEXT-GENERATION SURVEILLANCE STACK.

What is the WHO Pandemic Accord and India's policy direction?

WHO PANDEMIC ACCORD (sometimes called Pandemic Treaty) is being negotiated since 2022 by WHO MEMBER STATES under the INB (Intergovernmental Negotiating Body). DRAFT 4 was being finalised May 2024 at the World Health Assembly. INDIA is an ACTIVE PARTICIPANT through the WHO South-East Asia Region. KEY ELEMENTS UNDER NEGOTIATION: (1) GOVERNANCE — Conference of Parties, Implementation Body; (2) EQUITY in vaccine/therapeutics/diagnostics ACCESS — addressed through PABS (Pathogen Access and Benefit Sharing) — countries share pathogens, get fair access to resulting products; (3) ONE HEALTH approach to pandemic prevention; (4) Strengthening WHO emergency rules under IHR (International Health Regulations 2005); (5) TECHNOLOGY TRANSFER and intellectual property sharing during health emergencies; (6) PANDEMIC SURVEILLANCE network; (7) FINANCING mechanism. INDIA's POSITION: (1) Support for EQUITABLE access to vaccines and therapeutics; (2) PROTECT national autonomy on health policy decisions; (3) STRENGTHENING SOUTHERN voice in international health diplomacy; (4) EXPANSION of generic drug capacity; (5) Support for technology transfer. INTERNATIONAL HEALTH REGULATIONS (IHR) 2005 — Already binding on India; require notification of public health events of international concern (PHEIC) within 24 hours; was activated for COVID 30 January 2020. INDIA's PANDEMIC POLICY DIRECTION 2024-26: (1) PM-ABHIM implementation; (2) National One Health Mission scale-up; (3) IHIP rollout nationwide; (4) Pandemic-specific financing under DM Act; (5) National Centre for Disease Control expansion + 5 regional NCDCs; (6) BSL-4 lab at NCDC (only second in India after NIV Pune); (7) Vaccine R&D capacity through BIRAC, ICMR-NIV, BHARATBIOTECH, SERUM INSTITUTE; (8) National Institute for Development of Disaster Medicine proposal; (9) HEALTH EMERGENCY OPERATION CENTRES at state level; (10) PUBLIC HEALTH SURGE FORCE proposal (analogous to NDRF for health). CHALLENGES: (1) ENFORCEMENT of obligations; (2) WORKFORCE — India has only ~1 epidemiologist per 200,000 population; (3) FINANCING — public health investment ~2.1% of GDP vs 2.5% target; (4) CENTRE-STATE coordination during crises; (5) Private sector integration; (6) Quality of district health systems.

Pandemic Preparedness in India post-COVID — PM-ABHIM, One Health | UPSC

Why this matters now

COVID-19 was the largest public health event in independent India's history. The 2024 World Health Assembly is finalising the WHO Pandemic Accord. Climate change is driving zoonotic spillover. Bird flu (H5N1) is the next-most-likely candidate. Three reasons this closes the Disaster Management cluster. First, PM-ABHIM (₹64,180 crore over 5 years) is the largest pan-India public health infrastructure investment ever. Second, the One Health framework is now being operationalised in India after years of being a slogan. Third, the WHO Pandemic Accord and IHR 2005 amendments are reshaping the international health architecture in real time.

COVID-19 — the lessons

What India got right

Rapid vaccine development — Covishield, Covaxin, Corbevax, ZyCoV-D;
CoWIN platform — built on India Stack;
Largest vaccination drive in history — 220 crore doses;
Economic relief — PMGKAY 5 kg free foodgrains; Atmanirbhar Bharat package;
ABDM launched September 2021 — 70 crore ABHA IDs;
e-Sanjeevani — 50+ crore teleconsultations.

What broke

Health infrastructure deficit — beds, ICUs, ventilators, oxygen during Delta wave April-May 2021;
Weak surveillance — IDSP couldn't track community transmission;
Migrant worker crisis — March-April 2020 lockdown exodus;
Excess deaths — Lancet 2022 estimate ~4.7 million (vs official 5.3 lakh);
State-Centre coordination strained;
Private sector integration uneven.

PM-ABHIM — the post-COVID rebuild

Pradhan Mantri Ayushman Bharat Health Infrastructure Mission, approved 15 September 2021. Outlay ₹64,180 crore over 5 years (2021-22 to 2025-26). Largest pan-India public health infrastructure scheme ever.

Six components

Building-level Block Public Health Units (BPHUs) — 17,788 BPHUs supporting Sub-Centres and PHCs;
Critical Care Hospital Blocks — 600+ districts to get dedicated 50-100 bed CCBs;
District public health labs — modernised testing;
NCDC expansion + 5 regional NCDCs — Bhubaneswar, Bengaluru, Kolkata, Mumbai, Guwahati;
Integrated Health Information Platform (IHIP) — replacing IDSP;
BSL-3 labs in every state; BSL-4 at NCDC — only second in India after NIV Pune.

Additional components: Metropolitan Public Health Units; 730 block-level PHUs; strengthening points of entry (33 airports, 11 sea ports, 7 land crossings); state Health Emergency Operation Centres (HEOC).

Progress (2024-25): ~10,000 BPHUs operational; 200+ CCBs constructed; NCDC expansion underway; KE/TN/MH ahead; BR/JH/MP lagging.

One Health — the integrated approach

~75% of new emerging infectious diseases are zoonotic — Ebola, SARS, MERS, COVID-19, monkeypox, Nipah, H5N1 avian influenza. The One Health approach recognises that human health, animal health, and environmental health are interconnected.

Endorsed by WHO, FAO, WOAH (formerly OIE), UNEP under the Quadripartite Collaboration 2022.

India's framework

National One Health Mission — announced 2023; cross-ministerial coordination;
National Institute of One Health (NIOH), Nagpur — under ICMR;
State One Health units;
Zoonotic disease surveillance integration;
Joint investigation teams for outbreaks;
AMR National Action Plan 2017;
Wildlife disease surveillance under WII.

Recent events: Nipah outbreaks in Kerala (2018, 2021, 2023); Crimean-Congo Hemorrhagic Fever Gujarat; bird flu outbreaks; anthrax outbreaks.

IDSP & the IHIP upgrade

Integrated Disease Surveillance Programme launched November 2004 with World Bank assistance. Reports ~30+ diseases. Three reporting layers: S (syndromic), P (presumptive), L (laboratory-confirmed).

Limitations exposed by COVID: inadequate genomic surveillance; weak private sector integration; reporting delays; community gaps; inter-state coordination weak; no animal/environmental integration.

Integrated Health Information Platform (IHIP) — the upgrade under PM-ABHIM:

Digitised, real-time reporting;
Interoperability with ABDM, Nikshay (TB), CoWIN, e-Sanjeevani;
AI/ML for early signal detection;
GIS-based outbreak mapping;
Mobile app for community reporting;
One Health integration;
33 districts pilot completed 2022-23; nationwide rollout 2024-26.

INSACOG & wastewater surveillance

Indian SARS-CoV-2 Genomics Consortium (INSACOG) — being expanded to broader pathogens. Wastewater surveillance, pioneered during COVID, now studying poliovirus, HIV, dengue in major cities.

BSL-3, BSL-4 labs and NCDC expansion

BSL-3 lab in every state under PM-ABHIM — for high-containment pathogens;
BSL-4 lab at NCDC — only second in India after NIV Pune;
NCDC expansion + 5 regional NCDCs (Bhubaneswar, Bengaluru, Kolkata, Mumbai, Guwahati);
NIV Pune — flagship virology institute; isolated SARS-CoV-2 first in India;
ICMR network of 27 institutes.

Workforce gap

India's epidemiology workforce is one of the smallest globally — ~1 epidemiologist per 200,000 population (US has ~1 per 30,000). Key initiatives:

Field Epidemiology Training Programme (FETP) — three-tier; ~200 graduates a year;
Public health cadre proposal — pending;
School of Public Health expansion;
Public Health Surge Force proposal (analogous to NDRF for health).

WHO Pandemic Accord

Under negotiation since 2022 by the Intergovernmental Negotiating Body (INB). Draft 4 was finalised May 2024 at the World Health Assembly. India is active through the WHO South-East Asia Region.

Key elements

Governance — Conference of Parties; Implementation Body;
Equity in vaccine/therapeutics/diagnostics access — through PABS (Pathogen Access and Benefit Sharing);
One Health approach to prevention;
Strengthening WHO emergency rules under IHR 2005;
Technology transfer and IP sharing during emergencies;
Pandemic surveillance network;
Financing mechanism.

India's position

Equitable access to vaccines and therapeutics;
Protect national autonomy on health policy;
Strengthen Southern voice;
Expand generic drug capacity;
Support technology transfer.

IHR 2005 — already binding; require notification of PHEIC (Public Health Emergency of International Concern) within 24 hours; activated for COVID 30 January 2020.

Epidemic Diseases Act 1897 — the colonial law that ran COVID

The Epidemic Diseases Act 1897 — a 4-section colonial law — was the legal foundation for the COVID-19 lockdown. Limitations:

No definition of "epidemic";
No public health emergency framework;
No federal coordination mechanism;
No vaccination/quarantine rights regime;
Limited penalty provisions (later supplemented by DM Act 2005 + Epidemic Diseases (Amendment) Ordinance 2020 to protect healthcare workers).

A comprehensive Public Health Emergency Act has been recommended by multiple committees; still pending.

Policy direction 2024-26

PM-ABHIM full implementation;
National One Health Mission scale-up;
IHIP nationwide rollout;
5 regional NCDCs operational;
BSL-4 at NCDC operational;
Public health workforce expansion;
Public Health Emergency Act enactment;
WHO Pandemic Accord ratification and implementation;
Climate-disease modelling;
Wastewater surveillance scale-up.

"COVID-19 was the test India barely passed. The next pandemic — likely an avian-influenza spillover or an antimicrobial-resistance crisis — will be the test India must prepare for now. PM-ABHIM, One Health, IHIP, BSL-4 — these are the architecture. The challenge is the workforce, the financing, and the political will to invest before the next emergency." — paraphrasing the Lancet Citizen's Commission on Reimagining India's Health System 2021
