Why this matters now
Public health is a core GS-2 social-sector theme — the structure, the spending gap and the path to universal health coverage are perennial, sharpened by the pandemic’s lessons.
The three-tier structure
Health is largely a State subject. Rural care is delivered through a three-tier system: Sub-Centres and Health & Wellness Centres (primary), Primary Health Centres (PHCs) and Community Health Centres (CHCs) (secondary), and district hospitals and medical colleges (tertiary). The National Health Mission (NHM) is the umbrella programme.
Key challenges
- Low public health spending (~2% of GDP; target ~2.5%) and high out-of-pocket expenditure;
- Shortage of doctors, nurses and infrastructure, especially rural;
- Urban–rural and inter-state disparities;
- Double burden of disease (communicable + non-communicable);
- Weak primary care and preventive focus.
The way forward
Reforms aim at Universal Health Coverage (UHC) — strengthening primary care (Health & Wellness Centres), Ayushman Bharat (PM-JAY insurance + digital health), raising public spending, building the health workforce, and using digital health (ABDM, telemedicine) — with a shift from curative to preventive and promotive health.
