5. Multi-Dimensional Analysis

• Social: 2025 theme targeted maternal/newborn mortality — ~260,000 maternal deaths and ~2 million newborn deaths annually cited by WHO, underscoring persistent global health equity gaps. [S2]

• Plausible Mains stems:
• "Discuss the significance of the 'One Health' approach in addressing emerging global health challenges. How can India strengthen inter-sectoral coordination on these lines?" (GS-III)
• "Examine the role of the World Health Organization in shaping global maternal and child health priorities. Critically evaluate India's progress against these benchmarks." (GS-II/GS-III)

10. Common Errors / Trap Areas

• Confusing World Health Day (7 April) with World Health Assembly (WHO's annual governing body meeting, usually May) — distinct events.
• Mixing up annual themes across years (e.g., attributing the 2025 maternal-health theme to 2026, or vice versa).
• Assuming WHO Collaborating Centres Forum is a permanent recurring body — it is described as the inaugural edition in 2026.
• Misattributing the Lyon One Health Summit to WHO alone — it was hosted by the Government of France under its G7 Presidency, with WHO as a partner.
• Confusing WHO's regional offices (WPRO vs SEARO vs AFRO) when a question references region-specific guidance documents.
