Examine the role of the World Health Organization under the International Health Regulations (IHR) 2005 in managing post-disaster health emergencies. How effective is the current framework?

The IHR (2005) is a legally binding instrument among 196 States Parties to prevent and control the international spread of disease without unnecessary interference in travel and trade [1]. Post-disaster settings test it hardest, as Venezuela's 2026 earthquakes showed, with WHO warning of measles, diphtheria and dengue outbreaks in crippled hospitals [3].

WHO's role under the IHR framework

• Surveillance and notification: States must notify WHO of events that may constitute a Public Health Emergency of International Concern (PHEIC); WHO may also act on non-State information [1].
• Risk assessment and declaration: an Emergency Committee advises, and the Director-General declares a PHEIC and issues Temporary Recommendations [2].
• Capacity building: WHO monitors 15 core capacities through the annual States Parties Self-Assessment (SPAR) tool [4].
• Operational response: field verification and supply. In Venezuela, WHO verified 21 health facilities across Caracas, La Guaira, Miranda and Falcón and released US$1.5 million from its Contingency Fund for Emergencies [3].

Strengths of the framework

• Near-universal participation — 196 of 197 States Parties submitted SPAR reports, giving a common global baseline [4].
• Speed of technical deployment: a field hospital and medical teams were mobilised through PAHO within days of the Venezuela quakes [3].

Limitations

• No enforcement mechanism — compliance rests on State self-reporting, so casualty undercounting or restricted field access blunts response [3].
• Self-assessment overstates readiness; declared capacity often collapses under real stress.
• Disease-centric design: sudden-onset disasters that wreck health systems fall outside the PHEIC trigger.
• Chronic underfunding — the WHO Health Emergency Appeal 2026 seeks nearly US$1 billion for 36 emergencies against shrinking humanitarian finance [5].

The IHR therefore works well as a normative and coordinating architecture, but weakly as an enforcement one. The 2024 IHR amendments, which add a "pandemic emergency" tier and require a National IHR Authority, point the way forward [6]. Sustained financing, verified rather than self-declared capacity, and integration with disaster-risk reduction would let the IHR deliver on its founding promise of collective global health security.
