Examine the role of the International Health Regulations and the PHEIC mechanism in managing cross-border epidemics. How far are they effective in fragile, conflict-affected regions?

The International Health Regulations (IHR), 2005 are a legally binding WHO instrument. They require states to detect, report and respond to public health risks while avoiding needless disruption of travel and trade. Their strongest tool is the Public Health Emergency of International Concern (PHEIC). The 2026 Bundibugyo Ebola outbreak in the DR Congo shows that the IHR regime coordinates well across borders but falters on the ground in conflict zones.

Role of IHR and PHEIC

• Expert-led declaration: the IHR Emergency Committee met on 18 August 2026 and advised that the outbreak remains a PHEIC. Temporary recommendations to States Parties followed [2].
• Shared situational data: WHO's Disease Outbreak News gives every country the same picture, such as a 48.1% crude fatality ratio in the DRC [2].
• Protecting travel and trade: WHO advises against travel or trade restrictions and calls for surveillance and point-of-entry screening instead [1]. This means countries are not punished for reporting openly.
• Mobilising resources: the ICG released 70,000 vaccine doses, 20,000 for a Phase 3 trial and 50,000 for frontline workers, welcomed jointly by WHO and Africa CDC [3].
• Containment where capacity exists: Kenya traced all 135 contacts of its imported cases and screened 709,093 travellers [1].

Effectiveness in fragile, conflict-affected regions

• Broken contact tracing: the DRC follows up only 79.7% of contacts, against a 95% target [1]. Each missed contact is a gap that ring vaccination cannot close.
• Late detection: 307 of 482 recent deaths happened in communities, not treatment centres [1].
• Insecurity and distrust: Tedros called Ituri and North Kivu "highly insecure", with more than 100,000 people newly displaced and deep distrust of outside authorities [4].
• No enforcement and thin funding: IHR recommendations depend on state capacity, and WHO reports "critical funding gaps" [1].
• Spillover: imported cases in Kenya and Nigeria show that weak links put the whole region at risk [1].

Verdict: the IHR and PHEIC work well as a norm-setting and coordination framework. In fragile states they are only partly effective, because they cannot replace a functioning health system or physical security.

The IHR regime has made the global response faster and more transparent, but rules alone cannot reach conflict zones. The way forward is to fund IHR core capacities, combine humanitarian and health operations, build community trust, and put the 2024 IHR amendments into practice. These steps support SDG 3.d on early warning and health-risk management, so that the PHEIC framework protects people wherever outbreaks start.
