International Health Regulations
WHO's binding international legal framework governing member state obligations during public health emergencies of international concern.
The International Health Regulations framed the 2026 Bundibugyo Ebola response: WHO declared a PHEIC under Article 12 on 17 May without first convening its Emergency Committee, and the United States ignored the committee's 22 May advice against travel bans.

Pandemics and BiosecurityBackground
The International Health Regulations are the binding legal framework, administered by the World Health Organization, for how states prevent, detect and respond to public health risks that can cross borders. They remain the main operative legal instrument in an outbreak while the WHO Pandemic Agreement waits on its unfinished annex. WHO also issues standing recommendations under them, and in 2026 it extended its standing mpox recommendations to August 2027.
The 2005 revision replaced a 1969 text that covered only a short list of quarantinable diseases. It created the Public Health Emergency of International Concern (PHEIC) and required states to keep core surveillance and response capacities. Amendments adopted by the 77th World Health Assembly in June 2024 entered into force in mid-2025. They added a Pandemic Emergency tier above the PHEIC, clarified Temporary Recommendations, strengthened equity provisions and set new reporting duties for pathogens of pandemic potential. An Emergency Committee advises the Director-General on declarations and recommendations.
The regulations bind 196 states parties, including every WHO member state, and compliance is reviewed through Joint External Evaluations. Enforcement rests on diplomatic pressure, peer review and reputation rather than sanctions. That leaves a lasting gap between written obligations and state behaviour, above all on travel and trade restrictions.
The Ebola emergency exposed its enforcement gap
On 17 May 2026 Director-General Tedros declared a PHEIC for Bundibugyo Ebola in DR Congo and Uganda before convening the Emergency Committee, a shortcut Article 12 allows when delay would cause harm. He judged the outbreak short of the Pandemic Emergency tier added by the 2024 amendments.
The committee met on 19 May and confirmed the PHEIC. Its Temporary Recommendations, issued on 22 May, called for exit screening, 21-day contact tracing and safe burials, and advised against travel or trade restrictions. The United States had already barred nationals of DR Congo, Uganda and South Sudan on 18 May, and faced no formal consequence. On 28 May the US, Mexico and Canada added Ebola screening at World Cup venues, also against WHO advice.
