Core Statutory Rule (BLUF)

Under International Health Regulations (2005) Article 6, National IHR Focal Points must assess any unexpected or severe public health event within 48 hours using the Annex 2 decision instrument and notify WHO within 24 hours whenever any Box A disease occurs or at least two of the four Annex 2 risk criteria are met.

STATUTORY GATE · 48H ASSESS / 24H NOTIFY

Select the pathogen category first, then toggle the four statutory Annex 2 criteria to determine whether the National IHR Focal Point must notify WHO within 24 hours under Article 6.

1. Serious Public Health Impact
High case fatality, severe clinical presentation, rapid community spread, or potential overwhelm of hospital surge capacity.
2. Unusual or Unexpected
Atypical pathogen, unexpected season or geographic focus, unknown etiology, or suspected deliberate/accidental release.
3. Significant Risk of International Spread
Cross-border land/maritime corridor exposure, international aviation hub index case, or shared vector/food supply chain.
4. Significant Risk of Travel or Trade Restrictions
Historical border closures, export embargoes on livestock/food, or high international media/regulatory sensitivity.
SINGLE CRITERION MET (1 YES) · ARTICLE 8 CONSULTATION / 48H WATCH (1/4)
Continue 48-hour verification and EWARN triangulation

One criterion alone does not mandate Article 6 notification. Maintain active signal verification (Article 10) and initiate confidential Article 8 consultation if field evidence shifts.

Statutory 24-Hour and 48-Hour Reporting Matrix

Rapid epidemic intelligence fails when field units confuse internal verification deadlines with formal international notification clocks. Article 10 verification inquiries require an initial State Party response within 24 hours, whereas domestic Annex 2 assessment carries a 48-hour evaluation window followed immediately by a 24-hour notification duty once threshold criteria are satisfied.

IHR (2005) Article Operational Obligation Statutory Window Responsible Authority Verification Status
Article 5 Core surveillance and response capacity maintenance at local, intermediate, and national tiers Continuous (5-year capacity baseline) Ministry of Health / National Surveillance Unit BASELINE
Article 6 (Assess) Apply Annex 2 decision instrument to all unusual or severe public health events Within 48 hours of detection National IHR Focal Point (NFP) 48H GATE
Article 6 (Notify) Notify WHO by most efficient communications means following affirmative Annex 2 assessment Within 24 hours of assessment National IHR Focal Point (NFP) 24H MANDATORY
Article 7 Information-sharing during unexpected or unusual events regardless of origin or source Immediate upon evidence emergence State Party NFP CONTINUOUS
Article 8 Confidential technical consultation with WHO when Annex 2 threshold is inconclusive (1 criterion met) Concurrent with 48h assessment National IHR Focal Point (NFP) CONSULTATIVE
Article 10 Verify non-State / informal epidemic intelligence signals upon WHO request Initial response within 24 hours National IHR Focal Point (NFP) 24H VERIFY

Early Signal Verification Funnel (EWARN to Article 6)

Regional epidemic intelligence combines community rumors, Early Warning, Alert and Response Network (EWARN) clinic tallies, border screening manifests, and reference laboratory confirmation. Every raw signal progresses through four auditable triage gates before formal Public Health Emergency Operations Centre (PHEOC) escalation.

Frequently Asked Questions on IHR Annex 2 Triage

When is 24-hour WHO notification mandatory without scoring the four criteria?

Single cases of smallpox, poliomyelitis due to wild-type poliovirus, human influenza caused by a new subtype, and severe acute respiratory syndrome (SARS) listed in Annex 2 Box A always require WHO notification within 24 hours under Article 6, regardless of geographic containment.

Reference: WHO IHR (2005) Annex 2 Decision Instrument.

What should the National IHR Focal Point do if only one Annex 2 criterion is met?

When an event satisfies only one criterion at initial triage, mandatory Article 6 notification is not yet triggered. The Focal Point keeps the cluster under active 48-hour reassessment and may initiate a confidential technical consultation with WHO under Article 8.

Historical Citation Context: Outbreak and Public Health Event Portal (OPHEP)

Historically referenced under the anchor "Outbreak and Public Health Event Portal" by WHO Eastern Mediterranean Regional Office (EMRO) information resource pages and peer-reviewed surveillance literature (Buliva et al., Cogent Public Health 2023), OPHEP indexed high-threat pathogen outbreaks and response progress across the region.
