international response.
Alert and Response Operations
Events that may constitute a
Public Health Emergency of International Concern need:
Detection
Verification
Risk assessment
Response
Verification of events
 Value of unofficial sources of information for
early alert
 WHO requests for verification of potential public
health events of international importance
 Member States provide initial reply within 24
hours and provision of information
 On-site assessment, when necessary
Event notification
 Any event that may constitute a Public Health
Emergency of International Concern (PHEIC)
 Within 24 hours of assessment
 By the most efficient means of communication
 Continue to provide WHO with detailed information
 Does NOT mean a real “PHEIC”
Disease List

 Smallpox, Poliomyelitis, human influenza (caused by a

 Utilization of the decision instrument:
 Cholera, plague, viral haemorrhagic fevers, yellow

 Diseases of regional concern: dengue fever,
meningococcal diseases…
Decision Instrument
Criteria for assessment
1. Is the public health impact of the event serious?

4. Is there a significant risk of international travel or trade
restrictions?
Answering "yes" to any two of the criteria
requires a member state to notify WHO
Is the event serious?

No

notified
at this
stage.
Notify the event under the International Health Regulations
Is the event serious?
 Morbidity and mortality
 Does the event have potential for high impact?
 Population at risk
 Cases in health staff; highly infectious
 Factors affecting response e.g. war, natural

 High population density
 Immediate or potential need for external
assistance
Is the event unexpected?
 Is the cause of the event unknown?
 Are the circumstances unusual?
 Cases worse than usual
 Treatment failures
 Event unusual for place/season
 Caused by eliminated/eradicated agent

Is the event likely to spread internationally?
 Similar cases in other countries where it was
unexpected?
 Factors alerting to cross-border implications?
 Caused by epidemic-prone organism
 Source suspected/ known to be related to food
import/export
 Index case with international travel history
 In area with international tourism/ traffic, person or
goods
 In border areas with limited capacity for control
Is event likely to result in international travel
and trade restrictions?
 Similar events previously led to restriction
on travel/ trade?

goods known to be imported or exported?
 In area with international tourism?
 Attracted media attention?
