Current context - 21st Century
Emergence of new or newly recognised
pathogens (e.g. Avian influenza, Ebola,
Marburg, Nipah, SARS)
Resurgence of well characterised outbreakprone diseases (e.g. cholera, dengue,
measles, meningitis, shigellosis, and
yellow fever)
Accidental or deliberate release of a
biological agent (e.g. BSE /v CJD, anthrax)

The 21st Century - Approach
Preparedness is the key
A generic approach (flexible systems)
Crisis management must be…
Multi-sectoral
Multilevel
Inclusive networks
Animal-human surveillance
New technologies

Global threat - global response
This global threat requires a global response to
– investigate, characterise and assess the threat
– reduce human suffering
– contain national/international spread
– minimize impact on travel and trade
WHO brings partners together to focus global
resources on outbreaks!

CSR Alert and Response Operations
 Detection, verification, characterisation, assessment and
response to epidemic disease threats
 Standardised processes and operational platform (intelligence, verification,
stockpiling, logistics, partner mobilisation-GOARN)
 Involves multiple Programmes and Departments (ARO, GIP, LYO, RAD,
PCS, FOS, ZFK, CPE, EPI, Polio, HAC)
 Requires deep operational co-ordination with Regional Offices and WHO
Country Offices
 May require involvement of Directors Office, MSU, IT, Travel,
Security…DGO !
 3 Teams
 Assessment and Field Operations (AFO)
 Epidemic Readiness and Mass Interventions (ERI)
 Emerging and Dangerous Pathogens (EDP)

Outbreak Response Operations
 “Routine” Events –
 Continual co-ordination required between disease focal point and ARO during
outbreak alert and response process
 Continuous work with “communications” group
 Major events
 require an even deeper collaboration with ARO providing overall event
management co-ordination and the disease-specific programme focusing on
the public health/scientific issues.
 Generic surge capacity may be required at HQ by ARO and in the main has
come from the Lyon teams and external partners in GOARN
 Senior WHO staff may be needed as field teams leaders or mission specialists
(Lyon have provided support on a number of occasions)
 Requires involvement of Directors Office, MSU, IT, Travel, Security
EVERY PROGRAMME HAS A STAKE IN OUTBREAK RESPONSE !

GOARN is a global technical
partnership, coordinated by WHO:
– to provide rapid international
multi-disciplinary technical
support for outbreak response

Primary Aims
 Assist countries with disease control
efforts by ensuring appropriate technical
support to affected populations rapidly.
 Investigate and characterize events and
assess risks of rapidly emerging epidemic
disease threats.
 Sustain containment and control of
outbreaks: contribute to national outbreak
preparedness by ensuring that acute
responses contribute to sustained
containment of the epidemic threat.

Other areas of Essential
Collaboration
 Focusing more energy on “RESPONSE” capacity strengthening
 Developing response protocols for deliberate epidemics
 Regional multidiciplinary laboratory networks (response,
biosafety, quality assurance, capacicy strengthening)
 Research during outbreaks (e.g. Ebola, Influenza, SARS)
 Safe clinical management during outbreaks
 Mass gathering events (CSR-wide policy and guidance)

SARS - lesson for global response
Communication is key
– highest political commitment required
– between WHO and countries, with the public and the media
– multi-sector event (health, veterinary, food safety, economy,
transport, etc.)
Evidence-based action/transparency/confidence
– efficient alert and response system in all countries
– rapid sharing of data/information
Global partnership
– globalization – no borders
– no country can do it alone, global resources needed rapidly

Communications
Dissemination of information
to a global audience:
– Disease outbreak news
– Outbreak Verification list
– Active media interface
Operational Readiness
– confidential communication
with GOARN

Advocacy: strategy
Strategy:
“Give the right message to the right people at
right time with the intended effect”
• message: identifiable image; consistent;
adaptable
• delivery: be ready; be opportunistic; be timely
• audience: customize message; use SAC

Revision proposals and disease
surveillance

Revised IHR will NOT establish a surveillance system for
specific diseases – (cf. current IHR)

Establish mechanism for early warning of events that
require an immediate response in order to prevent spread
of disease or risk of disease

Disease based surveillance is important at both national
and international levels but is not helped by international
legal obligations
E P I D E M I C
A L E R T

R E S P O N S E
Current Context
Countries expect faster response:
– more systematic interventions
– more defined contribution to sustained
control
Partners expect a stronger operational platform
in the field, and the opportunity to engage
in consultations from home institutions.
