Epidemic intelligence principles
Epidemic intelligence is defined as the process of screening ,
filtering, validating, analysing and assessing potential public
health threats“ ”

Purpose of EI
Risk detection/
monitoring
Risk assessment
Risk management
Detect and monitor information and
health threats
•Investigate alerts
• Assess risks
•Provide options for response
•Issue scientific advice
Implement control measures
Issue scientific advice

The Epidemic Intelligence Framework
Standard surveillance
Indicator-based surveillance (IBS)
Event monitoring
Event-based surveillance (EBS)
• Aiming the detection of unusual disease
patterns through analysis and interpretation of
common indicators (number of cases
compared to same period of last years,
proportions, rates, trends…)
• Aiming the detection of public health events
through the capture of ad-hoc information from
official and unofficial sources
This tutorial will focus moslty on Event based surveillance
• Also for unknown or unconfirmed diseases• For known diseases

Objective of EI
- to speed up the detection of potentialhealth threats
- to provide a timely response

Items of interest
Signals
Events
Threats
incidents/cases/clusters/outbreaks
- detected in one or several
countries
- Do not have (yet) a public
health impact in the target
population
OR
- Are not unexpected
Definitions
Events are
cases/clusters/outbreaks/incidents
occurring in one or several countries
and that have or may have a public
health impact and be of significance
for your target population
They are unusual or unexpected.
Threats are events that
fulfil EWRS criteria, or
IHR criteria , or are
considered of high
relevance for your target
population due to high
media attention or ad-
hoc factors
Here the green circles should open pop up with the examples
