Epidemic intelligence principles

Epidemic intelligence is defined as the process of screening ,

filtering, validating, analysing and assessing potential public

health threats“ ”

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

Questions

1 - Quiz

What is the objective of Epidemic Intelligence ?

To early detect outbreaks

This is a wrong answer

To shortcut the traditional surveillance mechanisms


To enable timely response


All of the above

This is a correct answer

2 - Quiz

The first three stages of EI process are :

Scanning - Assessing -Communicating


Screening - Filtering -Validating

This is a correct answer

Detecting - Signaling -Monitoring


Screening - Detecting -Responding
