2. Introduction
• Early warning of outbreaks
• prediction of spread
• dealing with a disease epidemic in its early
stages
• infection does not recognize geographical nor
species borders
• international level FAO, OIE and WHO
• national and regional level

3. Objectives of forecasting or Global
Early warning and response system
( GLEWS)
• To study transmission and to to prevent
spread of epidemic diseases
• To monitor the effectiveness of disease
control campaigns
• To prepare for Emergency situations

4. Definition of GLEWS
The Global Early Warning and Response System (GLEWS) is a joint system
that builds on the added value of combining and coordinating the alert
and response mechanisms of OIE, FAO and WHO for the international
community and stakeholders to assist in prediction, prevention and
control of animal disease threats, including zoonoses, through sharing of
information, epidemiological analysis and joint field missions to assess and
control the outbreak, whenever needed

6. International level Existing Early
Warning Systems
• OIE:
• Member Countries
• World Animal Health Information Database (WAHID)
• World Animal Health Information System (WAHIS)
• Global Framework for Transboundary Animal Diseases (GF-TADs)
• FAO:
• EMPRES priority programme
• Global Framework for Transboundary Animal Diseases (GF-TADs)
• WHO:
• The Global Outbreak Alert and Response Network (GOARN)
The three organizations use complementary and partly overlapping
sources of information
