SE Asia Early Warning & Response
A collaborative early warning and response space for latest health-related events in SE Asia
Overview


Infectious disease events represent substantial
morbidity, mortality, and socio-economic impact in SE
Asia
The infectious disease event reporting in SE Asia was of:
Low socioeconomic disruption (83%),
 High socioeconomic disruption (17%); with indicators of a:

potential sociological crisis (16%), and
 disaster (0.6%)

Overview

Information Sources



ProMed MBDS
Veratect
From September 1, 2008 to February 27, 2009
 998 near real-time reports on



46 infectious diseases that effect humans or animals
Myanmar, Thailand, Laos, Cambodia, and Vietnam
220 provinces, 239 districts, and 14 cities
Approximations of Epidemiological
Features
The majority of reporting was related to possible epidemic situations. This
information is available for each report in Evolve and thus represents
granularity down to the lowest geographic unit presented in a given report
and by disease event in SE Asia
Approximations of Epidemiological
Features

What diseases were reported to have affected
different age groups in SE Asia

Reports of mortal outcomes for all age groups

Which of the infectious disease events presented as

single cases, apparently localized clusters (approximation of
an “outbreak”), and

apparent multiple cases in multiple locations (approximation
of an “epidemic”)
Response
This information is available for each report in
Evolve and thus represents granularity down to the
lowest geographic unit presented in a given report
and by disease event
Response

what level of government and non-governmental
organization became involved in response by
disease event
Local Public Community Reaction

There are two basic areas presented here:
 reaction
of the public
 reaction
of responders
Local Public Community Reaction

Reaction of the public

The term ‘panic’ is not indicative of true panic but rather a proxy for
social concern

‘Panic with behavior’ is where we have documented non-routine public
behavior such as panic buying, hoarding of medications, and so on, where
concern has elicited non-routine action

‘Flight’ is the ultimate outcome where a community’s inhabitants abandon their
community and for a period of time, social disintegration is observed. This is
the end point of infectious disease event damage from a sociological
perspective, where a community ceases (transiently) to be an integrated
social unit engaged in routine daily activities

Evacuation due to biological events is a rare phenomenon, but one for which
we maintain a baseline for what diseases in what countries provoke such a
reaction
Local Public Community Reaction

Reaction of responders
 Responder
anxiety, which follows the same conceptual
framework as public anxiety
 Here
it is key to note those events where healthcare
workers refuse to perform their duties or participate in
response due to fear of exposure, illness, or death
 Responder
avoidance of duties is a rare phenomenon
Infrastructure
This information is available for each report in
Evolve and thus represents granularity down to the
lowest geographic unit presented in a given report
and by disease event in SE Asia
Infrastructure

The infrastructure types affected (compromised) by
infectious disease events in SE Asia either due to
 absenteeism,
 contamination,
 work
overload (i.e., response), or
 any combination of the above
Infectious Disease Disaster
This information is available for each report in
Evolve and thus represents granularity down to the
lowest geographic unit presented in a given report
and by disease event in SE Asia
Infectious Disease Disaster

The most socially disruptive events in SE Asia, by
country and disease that are assessed to be
potential disasters
 0.6%
of all disease reports in SE Asia

Auto-generated (machine-learning) tags.
These tags are semantically ranked (a
statistical probability match). Users can further
train the classifier by accepting or rejecting a
suggestion. Users can similarly train the geolocator by simply accepting or rejecting and
updating a location.

 > 100 infectious diseases
 > 180 micro-organisms
 > 140 symptoms
 > 50 chemicals
