  2. SE Asia Early Warning & Response A collaborative early warning and response space for latest health-related events in SE Asia

  3. 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%)

  4. 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

  5. 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

  6. 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”)

  7. 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

  8. Response • what level of government and non-governmental organization became involved in response by disease event

  9. Local Public Community Reaction • There are two basic areas presented here: • reaction of the public • reaction of responders

  10. 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

  11. 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

  12. 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

  13. 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

  14. 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

  15. 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

  16. InSTEDD Evolve RSS Publishing Save filter (by keyword, tag, topic, location, and time) and email subscription Delete/Recycle an Item Expert-generated Tags Related items (e.g., News articles) are grouped into a thread. Threads are later associated with events (hypothesized or confirmed). Tag cloud and semantic heat map Delete/Recycle an Item InSTEDD Evolve: (http://instedd.org/evolve)

  17. InSTEDD Evolve InSTEDD Evolve: (http://instedd.org/evolve) Our Solution

  18. InSTEDD Evolve Filter feature which automatically filters content by topic of interest Filter feature which automatically filters content by radius InSTEDD Evolve: (http://instedd.org/evolve)

  19. InSTEDD Evolve 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 geo-locator by simply accepting or rejecting and updating a location. InSTEDD Evolve: (http://instedd.org/evolve)

  20. Automatic Classification • Current classification includes: • 7 syndromes • 10 transmission modes • > 100 infectious diseases • > 180 micro-organisms • > 140 symptoms • > 50 chemicals

  21. Information Sources • BBC Outbreak News • BioCaster Open Source Ontology • CNN Health News • EpiSpider • Eurosurveillance • Google Outbreak News • HealthMap (Global Disease Alert Map) • HEDDS Surveillance News • Moreover Public Health News • ProMed News (including MBDS) • Veratect Corporation • WDIN Disease Map Digest • WHO Latest news on the avian influenza situation in humans around the world • WHO Outbreak News • Y! Health Cold & Flu News

  22. InSTEDD Evolve Tracking the recent Avian Influenza Outbreak in Egypt (reports started to appear late January 2009). Notice the pattern of reported incidents along the Nile river. InSTEDD Evolve: (http://instedd.org/evolve)
