  6. Disasters Fatalism vs. Preparedness

  7. Risk Perception Our response to a real or imagined hazard is a function of our perception of that hazard. In many situations, hazards are ignored or disregarded. In other situations, they are magnified. Some of the factors which govern risk perception include: familiarity, degree of dread, memorability

  8. Applications of Epidemiology (A) Understanding the causes of a disaster (B) Understanding ways of controlling a disaster situation

  9. Data Sources • GlobalAviation Safety Network • U.S. Fed. Aviation Administration Air Transport Association National Transportation Safety Board

  10. 2001 Statistics • 34 fatal airliner accidents • 80% passenger carrying • 15% cargo carrying • 1118 fatalities among airplane occupants Aviation Safety Network

  19. Health and Airline Travel

  20. Potential Health Risks • From Acute Exposures • Deep Vein Thrombosis • Infection • Injury • Adverse events in the medically vulnerable

  21. Potential Health Risks • From Chronic Exposures • cancers/leukemia from • cosmic radiation • cabin air exposures

  22. The Great Hanshin Earthquake Tokyo Subway Sarin Attack Life Lines damaged normal Hospital Facilities damaged normal Phone Lines damaged normal Disaster information for hospitals not enough not enough Information Dispatched from the hospitals not enough not enough Patients concentrated to some hospitals yes yes

  23. Conclusions The information reviewed suggests that: • Air travel is one of the safest forms of transportation and accident risk is lower now than in previous years • there are about 22 hijackings per year; and, on average, 100 deaths from all forms of terrorism worldwide per year.
