  1. Forensic Epidemiology in Law Enforcement and Public Health2004 California Medical and Health Disaster Management Conference Gregory Evans Institute for Bio-Security Saint Louis University School of Public Health

  2. Botulism • Mode of Exposure • Inhalational • Food-borne • Clinical Features • Muscle paralysis • Respiratory failure • Treatment • Botulinum antitoxin • Supportive care

  3. Consequence Management • Local and State Public Health Departments • Local Medical Care facilities • Support from Centers for Disease Control and Prevention

  4. Observations from National Exercises • Local sources of supplies • identify reserve medical personnel • Number and types of treatment beds available • Number and type of medical and security personnel • Have hard copies of all material you might need

  5. Observations from National Exercises • Types and amounts of medications needed • Algorithm for who will receive treatment • Source of nurses or respiratory therapists for ventilators • Determine auxiliary facilities for treating patients • Determine how hospital facilities can be maximized

  6. Observations from National Exercises • Do not assume area hospitals will be able to take overload • Need content experts for most common bioterrorist agents

  7. Differences Can Create Difficulties • Who’s in Charge? • Early Notification!

  8. New Partners, New Paradigms • Security Clearances • Chain of Custody • Confidentiality Issues

  9. Public Health and Law Enforcement Interviews • Much of the information both investigators need to obtain is the same • However, both investigators have unique perspectives/background/experience

  10. Law Enforcement: Stop further food poisonings Control the panicking public Collect information to apprehend and convict the terrorists Public Health: Stop further food poisonings Coordinate treatment of victims Collect epidemiologic information that might prevent future attacks Public Health and Law Enforcement Goals Compared

  11. Epidemiology • Originally, the study of epidemics • Outbreak is a more localized term for epidemic • Study of the factors that contribute to illness in individuals and communities, and how to reduce disease by altering those factors

  12. Public Health Emergencies • Bioterrorism have focused attention on public health preparedness for emergencies • In the case of botulism poisoning, public health has moved from secondary responder to one of the primary responders

  13. Local-State-Federal Relationships • Local health agencies • State health agencies • Federal agencies

  14. Public Health ‘Police Powers’ • Inspect or close premises • Limit the movements of people (isolation, quarantine) • Require vaccination, testing, or treatment

  15. Public Health ‘Police Powers’ • Seize, embargo, impound food and other hazardous substances, or stop their sale • Board planes, trains, buses, and ships as part of disease control • Review medical and hospital records • Interview whoever and whenever information is needed for investigation of a public health problem

  16. How Do Infectious Diseases Spread? • Common source • Person-to-person • Vector-borne • Airborne

  17. Steps in an Outbreak Investigation • Detect problem • Verify diagnosis • Confirm epidemic • Identify cases • Characterize data ® time / place / person • Take immediate control measures

  18. Signs of an Intentional Outbreak • Cases of an extremely rare disease • Ordinary disease but out of season or area or with wrong mode of spread or other unusual characteristics • Cannot solve outbreak with usual techniques • Threats received • Group taking credit • Plausible accusations

  19. Signs of an Intentional Outbreak • Victims attended a common event • Victims share a common workplace or other locale • A dissemination device is found • Victims live in same geographical area • Victims have recently traveled by common conveyance
