Understanding Avian Influenza: Modeling, Impact, and Prevention Strategies

This research, led by John Fujita at the Pacific Disaster Center under the supervision of Mike Napier from the University of Hawaii, focuses on avian influenza, a virus prevalent in birds and related to common flu. The study highlights the ecological cycle of the disease, its economic impact illustrated by past outbreaks, and the potential threat of a pandemic affecting millions globally. The project aims to develop a knowledge base through geospatial data and human case studies to inform prevention and mitigation strategies, ultimately advocating for increased funding to save lives.

Presentation Transcript

  1. Avian Influenza Modeling By: John Fujita Research Institution: Pacific Disaster Center Research Supervisor: Mike Napier Home Institution: University of Hawaii, Manoa

  2. Background on Avian Influenza • Family orthomyxoviradae • Relative of common flu • Most prevalent in birds • Spread • Direct contact • Fecal matter • nasal and ocular discharges • Symptoms • Pneumonia, eye infections, pancreatic damage, and severe respiratory diseases

  3. Economic Impact • 1983–1984outbreak of Highly Pathogenic AI in the USA • Destruction of more than 17 million birds • $63 million in Federal funds • additional $350 million in increased consumer costs

  4. Historic Pandemics • 1918-1919 Spanish Flu • Worst Pandemic in History • 50 Million Deaths • Over 500,000 dead in US • 1957-1958 Asian Flu • 70,000 deaths in US • 1968-1969 Hong Kong Flu • 34,000 deaths in US

  5. Potential Impact of a Pandemic • 20-50% of the world human population infected • 250 million deaths "We at WHO [the World Health Organization] believe that the world is now in the gravest possible danger of a pandemic…" Dr. Shigeru Omi, the WHO's Western Pacific Regional Director, 23 February 2005

  7. Recent Breakouts • 108 confirmed human case studies • Infection clusters • First-time infection of multiple species • Death rate going down

  8. My Contributions • Human case studies (at provincial level) • World Health Organization ~2004 • Animal case studies (at least district level) • OIE ~1997 • GIS data layers • Poultry and population density • Migratory bird flyways • Airline routes • Geospatial data • Rainfall, elevation, temperature, humidity, hydrology, wind direction

  9. Conclusion • MORE FUNDING for PDC • Saving of millions of lives

  10. Future of Project Develop knowledge base and gather raw data- John Fujita and Mike Napier Preliminary Model and Analysis – John Fujita and Mike Napier Develop contacts and obtain complete data – Allen Clark Complete Model and Analysis – Mike Napier Draw insightful conclusions- Mike Napier
