Mission
To develop a global center of excellence in Hawaii for emerging and re-emerging infectious diseases
Emphasis will be placed on infectious diseases of the Asia-Pacific Region, and on developing trans-disciplinary research and development programs that will result in new diagnostics, drugs, vaccines and other treatment and prevention modalities.
Asia-Pacific Institute of Tropical Medicine and Infectious Diseases
ASIA-PACIFIC INSTITUTE OF TROPICAL MEDICINE AND INFECTIOUS DISEASES
• Develop a balanced trans-disciplinary research and training program that focuses on basic, field and translational research.
• Develop a laboratory reference and research center
• Develop local and international partnerships.
• To build laboratory and epidemiologic capacity, and research collaborations in selected countries of Asia where diseases with epidemic potential commonly occur.
• Develop a graduate program that will attract highly motivated, research-oriented doctoral candidates.

Factors Responsible for Increased Epidemic Infectious Diseases
• Complacency, Lack of Political Will• Policy Changes• Changes in Public Health • Demographic Changes
- Population growth- Urbanization- Agricultural/Land Use Practices- Animal Husbandry
• Modern Transportation- Increased Movement of People, Animals, Commodities
• Changing Life Styles/Behavior• Microbial Adaptation• Technology• Intent to Harm• Climate Change?
Zoonotic Diseases: Hitching a Ride? Modern Transportation
Asia-Pacific Institute of Tropical Medicine and Infectious Diseases
Hawaii and the US mainland are highly vulnerable to the importation of exotic pathogens, and at high risk for epidemic disease.
Demographic and cultural factors, along with economic growth and globalization will insure that the Asian region will be important in
producing future epidemic disease.
A center of excellence for research on emerging infectious diseases of Asia and the Pacific in Hawaii will be highly beneficial to the global
efforts to detect, respond and control epidemic disease.
