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.

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.
