Objective: A risk of dengue virus (DEV) infection is increasing in accordance with the increasing number of Japanese travelers to south-east Asia. In this study, we investigated dengue virus infection rate and risk factor of infection in East Timor. Study design and Methods: The subject of our research was Japanese Ground Self Defense Force (JGSDF) 608 troops who were dispatched to East Timor for Peace Keeping Operation (PKO) from March to September, 2002 and consented to participate this study. Questionnaire items were sex, age, rank, the type of job, blood type, residence, working and environmental factors, symptoms and so on. Peripheral blood samples drawn from subjects during or after dispatch were screened for IgM capture ELISA antibodies. A retrospective cohort study was conducted. Results: The number of case was defined as a positive case of dengue virus IgM antibody. Case was 8 (1.3%) of 608 troops and inapparent infection rate was 100%. There was no risk factor of DEV infection in Questionnaire items. Conclusion: We could obtain a basic information about dengue virus infection among Japanese adults staying in dengue endemic areas.
