Outline of Final Research Achievements

Although disease burden of influenza in Asian developing countries is similar to that in developed countries, its epidemic characteristics (especially seasonality) is very different. In this study, we conducted epidemiological studies of influenza in two countries; the Philippines and Mongolia. In the Philippines, we calculated incidence rate by considering a fraction of health seeking and revealed that it could increase up to three times. In Mongolia, a field study was conducted in a suburb district of Ulaanbaatar, and it was revealed that the frequency of tachycardia is significantly higher in hospitalized children with influenza compared with respiratory rates and SpO2 measurement. In addition, we found that the highest number of outpatient children with influenza was 1-4 years old than that in school children.

Academic Significance and Societal Importance of the Research Achievements

本研究ではアジアにおける2つの国におけるフィールド調査によりインフルエンザの疾病負荷と季節席を明らかにしたところに意義があると考えられる。最初に設定した学童での流行動態によってインフルエンザの流行と季節性については明確な関連性を示し得なかった。更なる解析を実施する予定であるが、感染拡大を誘因する別な要因についても検討が必要であると考えられる。
