| Outline of Final Research Achievements |
The purpose of this research project is to present a novel perspective to the theoretical research with the mathematical modeling about the nature of biological population dynamics which consists of processes with different time scales. In today's society the time scale of the dynamics of information transmission on a disease spread is faster than that of the dynamics of disease transmission itself. With analyses on some fundamental mathematical models, we have obtained theoretical results to imply that the social response (a sort of collective behavior in human society) induced by such an information spread could be an important factor to cause a repetitive outbreaks of spreading disease.

| Academic Significance and Societal Importance of the Research Achievements |
本研究課題において実施した研究においては，ヒト集団における感染症の伝染ダイナミクスがヒト集団の集団行動に依存する特性をもつことに焦点を当て，新しい数理モデリング，数理モデルによる理論研究の課題を提示することができた。感染症の伝染ダイナミクスは，時間スケールの異なる過程が複合的に構成する典型的なダイナミクスであり，コロナ禍を経て，このような分野横断的な研究課題が重要な科学的意味をもつことも改めて認識されている。今後の感染症伝染ダイナミクスの理論的基礎研究の発展の一助となる研究成果が得られたと考えている。
