Development of an infectious disease dynamic model incorporating location heterogeneity of outbreaks
To deeply understand the dynamics of infectious disease outbreaks, it is essential to construct models considering heterogeneities such as age, geographic location, and immune status. The COVID-19 pandemic has reaffirmed the importance of incorporating such heterogeneities into models. In the early stages of the pandemic, Japan focused its countermeasures on clusters, targeting locations where group infections occurred. However, the extent to which this heterogeneity of infection sites influences disease transmission remains ambiguous. This research aims to integrate the heterogeneity of infection sites into models and evaluate its impact. Furthermore, the study will scrutinize the transmission mechanisms distinguishing COVID-19 from influenza, quantitatively elucidating the significance of including data on infection sites in future surveillance efforts for infectious diseases.


The interdisciplinary network formed through the Inamori Research Grant will serve as a powerful tool in tackling increasingly complex social issues. From the perspective of infectious diseases mathematical models, I will dedicate myself to contributing to the advancement of science.
