This causal loop modelling suggested that the only effective measure against COVID-19 transmission in the Japanese context was intervention in the early stages of the outbreak by national and regional governments, and no social self-strengthening dynamics were demonstrated. In handling the complex COVID-19 transmission processes in the population and the effects of societal factors, the idea to use system dynamics, describing complex social systems as a collective set of mathematical equations, was drawn based on some considerations. As social components, intervention by national or local government [3] , awareness raising regarding physical distancing and hygiene measures [15] , countermeasures by private or public enterprises [16] , new business practices, working from home, and contact reduction in commuting were included.	./cache/cord-262647-kkvekors.txt	./txt/cord-262647-kkvekors.txt
