Figure 7
Simulated numbers of infectious people by prefecture under the assumptions that the government either does or does not restrict the interregional mobility of infectious people to remain in their residential prefectures. Shown are the observed numbers of infectious people up to April 25, 2021 (blue lines), the numbers of infectious people simulated by the spatial SEIR model without interregional mobility (green lines), and those simulated by the spatial SEIR model with interregional mobility, assuming that the interregional mobility of only infectious people is restricted (purple lines) or that free mobility across prefectures is allowed for all individuals (red lines). The simulations were started on April 25, 2021.
