Dynamic evolution map of L-DNM scores in Tokyo. Maps respectively in the 15th week (the normal stage), the 20th week (the pre-outbreak stage), the 25th week (the pre-outbreak stage) and the 30th week (the outbreak stage), are colored by the scaled value of L-DNM score (left of each submap) and the number of real clinic visits (right of each submap). It can be seen that the maps have no significant changes during the normal stage (e.g., the 15th week). However, as the system approaches the pre-outbreak stage (e.g., the 20th–25th week), the maps change dramatically, reflecting the apparent early warning signals of the upcoming outbreak
