Inter-Prefectural Travel and Network Connectedness During the COVID-19 Pandemic in Japan.

ABSTRACT: BackgroundIncreases in human mobility have been linked to rises in COVID-19 transmission. The pandemic era in Japan has been characterized by changes in inter-prefectural mobility across state of emergency declarations (SOE) and travel campaigns, but they have yet to be characterized.MethodsUsing Yahoo Japan mobility data extracted from the smartphones of more than 10 million Japanese residents, we calculated the monthly number of inter-prefectural travel instances, stratified by residential prefecture and destination prefecture. We then used this adjacency matrix to calculate two network connectedness metrics, closeness centrality and effective distance, that reliably predict disease transmission.ResultsInter-prefectural mobility and network connectedness decreased most considerably durin
