キーワード:COVID-19、 airport users、 hotel visitors、 mobility、 effective reproduction number、 Go To Travel Campaign
Background: Long distance travel for sightseeing was believed to spread outbreak and had been banned until 2022. However, it had never been examined in detail.
Object: Object of this study was to confirm effect of long distance travel to infectivity in a resort island including the period when the mutated strain dominated.
Method: We used unique data about daily number of Yakushima airport users and visitors in a major hotel in Yakushima so as to evaluate how long distance travelers affect infectivity. Study period was since January 1, 2022 to August 10m 2022 when omicron variant strain dominated.
Results: Long distance travels, airport users and hotel visitors, were not significant at all.
Discussion and Conclusion: Estimation results about number of long distance travelers might not affect infectivity.
