The "Go To Travel" campaign in Japan, which encouraged people to travel throughout the country, was implemented in July 2020 to revitalize economic activity that was sluggish due to COVID-19. Although the risk of the spread of infection has been reported for tourists crossing prefectural borders, the spread of infection among residents living in tourist areas is unclear. The present study evaluated the number of COVID-19 cases among residents of tourist resort areas in Gunma Prefecture using a descriptive epidemiological method. Data regarding infected individuals were obtained from public data available on the prefecture's official homepage. Evaluation of epidemic curves showed that the number of cases increased slightly after the start of the campaign, with numbers affected by the occurrence of clusters. Toward the end of 2020, the number of cases increased in both resort and non-resort areas, although the increase was smaller in resort areas. Thus, the increased transmission of cases during the campaign suggested a need to take additional preventive measures, more-so for tourists than for resort area residents.
日本于 2020 年 7 月推出了“去旅行”活动，鼓励人们在国内旅行，以振兴因 COVID-19 而萎靡不振的经济活动。虽然有报道称游客跨越县界旅行存在感染风险，但居住在旅游区的居民的感染传播情况尚不清楚。本研究采用描述性流行病学方法评估了群马县旅游度假区居民的 COVID-19 病例数。感染者数据从县官方主页上提供的公共数据中获得。对流行曲线的评估表明，该活动开始后病例数略有增加，受集群发生的影响。2020 年底，度假胜地和非度假胜地的病例数都有所增加，尽管度假胜地的增幅较小。因此，活动期间病例传播增加表明需要采取额外的预防措施，对于游客而言比度假地区居民更为重要。
