Battle with COVID-19 turned out to be a marathon, not a sprint, and behavioral adjustments have been unavoidable to stay viable. In this paper, we employ a data-centric approach to investigate individual mobility adaptations and mask-wearing in Seoul, South Korea. We first identify six epidemic phases and two waves based on COVID-19 case count and its geospatial dispersion. The phase-specific linear models reveal the strong, self-driven mobility reductions in the first escalation and peak with a common focus on public transit use and less-essential weekend/afternoon trips. However, comparable reduction was not present in the second wave, as the shifted focus from mobility to mask-wearing was evident. Although no lockdowns and gentle nudge to wear mask seemed counter-intuitive, simple and persistent communication on personal safety has been effective and sustainable to induce cooperative behavioral adaptations. Our phase-specific analyses and interpretation highlight the importance of targeted response consistent with the fluctuating epidemic risk.

跑 COVID-19 马拉松：在韩国首尔大流行 27 周内，行动能力和口罩的行为适应

事实证明，与 COVID-19 的战斗是一场马拉松，而不是短跑，为了保持活力，行为调整是不可避免的。在本文中，我们采用以数据为中心的方法来调查韩国首尔的个人移动适应性和口罩佩戴情况。我们首先根据 COVID-19 病例数及其地理空间分布确定了六个流行阶段和两个波次。阶段特定的线性模型揭示了在第一次升级和高峰期的强烈、自我驱动的流动性减少，共同关注公共交通的使用和不太重要的周末/下午旅行。然而，第二波并没有出现类似的减少，因为焦点从移动到戴口罩的转移是明显的。虽然没有封锁和轻推戴口罩似乎违反直觉，关于人身安全的简单而持久的交流对于诱导合作行为适应是有效且可持续的。我们针对特定阶段的分析和解释强调了与波动的流行病风险相一致的针对性反应的重要性。
