当前COVID-19的爆发对相互关联的人类社会构成了前所未有的全球健康和经济威胁。控制疫情的策略依赖于社交距离和面部覆盖措施，这些措施在很大程度上切断了城市的社交网络结构。我们证明，在美国疫情爆发的早期，COVID-19在大城市的平均传播速度更快，并讨论了这些观察结果的影响，强调了在大城市更快应对新型传染病的必要性。
The current outbreak of COVID-19 poses an unprecedented global health and economic threat to interconnected human societies. Strategies for controlling the outbreak rely on social distancing and face covering measures which largely disconnect the social network fabric of cities. We demonstrate that early in the US outbreak, COVID-19 spread faster on average in larger cities and discuss the implications of these observations, emphasizing the need for faster responses to novel infectious diseases in larger cities.
