我们研究了美国各县贫困水平的COVID-19感染和死亡的传播情况。在大流行开始时，贫困程度极低或极高的县报告的病例数最高。人口密度高的县普遍存在U型关系，而在人口密度低的县中，只有较贫困的县报告COVID-19的高发病率。其次，我们讨论了从高收入国家向低收入国家传播感染的模式。第三，我们表明，在经历了不利天气冲击的高收入县，呆在家里的任务造成了显着更高的流动性减少比县没有。这些影响在贫困率高的县不存在。利用天气冲击与居家强制措施相结合作为保持社交距离的工具，我们发现采取的促进社交距离的措施有助于抑制高收入县的感染，但对低收入县没有帮助。这些结果对未来遏制传染病的传播具有重要的政策意义。
We study the spread of COVID-19 infections and deaths by county poverty level in the US. In the beginning of the pandemic, counties with either very low poverty levels or very high poverty levels reported the highest numbers of cases. A U-shaped relationship prevails for counties with high population density while among counties with low population density, only poorer counties report high incidence rates of COVID-19. Second, we discuss the pattern of infections spreading from higher to lower income counties. Third, we show that stay-at-home mandates caused significantly higher reductions in mobility in high income counties that experienced adverse weather shocks than counties that did not. These effects are not present in counties with high poverty rates. Using weather shocks in combination with stay-at-home mandates as an instrument for social distancing, we find that measures taken to promote social distancing helped curb infections in high income counties but not in low income counties. These results have important policy implications for containing the spread of infectious diseases in the future.
