Spatiotemporal Characteristics of COVID-19 Epidemic in the United States

Category: Article Summary

Topic: Transmission

• COVID-19 incidence significantly decreased in early April in counties in the northeastern US (estimated weekly percentage change: -16.6%), but continued increasing in the Midwest (+13.2%), South (+5.6%) and West Regions (+5.7%). There was a higher likelihood of clustering and higher incidence of COVID-19 in metropolitan compared to rural counties, counties closest to core airports, in the most populous counties, and in counties with the highest proportion of racial/ethnic minority populations. However, geographic differences in incidence have decreased since early April.
