New cases continue to rise at a steady rate. In the past week, there were an average of 22.7 daily new coronavirus cases per 100,000 Americans — essentially unchanged from the week prior, when there were an average of 18.2 daily new coronavirus cases per 100,000 people.
While new data shows that the risk of contracting COVID-19 is high in almost every part of the country, cities continue to be the sites of major outbreaks and superspreader events. Experts agree that the virus is more likely to spread in group settings where large numbers of people routinely have close contact with one another, such as colleges, nursing homes, bars, and restaurants. Metropolitan areas with a high degree of connectivity between different neighborhoods and a large population may be particularly at-risk.
In the 50 largest metro areas, the incidence of COVID-19 grew at an average rate of 26.4 new cases a day per 100,000 residents in the past week — 23.3% greater than the case growth in all counties outside of metro areas.
