After adding over 934,000 new cases throughout the last week, the U.S. now has more than 42.1 million confirmed cases of COVID-19. There have been more than 670,000 COVID-19-related deaths — the highest death toll of any country.

New cases continue to rise at a steady rate. In the past week, there were an average of 45.1 daily new coronavirus cases per 100,000 Americans — essentially unchanged from the week prior, when there were an average of 49.5 daily new coronavirus cases per 100,000 people.

While COVID-19 has spread to nearly every part of the country, cities continue to be the sites of major outbreaks. 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.

The Knoxville, TN, metro area consists of Knox County, Blount County, Anderson County, and five other counties. In the past week, there were an average of 109.6 new coronavirus cases every day per 100,000 Knoxville residents, greater than the national figure. The metro area’s average daily case growth in the most recent week is a decrease from the week prior, when there were an average of 128.1 daily new cases per 100,000 Knoxville residents.

The spread of coronavirus depends on a variety of factors and can vary even between neighboring counties. Within the Knoxville metro area, COVID-19 is growing the slowest in Anderson County. There were an average of 94.0 new cases per day per 100,000 residents in Anderson County during the past week, the least of the eight counties in Knoxville with available data.

Case growth in the Knoxville metro area varies at the county level. In Campbell County, for example, there were an average of 146.3 new cases per day per 100,000 residents in the past week — the most of any county in Knoxville and more than the case growth rate in Anderson County.

While Anderson County has the slowest case growth in the Knoxville area, it does not have the lowest incidence of cases overall. As of September 23, there were a total of 15,565.1 confirmed cases per 100,000 residents in Anderson County, the third fewest of the eight counties in the metro area. For comparison, the U.S. has so far reported 12,985.5 cases per 100,000 Americans nationwide.

In order to slow the spread of COVID-19, city and county governments have ordered the closure of thousands of consumer-facing businesses. These measures have led to widespread job loss and record unemployment. In Anderson County, unemployment peaked at 14.9% in April 2020. As of June 2021, the county’s unemployment rate was 5.4%.

To determine the county in every metropolitan area where COVID-19 is growing the slowest, 24/7 Wall St. compiled and reviewed data from state and local health departments. We ranked counties according to the average number of new daily COVID-19 cases per 100,000 residents in the seven days ending September 23. To estimate the incidence of COVID-19 at the metropolitan level, we aggregated data from the county level using boundary definitions from the U.S. Census Bureau. Population data used to adjust case and death totals came from the U.S. Census Bureau’s 2019 American Community Survey and are five-year estimates. Unemployment data is from the Bureau of Labor Statistics and is not seasonally adjusted.

These are all the counties in Tennessee where COVID-19 is slowing (and where it’s still getting worse).
