After adding over 503,000 new cases throughout the last week, the U.S. now has more than 45.1 million confirmed cases of COVID-19. There have been more than 730,000 COVID-19-related deaths — the highest death toll of any country.

New cases continue to rise, albeit at a slowing rate. In the past week, there were an average of 22.8 daily new coronavirus cases per 100,000 Americans — a decrease from the week prior, when there were an average of 28.7 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 neighborhoods and a large population may be particularly at-risk.

The Charleston, WV, metro area consists of Kanawha County, Jackson County, Boone County, and two other counties. In the past week, there were an average of 55.3 new coronavirus cases every day per 100,000 Charleston 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 was an average of 66.6 daily new cases per 100,000 Charleston residents.

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

Case growth in the Charleston metro area varies at the county level. In Kanawha County, for example, there were an average of 51.7 new cases per day per 100,000 residents in the past week — the least of any county in Charleston and more than the case growth rate in Clay County.

While Clay County is driving the growth of COVID-19 in the Charleston area, it does not have the highest incidence of cases overall. As of October 26, there were a total of 13,985.5 confirmed cases per 100,000 residents in Clay County, the second most of the five counties in the metro area. For comparison, the U.S. has so far reported 13,906.4 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 Clay County, unemployment peaked at 19.1% in April 2020. As of June 2021, the county’s unemployment rate was 7.7%.

To determine the county in every metropolitan area where COVID-19 is growing the fastest, 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 October 26. To estimate the incidence of COVID-19 at the metropolitan level, we aggregated data up 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 West Virginia where COVID-19 is slowing (and where it’s still getting worse).
