After adding over 141,000 new cases on Jan. 24, the U.S. now has more than 24,600,000 confirmed cases of COVID-19. There have been more than 400,000 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 57.5 daily new coronavirus cases per 100,000 Americans — a decrease from the week prior, when there were an average of 71.9 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.

In the 50 largest metro areas, the incidence of coronavirus grew at an average rate of 61.2 new cases a day per 100,000 residents in the past week — 8.4% greater than the case growth in all counties outside of metro areas.

The Topeka, KS, metro area consists of Shawnee County, Jefferson County, Osage County, and two other counties. In the past week, there were an average of 52.1 new coronavirus cases every day per 100,000 Topeka residents, less 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 80.3 daily new cases per 100,000 Topeka residents.

The spread of coronavirus depends on a variety of factors and can vary even between neighboring counties. Within the Topeka metro area, COVID-19 is growing the fastest in Wabaunsee County. There were an average of 72.6 new cases per day per 100,000 residents in Wabaunsee County during the past week, the most of the five counties in Topeka with available data.

Case growth in the Topeka metro area varies widely at the county level. In Jackson County, for example, there were an average of 35.1 new cases per day per 100,000 residents in the past week — the least of any county in Topeka and far less than the case growth rate in Wabaunsee County.

While Wabaunsee County is driving the growth of COVID-19 in the Topeka area, it does not have the highest incidence of cases overall. As of Jan. 24, there were a total of 7,578.4 confirmed cases per 100,000 residents in Wabaunsee County, the third most of the five counties in the metro area. For comparison, the U.S. has so far reported 7,645.6 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 Wabaunsee County, unemployment peaked at 7.6% in April 2020. As of November 2020, the county’s unemployment rate was 4.3%.

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 Jan. 24. 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 2018 American Community Survey and are five-year estimates. Unemployment data is from the Bureau of Labor Statistics and is not seasonally adjusted.

County	Population	New daily cases per 100,000, week ending Jan. 24	New daily cases per 100,000, week ending Jan. 17	Cumulative cases per 100,000	Cumulative deaths per 100,000
Wabaunsee County	6,888	72.6	112.9	7,578.4	N/A
Shawnee County	178,284	54.8	80.5	7,780.3	N/A
Jefferson County	18,888	43.5	83.1	7,004.4	N/A
Osage County	15,882	37.1	66.6	6,082.4	N/A
Jackson County	13,318	35.1	72.6	7,981.7	N/A

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