COLUMBUS, Ohio (WCMH) — Ohio, along with the rest of the United States, has entered a new phase in the latest wave of COVID-19, driven by the delta variant of the virus.

Last week the state saw its most cases since September, and the newly discovered omicron variant lofts uncertainty on top of increasing infections. Cases are rising in every county in the Buckeye State, but they’re not rising evenly everywhere.


The Ohio Department of Health often references the rate of onset cases per population over the past two weeks as it keeps track of the virus’ spread. Ohio’s rate of onset cases per 1,000 residents in the past two weeks is 6.64 as of Sunday, Dec. 5.

Leading the state are these 10 counties, mostly smaller in population and located in the northern half of the state:

10. Van Wert County: 9.05 cases per 1,000

9. Marion County: 9.11 cases per 1,000

8. Fulton County: 9.40 cases per 1,000

7. Lake County: 9.44 cases per 1,000
