  • Oklahoma has changed to weekly reporting (Thursdays)

November 12, 2021

Oklahoma

  • Recent changes to Oklahoma's COVID-19 dashboard have resulted in a spike in the number of reported deaths and in the discontinuance of county-level reporting of fatalities. The tally for COVID-19 deaths on Oklahoma's website reflects only the statewide toll and is labeled as "CDC Provisional Deaths Mentioning COVID-19." We are investigating whether we would be able to back-distribute fatality information to more accurately reflect the state's situation. We will update this announcement if this process is successful. For now we will only be able to update the "Unassigned, Oklahoma" entry for Oklahoma in time_series_covid19_deaths_US.csv. Counties will be stale.

Oklahoma

  • On October 19, 2021, Oklahoma increased the cumulative deaths to better align with CDC reporting. This resulted in 1,138 deaths being reported on this date, though those deaths did not all occur on that date.

May 18, 2021

Oklahoma

  • Oklahoma’s testing trends are incomplete because the state has not reported any information between May 5-11. And since May 12 the state has reported positive tests without reporting the total number of new tests administered. That has made it impossible to calculate a test positivity rate over the past six days. We are awaiting answers from the state about the reporting process.

Oklahoma

  • Declines in U.S. cases and deaths that appear in the Coronavirus Resource Center’s data on Mondays are the result of several states not reporting the information over the weekend.

The daily number of COVID-19 cases and deaths in the United States also included this data.
