The Oklahoma State Department of Health reported on Wednesday 3,249 new cases of COVID-19, bringing the state's total to 287,030.
Tulsa County had 411 of Wednesday's cases. Its total now stands at 47,575, second to Oklahoma County's 57,401.
The state's seven-day average of new cases, which shows the trend in infections, decreased slightly, from 2,594 to 2,536. The previous record of 3,535 was set on Christmas Day.
The holidays are suspected to be responsible for a drop-off in testing and artificially low case numbers in the state.
