The Oklahoma State Department of Health reported on Monday 869 new cases of COVID-19, bringing the state's total to 70,223.
It was the highest number of new cases on a Monday since 1,401 were reported July 27. The state has since started including positive antigen tests in its case totals.
Tulsa County had 56 of the cases reported Monday. Its total stands at 15,202, second to Oklahoma County's 15,293.
The state health department did not report any deaths. Oklahoma surpassed 900 known coronavirus deaths over the weekend, when six deaths reported Sunday brought the total to 905.
The state's seven-day average of new cases, which shows the trend in infections, rose from 821 to 858, its highest point since Aug. 2. The state's average peaked at 1,093 on Aug. 1 and had fallen to 645 by late August.
Tulsa County's seven-day average dropped from 138 to 133. It peaked at 254 on July 30, then fell to 117 on Sept. 1, its lowest point in nearly two months, before climbing back to almost 160 last week.
There were 499 Oklahomans hospitalized for COVID-19 on Friday, 10 fewer than on Thursday. It was just the third time since July 10 fewer than 500 Oklahomans were in the hospital with the illness. Of those hospitalized Friday, 438 had positive coronavirus tests. Overall, 186 Oklahomans hospitalized for COVID-19 were in intensive care units, 22 fewer than on Thursday.
The Tulsa Health Department reported 234 residents hospitalized as of Friday, matching a high set Wednesday. Local hospitalization numbers change frequently based on new data. Tulsa County hospitalizations have been trending up overall since the first week of June.
Over the course of the pandemic, 5,466 Oklahomans have been hospitalized for COVID-19.
As of Sunday, the state reported 21% of its adult ICU beds were available.
The state health department reported an additional 447 patients as recovered on Monday, bringing the total to 59,007. Patients are considered to have recovered if they did not die, are not currently hospitalized and it has been at least 14 days since their symptoms began. Symptoms have been reported to linger for several weeks for some individuals.
The state has 10,311 active cases of COVID-19, 422 more than the day before.
Tulsa County reported an additional 77 patients as recovered on Monday, bringing the total to 13,419. The county has 1,639 active cases, 21 fewer than the day before.
The state's reported overall positive test rate rose 0.1 percentage points Friday to 8%. Out of 13,590 tests reported on Friday, 10.6% were positive. Each positive test does not necessarily represent a unique individual.
The state has also started reporting its cumulative positive test rate, a metric used by Johns Hopkins Coronavirus Resource Center. It is calculated by dividing the number of cases by the number of negative tests plus the number of cases. As of Friday, that rate was 7%.
Johns Hopkins uses the different rate to compare states that may track testing differently. It notes the ideal way to calculate the positivity rate is dividing the number of people who test positive by the number of people who are tested, which is how Oklahoma's overall rate is calculated.
The World Health Organization's benchmark indicating adequate testing is a 5% positive test rate.
