The state's seven-day average of new cases, which shows the trend in infections, jumped from 3,002 to 3,172, its second straight new record and sixth in the past seven days. Oct. 5 was the last time the seven-day average was below 1,000.
Tulsa County's seven-day average of new cases rose from 428 to a new high of 455. Its the third new high in the past five days. The previous high was 441, set on Saturday.
The state reported 15 deaths, with none in the past 24 hours. A Tulsa County woman 65 or older was reported dead. Statewide, a Cleveland County man 36 to 49 years old, three adults 50 to 64 years old and 10 adults 65 or older were also reported dead.

There were 1,566 Oklahomans hospitalized for COVID-19 on Monday evening, 61 more than on Friday and a second straight new record. Of those hospitalized Monday, 1,500 had positive coronavirus tests. Overall, 446 Oklahomans hospitalized for COVID-19 were in intensive care units, four fewer than Friday's record number.
According to the state health department, Tulsa County had 335 residents hospitalized as of Monday evening, 15 fewer than on Friday. The record of 351 was set last week.
Over the course of the pandemic, 11,445 Oklahomans have been hospitalized for COVID-19.
As of Monday, the state reported 5% of its adult ICU beds and 15% of its medical surgery beds were available. Five of Oklahoma's eight hospital regions, including Oklahoma County, are at tier three of a four-tier hospital surge plan, meaning 20% to 40% of patients have tested positive for COVID-19 for at least three consecutive days. Tulsa County is at tier two, with 15% to 20% of patients testing positive. Only the east central region remains in tier one.
The state health department reported 3,305 additional patients as recovered on Tuesday, bringing the total to 145,686. 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 33,260 active cases of COVID-19, 584 fewer than the day before and the first decline in seven days.
Tulsa County reported 486 additional patients as recovered, bringing the total to 25,651. The county has 5,008 active cases, 70 fewer than the day before and the first decline in a week.
The state's reported overall positive test rate rose 0.1 percentage points Monday to 9.3%. Out of 48,353 tests reported on Monday, 16% were positive. Each positive test does not necessarily represent a unique individual.
The state also reports 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 Monday, that rate was 8.9%, up 0.4 percentage points from Friday.
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.
