As of Sunday, the state reported 5% of its adult ICU beds and 16% 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.
The state health department reported 2,069 additional patients as recovered on Monday, bringing the total to 142,381. 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 33,844 active cases of COVID-19, 1,460 more than the day before. It's a new record for the sixth straight day.
Tulsa County reported 353 additional patients as recovered, bringing the total to 25,165. The county has 5,078 active cases, 153 more than the day before and a new record for the sixth straight day. It's the first time Tulsa County has had more than 5,000 active cases.
The state's reported overall positive test rate rose 0.2 percentage points Friday to 9.2%. Out of 57,400 tests reported on Friday, 12.9% 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 Friday, that rate was 8.5%, down 0.1 percentage points from Thursday.
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.
