As of Thursday, the state reported 5% of its adult ICU beds and 11% of its medical surgery beds were available. Also as of Thursday, seven of Oklahoma's eight hospital regions 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. The northwest region is currently at tier two. The OKC region has hovered near 35% the past few days. The Tulsa region dropped to 20% on Thursday.
The state health department reported 3,343 additional patients as recovered on Friday, bringing the total to 330,478. 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 32,327 active cases of COVID-19, 444 fewer than the day before. The record is 43,163, set Jan. 11.

The state's reported overall positive test rate was 11.4% on Thursday, unchanged from Wednesday. Out of 23,128 tests reported on Thursday, 11.2% were positive. Each positive test does not necessarily represent a unique individual.
The state used to report 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 Thursday, that rate was 12%, unchanged from Wednesday.
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.
There are 76 counties at the orange level on the state's COVID alert map, indicating the highest risk of transmission. Since last week, Cimarron County dropped from orange to green.
Tulsa County's rate of new cases per 100,000 population fell 23.2% this week, going from 95.6 to 73.4. The highest rate of new cases was in Alfalfa County, which had a new case rate of 120.3, up 41.2% from last week.
The orange level starts at 14.3 new cases per 100,000. There are five counties with new case rates over 100.
Regardless of transmission rates, counties are not classified at red, the alert map's highest level, unless COVID patients account for 40% of the staffed hospital beds in that county's state hospital region.
