The state health department reported 585 new cases on Wednesday. Thursday's numbers have more than doubled with 1,620 new cases of COVID-19.
"To really know if we might be seeing an increase, it takes a few days," state epidemiologist Jolianne Stone said. "Almost even a week, to see if we are truly seeing an increase or are we really seeing a plateau.”
There are currently 515 Oklahomans in the hospital with COVID-19. Out of the 515 hospitalizations, 158 are in intensive care units.
On Wednesday, there were 482 Oklahomans in the hospital with 151 of those in the ICU.
"Hospitalizations are what we call a lagging indicator," Stone said. "So, in the middle of November, we started to see an increase a little bit in cases and now they have plateaued. And this might be in response to the increase in cases we have seen over the month."
State health officials are urging Oklahomans to get vaccinated or boosted if they are eligible.
"Supply wise we are fantastic," said Buffy Heater, the Assistant Deputy Commissioner of Personal Health Services. "There are hundreds of thousands of doses of Pfizer and Moderna that are across the state in freezers."
If you got an mRNA vaccine, Pfizer of Moderna, you can get a booster six months after your second dose. If you received Johnson and Johnson's vaccine, you only must wait two months after getting the dose.
