OKLAHOMA CITY (AP) — Genome sequencing will be up and running this week at the state health lab to help identify variants of the COVID-19 virus, Oklahoma health officials said Thursday.

Officials with the Oklahoma Pandemic Center for Innovation and Excellence said two variants already were discovered earlier this month in Oklahoma. Those include the P.1 variant, known as the Brazilian variant, and the B.1 1.7 variant referred to as the U.K. variant. State health officials say it's likely additional strains are circulating in Oklahoma that have yet to be identified.

Meanwhile, Oklahoma reported 1,146 confirmed new coronavirus cases on Thursday and 38 additional deaths. That brings the total number of confirmed infections to 422,156 and the state’s death toll to 4,302.

The Oklahoma State Department of Health also reported Thursday that more than 935,000 vaccine doses had been administered so far in Oklahoma, including more than 285,000 Oklahomans who have received both doses. About 53% of Oklahomans aged 65 and older have received at least one dose, the OSDH reported.
