Hours before the news broke, UPMC Medical Director of Infection Prevention and Epidemiology Dr. Graham Synder said he wouldn’t have been surprised if Omicron was already in Pennsylvania, though Delta is still the dominant strain. Snyder says UPMC has a lab that can sequence and identify a specific type of virus.

“We are in the process of trying to start tracking, so we are going to start looking at the tests that are coming in,” Dr. Brian Lamb, a primary care internist at AHN, said. “We’ve done this before with Delta where we take batches of tests and run it through and see what variant it is.”
