I thought there are very few test sites to ID variants.
Meanwhile FOX is showing data showing 75% new cases are “O”, and how some states have as much as 90%, etc. where do they get this verification?
3 and a half weeks later, it's zer-mi-gob and er-my-god every second of every day...
They just make up the numbers to support the narrative.
Some of the PCR tests used by hospitals can infer omicron variant. The Thermo fisher test (article below) is looking at multiple genetic sites at least one of which is missing from omicron. So Delta will test positive for all sequence and I believe omicron is missing one sequence secondary to mutation.

So it's possible to discern this information depending on the hospital and the test equipment. Now whether Fox is getting the information from such a hospital or the hospital is inferring Omicron based on clinical presentation is anyone's guess
