"CDC encourages laboratories to consider adoption of a multiplexed method that can facilitate detection and differentiation of SARS-CoV-2 and influenza viruses"
That's a long way of saying "PCR tests can't tell them apart".
No it isn’t. Not at all. A pcr that is looking for sequences common in coronavirus but not influenza is not likely to confuse the two.
A multiplexed method is going to look for flu like symptoms, lung xrays, — ie less definitive methods of diagnosis for a particular virus. Thats why they are talking about differentiation. Its harder to differentiate between viruses when you take away the test.
