Well this is seriously sketchy, and feel free to correct me if my interpretation is incorrect, but the CDC has recently released a Lab Alert notifying healthcare providers they are withdrawing their emergency use request of the SARS-COV-2 rapid response diagnostic; and informing test centers to adopt new, modified, COVID testing that does not conflate influenza (the flu) with positive results for COVID-19. This looks like a back-door admission that many of the COVID positive results were actually, perhaps intentionally & purposefully, Flu cases diagnosed as COVID. If so, this would explain why the number of cases of influenza disappeared...
