Did they ever find a way to differentiate between influenza and covid-19. Did they ever actually isolate covid? I lost track somewhere around 2020. Last I heard PCR does not distinguish between illnesses so I’m still wondering how they can detect it. I guess the antibody test lets them know…….. right? I’m also guessing that if I learn about the antibody testing it will become apparent that the anti-body test does not differentiate between flu strains or covid either.
