So, you are saying that all of the virus panel tests I see daily are fake?
NN, what you see is a tiny part of what’s going on nationwide.
Or, in this case, what’s not going on nationwide.
Personally I believe the flu was knocked off by these preventive measures, but what someone else would argue is that your sample is not random nor representative of the world.
I imagine somebody has collected samples such as yours from widespread areas, which would help counter that argument. They’ve probably even published papers about it.
