We’re still in week 51 of this flu season which will include at least two months in 2021. We’re at a record low but the virus isn’t “almost nonexistent”
It is also likely that they’re seeing far more Covid cases than influenza cases since the former is more contagious and fatal than the latter.
People who are sneezing and with fever are staying home.
People who are having trouble breathing are going to the hospital.
The cases are thus reported as a record low for one and record high for the other.
