“It could be that the flu season came early this year and is thus ending early.”
Wouldn’t that be nice! Different states are in different areas of the case curve though, it’s all very odd. (I haven’t done a good analysis of that, just poked around some). We’ve never followed the typical flu the way we follow CV19 with daily stats so I don’t have anything to compare the case rise and fall behavior of this virus.
A lot of the case surges were caused by testing, perhaps I should pay attention to testing rates perhaps being down per capita, those numbers are available in some states.
I don’t think it is that unusual for the flu to hit some states before others.
I wonder if flu can be correlated to how sunny or not it is in some states in winter.
There are winters where it has been gray for a month, though maybe not stormy, and other winters where it may have been colder on average temp-wise, but didn’t seem as bad because it was fairly sunny.
One January I had a heck of time on some of my work outings because so many trucks had crashed and tied up traffic due to tremendous sun glare problems.
