I think I know what you are getting at: is the flu reporting is just getting shifted from flu over to COVID19 reporting.
IOW: they are both the same thing(s).
What they'll say, and what might true to a sense, flu cases have falling off due to the lockdowns/social distancing.
The mitigations put in place for C19 would have the same effect on the regular flu.
Maybe moreso because we have some immunity and vaccines for the flu.
So add social distancing, not being allow to work, and/or don't go to school and flu cases will plummet off the bottom of the chart.
Flu season is essentially over early this year .... "lockdown for the win !". That's what they will say.
On one hand, you'd think people would be more apt to go to the doctor if they came down with symptoms for the flu, because it could be Certain-Death-19 also.
But on the other, there is no way I'm going to the doctor or a hospital if I lived in an area with an outbreak like NYC or Jersey....for anything trivial
You'll just get sick.
