There was something else going around. lots of people had it. It was too early and too widespread to have been CCP-19 if the timeline we know about is accurate. I don’t dispute it was nasty - I had what ever it was, too. But I think it had to have been a flu strain or a vicious cold.
Widespread testing will tell us. Coming soon.
I remember seeing stories here of people who got whatever it was twice...so they need to be tested with the new test coming out to see if they had it..if they dont mind being put in a database
