The only thing I know is I had the Wuhan symptoms in early Jan 2020. The problem is that the normal antibodies would have faded by now. There are other more sensitive tests but I can't get one of those. The other problem is Jan 2020 was "too early" to get it. So I am assuming I didn't have it unless it was that early flu/cold or later with no symptoms.
his whole covid 'endemic' is bogus
The 511,000 increase in deaths in 2020 over 2019 is partly the response which of course created more death. Not just the federal response which was bad enough but many states and localities. I can't ever forget the bus driver in Detroit who made a video after a female passenger coughed on him. He was fine in the video and dead a few days later. In those days we were required to "elbow bump" and cough into our sleeves
The "guidance" changed a few more times. Biden and Sanders never got the flu, but Rand Paul, Chuck Grassley, Ron Johnson, Mike Lee, Bill Cassidy, Thom Tillis, and Rick Scott all got it. There were treatments but most of them didn't need the treatments. The whole thing is hard to explain. But the federal mortality numbers are backed up by state numbers including red states.
