That would be because they are slapping them on ventilators.
My wife and I had it before it had a name, and I have the persistent IgG and IgM antibodies to prove it.
It was the worst flu we ever had in terms of crap in our lungs that we had to cough up.
It literally took months to clear it all out. We were worn out from coughing day and night, but our lungs finally cleared out.
The key is coughing to clear out your lungs.
The worst thing they can do is put you on a ventilator so you can't cough and the crap keeps accumulating in your lungs.
I personally believe they want to kill people to pump up the numbers.
PS - We survived it without doctor visits or drugs.
