Yeah that’s no fun. The flue always takes it toll.
Well, it wasn’t the flu. They did extensive blood work and identified it as an unidentified coronavirus. It was tested and found not to be SARS, SARS-COV1 or MERS but they knew it was a coronavirus. They spoke of “Wuhan” but did not have the test. I also had Influenza-A and pneumonia. The real damage was done by the coronavirus. I had a heart attack the day after admittance. They did a quad bypass to assist healing the damage to the heart, lungs, kidneys, etc. from the coronavirus.
They take blood tests every 4 hr.s to track what’s going on. They can tell which organs are damaged and how badly by chemicals in the blood.
My doctors were intelligent. They were not hindered by Covid protocols at the time. They knew the difference between influenza-A and a coronavirus. They knew the organ damage was from the unknown coronavirus. At 6 am shift change they would meet in my room to discuss this. So I was lucky to know what was going on.
