I strongly suspect there absolutely is. Just look at the legions of patients suffering from long COVID (which btw, is still a thing even if you get vaccinated, though getting vaccinated significantly improves your chance of living and uh...not getting long COVID or sometimes even COVID to begin with), and compare the symptoms of those patients that had sepsis, septic shock, or were in the ICU for some reason. To see folks with the exact same reason with nothing else similar is kind of mind blowing.
The virus <-> human relationship is something we are long overdue to understand.
I could practically write it on my gravestone.
P.S. You folks don't want COVID or PICS or any other disease, so please get vaccinated, keep ALL your vaccines up to date. Oh and if you aren't vaccinated for measles, please do so, because if you aren't vaccinated against it and catch it, you have to do every single one of those vaccinations all over again because your buddy "M" reset your immune system.
