I know a couple of people who caught Covid-19 back before the summer, who both described the same symptoms after recovering (and testing negative). This was a while before all this talk of 'Long Covid' came about. Since we're all different, and will all fight viruses in different ways and strengths (depending on health/existing cnditions etc.), there'll be so many variations in how much of a 'toll' fighting it has taken on our bodies (and minds). Since this ia a 'novel' virus, we can only really base any conlusions on the empirical evidence as it comes in.

The virus shouldn't have been labeled 'novel' in the first place. In a 2020 study by La Jolla Institute for Immunology, they found blood samples pre-2018 that demonstrated a T-Cell immune response to Covid-19. It was found that in SARS-CoV-2 and “common cold” coronavirus fragments that were similar (at least 67% genetic similarity) 57% showed cross-reactivity by memory T cells. If the Covid-19 coronavirus is novel, then we should be designating every new strain of the flu as a novel virus.

  If you have many hours to spare, you can watch George Hotz dive into the details. One of the take-aways is that the Corona virus is a Sars, not a flu. https://www.youtube.com/watch?v=8vWaawiUteM https://www.youtube.com/watch?v=8vWaawiUteM If your take is that Sars is just another flu, then I guess you just broadened the scope of the flu, and need to be open for the idea that the 'flu' could be more dangerous than you thought.

  Fragments that were 67% similar really doesn't sound very similar when we're talking about DNA, considering us slower evolving mammals share a larger percentage of DNA with our pets, and by your own stat 43% of people's T-cells are not primed to respond at all... We do designate strains of influenza transmitted from animals (and indeed other coronaviruses transmitted from animals) as novel threats.

    The human genome contains 3 billion nucleotides, SARS-COV-2 contains about 29,000. If it shares ~60% of its genome with common coronaviruses that's quite substantial.

  This is a very weird distortion of terminology. I get it, you hate anti-covid measures (I read your other posts), but most of the "common old" coronaviruses are wildly different from the SARS-2 virus, 67% of genetic difference represent hundreds of years of evolution; the only "similarity" they have is belonging to the same family of coronaviruses. It is like saying, yeah we share 99% of genes with monkeys therefore we are the same thing.
