SARS-CoV-2 brings out an endogenous retrovirus protein to cause severe COVID-19 and Long COVID syndrome

Do you know that there are viral genes in all humans? They are called Human Endogenous Retroviruses (HERV). HERVs are nucleotide sequences from viral infections that infected our ancestors millions of years ago. HERVs comprise ∼5-8% of the human genome, with over 22 HERV families.[1] Nucleotides are instructions to make amino acids which are the…
