Important excerpt from above article:
“A more devious feature is that the virus also contains an integrase enzyme, an enzyme that can insert a piece of the new viral DNA somewhere into human DNA (step 5). With HIV (human immunodeficiency virus), this insertion of the viral DNA happens in almost all infected humans. A similar insertion of COVID DNA into human DNA has recently been observed by three science laboratories studying SARS CoV-2. With HIV patients there is no cure after this happens, and they are on antiviral medication for the rest of their life. How frequently COVID DNA becomes inserted into human DNA has not yet been determined.
That is simultaneously interesting and horrifying.
