The claim was that the ancient retroviral LINE1 elements residing inside the human genome would somehow get activated and cause a retrotranscription of the SARS-CoV2 RNA genome, thus allowing its genomic integration. People once infected with the coronavirus would still produce its genes like the spike protein, which would result in positive PCR tests results labelling these former COVID-19 patients as active virus careers. Who knows, maybe they would even produce a functional virus, all their lives? A very worrisome thought.

This should not be surprising. It was already known that viruses can alter DNA.
