I've been watching this since Carlo Brogna's group first published a suggestive article.

Frankly, I'm in his tent.

I think it's a bacteriophage. It explains much, but not everything about LC. Certainly a big reservoir.

β€˜If the hypothesis proposed, i.e., that under certain conditions SARS-CoV-2 may multiply at the expense of human gut bacteria, is further substantiated, it would drastically change the model of acting and infecting of SARS-CoV-2, and most likely that of other human pathogenic viruses.’
