Every virus is a parasite. It cannot exist by itself. It depends on his wearer. This is the basic condition of its existence. There's nothing to doubt. What living cell carries viruses? Based on my 30 year old work with bovine leukosis virus (BLV) and HIV has come to the conclusion that the host cells for these viruses are bacteria and yeast. By extrapolating this conclusion, I assume that the host of the coronavirus may also be bacteria or yeast. Bacteria are a complete biological form and we can fight it. By destroying the bacteria carrying the viruses, the virus ceases to exist. According to this idea, many viral infections can be stopped in a similar way.
