So here's a question. I am not a virologist, so I'll appreciate forgiveness if this is too far out there.

The Chinese Virus, aka CCP Virus is mutating. Viruses mutate. The CCP Virus is also a chimera, a manmade blend of multiple viruses.

Could one attribute of this genetically modified virus be that it has open receptors, to which another virus could attach itself to, and become part of the CCP Virus?

Such as Marburg or Ebola?

They did it in a lab. Could it happen in nature? Has it already?
