How does that follow? Where did the virus come from? Viruses don’t spontaneously come into existence in labs.
If it wasn’t made in the lab, then it was already naturally occurring. Which means it didn’t need to escape anything, on account of it existing in the wild before it ever got near a lab.

If something were naturally occurring in a remote location where not many humans were around to cause mass spread, and the virus was being studied (but not engineered or modified) and the virus escaped, that could be an example of a naturally occurring, non-manmade, virus which escaped a lab.

did you not read anything about the article, it talk about novel modification in a lab that is unlikely to occur in nature, not creation out of whole cloth
